Abstract: In view of the serious damage to the marine environment of the Bohai Sea, the Chinese government has put
forward a series of policies to manage the marine environment. However, to the authors’ best knowledge, few
existing researches make use of these policies to scientifically and quantitatively analyze the changes of
marine environmental management of the Bohai Sea. Therefore, combined with the marine environmental
management policies of the Bohai Sea from 1982 to 2020, this paper counts the frequencies of key words in
these policy texts which could reflect the policy objectives to analyze the changes of marine environmental
management objectives and the results show that with the continuous development, the marine environmental
management of Bohai Sea has increased the restoration of the damaged marine environment on the basis of
preventing the disruption of marine environment. Meanwhile, on the other hand, this paper contrasts the
specific management contents involved in the marine environmental management plans of the Bohai Sea since
the 21st century issued by the Chinese government and finds that more and more restoration schemes are
developed. Then, based on the analysis results, the tread of the marine environmental management of the
Bohai Sea in the future is predicted. Moreover, solutions to problems in current projects of marine
environmental remediation and restoration by analyzing project implementing processes are explored as well.
As a whole, the management of marine environment of the Bohai Sea is becoming more and more
comprehensive, but there are still some problems such as complicated approval process and no unified
evaluation standard.
1 INTRODUCTION
China is a country with a vast coverage of ocean area
including the Bohai Sea, Yellow Sea, East China Sea
and the South China Sea. Among them, as the only
semi-enclosed inland sea, with an area of 77000 km
2
and an average depth of 18m (Li et al., 2018a) in
China, the Bohai Sea is well-known with its rich
marine resource (Zhang et al., 2009). The Bohai Rim,
which composes Shandong Province, Liaoning
Province, Hebei Province and Tianjin city, is the
agricultural base and heavy industry base of China
(Liu et al., 2015) (Figure 1). The Bohai Sea is located
in the center of Northeast Asia economic circle (Qiu
et al., 2018), which makes the Bohai Rim area one of
the most densely populated and industrialized areas in
China. (Gao et al., 2014; Liu et al., 2015). However,
with the economy development of the Bohai Rim, a
large number of industrial wastewater and
agricultural sewage are directly discharged into the
Bohai Sea. As the Bohai Sea is a semi-enclosed
marine area, the limited water exchange capacity has
led to serious pollution of the marine environment
(Lin et al., 2020; Wang & Wang, 2018). At the end of
the 20th century, the fishery resources in the Bohai
Sea were nearly exhausted, and the species richness
and species diversity decreased continuously (Jin,
2003) (Figure 2).
In order to improve and restore the marine
environmental quality of the Bohai Sea, the Chinese
government has formulated a series of national
marine environmental management policies and the
sub-national policies only for Bohai Sea. In
accordance with various policies including rules,
regulations and plans, actions have been taken to
improve the marine environment of the Bohai Sea,
such as sewage treatment and sewage outlet
inspection (Li, 2014).

Figure 2: The changes of species richness and diversity.
From the founding of China in 1949 to the
beginning of reform and opening up (A period of
rapid economic development in China) in 1979, the
Chinese government formulated marine policies
mainly for the security of its territory and sovereignty,
however, marine environmental problems were
generally ignored (Zhang, 2016). In 1982, the
Chinese government promulgated the Marine
Environment Protection Law of the People's Republic
of China, which is the first law on marine
environmental management in China. Since then,
China has successively issued a series of marine
environmental management policies to improve the
marine environmental quality.
Considering the timing of the promulgation of
policies that have a significant impact on China’s
marine environmental management and the number
of the policies issued in different years (Bai, 2019;
Xu, 2018; Xu et al., 2016; Yu & Bi, 2019), the marine
environmental management policies of the Bohai Sea
from 1982 to 2020 can be divided into the following
five phases.
1) The construction phase (1982-1985). In this
phase, China began to promulgate regulations and
policies related to marine environmental management
in accordance with the Marine Environment
Protection Law of the People's Republic of China,
representing the beginning of the marine
environmental management system of China.
2) The continuation phase (1996-2005). In this
period of time, compared with marine environmental
protection, the Chinese government paid more
attention to the development of marine resources. As
a result, the policies of the previous stage were
basically continued.
3) The refinement phase (2006-2010). This phase
is a period of continuous improvement of policy
system. The administrative intensity of marine
environmental protection policy is higher than that of
marine resources development policy.
4) The diversification and consolidation phase
(2011-2015). In this stage, the marine environmental
management had been further strengthened, and the
management methods had gradually diversified.
5) The innovation phase (since 2016). The
government has paid more and more attention to the
innovation of marine environmental management
model, and began to emphasize the collaborative
management of land and sea, and bring coastline into
the scope of marine environmental management.
This paper firstly employed the word frequency
analysis method to obtain the number of keywords in
the Bohai Sea marine environmental management
policy that could reflect the marine environmental
management objectives in different phases, so as to
analyze the changes of the objectives of Bohai Sea
marine environmental management. Next, Since the
policies issued in the 20th century for the marine
environmental management of the Bohai Sea are
mainly qualitative quotas, this paper analyzes the
changes of specific management contents based on
the quantitative management and control indicators
specified in the management plan proposed since the
21st century. Finally, combined with the
implementation of the current management plan, the
problems existing in the current scheme has been
discussed with the constructive suggestions to the
authorities.
The structure of this paper is divided into six parts.
The first part elaborates the way of dividing the
marine environmental management policies of the
Bohai Sea issued from 1982 to 2020 into different
phases, and describes the structure and potential
contribution of the paper. The second part reviews the
relevant studies based on the marine environmental
management policies of China. The third part deploys
A Policy-based Analysis of Marine Environmental Management Evolution of the Bohai Sea
205
the method of word frequency analysis to
quantitatively count the keywords of policy content,
and analyzes the change of management objectives.
In the fourth part, through the parallel comparison of
the quantitative control indicators in the marine
environmental management plan of the Bohai Sea
formulated since the 21st century, the changes of the
specific management contents of the marine
environment were analyzed. The fifth part discusses
the change trend and existing problems of the marine
environmental management of the Bohai Sea, and
puts forward constructive suggestions to the
authorities. Finally, the main conclusions of this
paper are summarized in part six.
2 EXISTING RESEARCH ON
MARINE ENVIRONMENTAL
MANAGEMENT IN CHINA
In recent years, the Chinese government has laid more
stresses on the importance of marine environmental
pollution problem, and has issued a series of marine
environmental management policies to manage this
problem. Research related to these policies has also
been conducted by scholars to analyze China's marine
environmental management.
(Wang & Liu, 2012) and (Xu et al., 2014)
classified the marine policies of China according to
four standards, including levels, management
objectives, fields and subjects, to analyze the
problems existing in the marine policy system of
China and put forward suggestions. According to the
marine environmental management policies issued by
the Chinese government from 1979 to 2015, (Xu et
al., 2016) used quantitative analysis and content
analysis to study the tendency of the marine
environmental policy system of China and the
proportion of different policy tools used in marine
environmental management. (Zhang, 2016) digested
the contents of the Government Work Report of China
from 1954 to 2015, so as to analyze the change of the
proportion of marine policy in all aspects of
government policy and the change of the focus of
marine management policy. (Xu, 2018) considered
the marine environmental management policies
issued by the government from 1982 to 2015, and
used content analysis and word frequency analysis to
investigate the changes in the concept and structure
of the policy. (Yu & Bi, 2019) divided the marine
environmental management policies issued by the
Chinese government from 1982 to 2020 into multiple
stages, and used mathematical methods to analyze the
evolution process of the policies, such as co-word
analysis and word frequency analysis. (Ma & Zhao,
2019) divided the legal history of the marine
environmental protection of China from 1949 to 2019
into three stages, defined the characteristics of each
stage, and prospected the legal development in the
future. (Wang & Mao, 2019) analyzed the change of
the government's emphasis on marine environmental
management by using content analysis method and
social network analysis method according to the
marine environmental policies issued by the
government from 1983 to 2016. (SONG et al., 2019)
established an evaluation system of marine
environmental management effect, which includes
three aspects: institutional setting and management,
legal system and state of the marine environment. The
results indicated that the legal system of marine
environmental management in China is still in a
backward position. (Yu & Yu, 2021) used the NVivo
software to analyze the qualitative data of coastal
ecological policy documents and found that ecology
is a priority factor in policy-making. In addition, it is
also found that more attention is paid to the process
of policy implementation instead of evaluation and
feedback. (Yu & Cui, 2021) divided the policy
evolution of marine litter governance in China into
three stages based on the important time points of
promulgating policies and extracted the keywords
and calculated their frequencies of each stage, which
are used to analyze and compare the characteristics
and performances of policies of different stages.
From the aforementioned review, it can be found
that, based on China's marine environmental
management policies, most of the existing studies are
still solely focusing on the policy system, such as
establishment and development, instead of analyzing
the objectives and specific contents of marine
environmental management. Therefore, in view of the
impact of management policies on the change of
management objectives and specific management
contents, this paper makes a trial with series of
analysis and discussion to propose a theoretical basis
for clarifying the evolution process of the marine
environmental management of the Bohai Sea.
3 THE CHANGE OF MARINE
ENVIRONMENTAL
MANAGEMENT OBJECTIVES
IN THE BOHAI SEA
Since the Chinese government promulgated the
Marine Environment Protection Law of the People's
WRE 2021 - The International Conference on Water Resource and Environment
206
Republic of China in 1982, a series of marine
environmental management policies have been
promulgated in succession, which have become
important tools for marine environmental
management. This paper selects 102 policies issued
from 1982 to 2020, including national marine
environmental management policies and sub-national
policies only for the Bohai Sea, to analyze the
changes of marine environmental management
objectives of the Bohai Sea. As described in Part I,
the period 1982-2020 is divided into five phases, and
each policy is classified into specific phases
according to the year in which it was enacted.
Based on the key words proposed by (Xu, 2018)
and (Yu & Bi, 2019), which can reflect the core
contents of China's marine environmental
management policies, and the research requirements,
this paper selects 8 key words that can reflect the
objectives of marine environmental management in
the Bohai Sea. The 8 keywords are "Pollution",
"Environment", "Protection", "Ecological",
"Prevention", "Renovation", "Restoration" and
"Reclamation".
This paper uses the word frequency software of
ROST CM6 developed by Wuhan University to count
the frequency of 8 key words appearing in each phase.
Meanwhile, the growth rates of each keyword in
different phases relative to the previous phase are
calculated and the upper and lower growth rates of
each keyword has been calculated (Figure 3).
As shown in Figure 3, along with the advance of
marine environmental management of the Bohai Sea,
the key words "Pollution", "Environment" and
"Protection" appear frequently. The rising trend of
those key words indicates that protecting marine
environment and reducing pollution of the Bohai Sea
are always the objectives of China's marine
environmental management. For example, Marine
Environment Protection Law of the People's Republic
of China (1982), Some Opinions on Further
Strengthening Marine Ecological Protection and
Construction (2009), and Regulations on Prevention
and Control of Marine Environmental Pollution by
Ships (2017) are mainly focus on strictly controlling
the discharge of pollutants into the sea and protecting
the marine environment.
The frequency of the key word "Ecological" is
relatively low in the policies issued in the first phase
(1982-1995), but it increases rapidly in the following
phases. In the two phases of 2011-2015 and 2016-
2020, the frequency of "Ecology" is close to or even
more than that of "Pollution", "Environment" and
"Protection", which indicates that in the 21st century,
the scope of marine environmental management
objectives in the Bohai Sea has been further expanded
on the basis of controlling the discharge of pollutants
into the sea. For example, the 13th Five-year Plan for
Ecological and Environment Protection (2016) and
Opinions of the State Oceanic Administration on
Further Strengthening the Protection of the
Ecological and Environment in the Bohai Sea (2017)
all call for strictly controlling the discharge of
pollutants into the sea and for strengthening
protection of the marine ecological.
The frequency of the keyword "Prevention"
shows a growth rate of greater than zero in each phase
compared with the previous phase, indicating that the
Chinese government has always taken preventing
further damage to the marine environment as the
objective of marine environmental management in
the Bohai Sea. It should be noted that before 2005, the
frequency of "Remediation", "Restoration" and
"Reclamation" was very low, but since then, the
frequency of these three keywords shows a positive
growth trend. This shows that the objective of marine
environment management of the Bohai Sea
emphasizes the restoration of the damaged marine
environment on the basis of preventing the disruption
of marine environment.

4 THE CHANGE OF MARINE
ENVIRONMENTAL
MANAGEMENT CONTENTS IN
THE BOHAI SEA
In the 20th century, most marine environmental
management policies of the Bohai Sea are merely
focused on the setup of the management objectives,
the specific management contents are ignored. Since
the 21st century, the Chinese government has
formulated a series of plans with specific contents and
scale for the marine environmental management of
the Bohai Sea in order to protect the marine
environment more effectively. By sorting out the
management contents and corresponding quantitative
indicators stipulated in these management plans, this
part analyzes the changes of specific marine
environmental management contents of the Bohai Sea
in the past 20 years.
In 2001, for dealing with the serious pollution
problem in Bohai Sea, the Chinese government
formulated the Clean Bohai Sea Program (CBSP) to
strengthen the marine environment management of
the Bohai Sea. The CBSP is the earliest regional
marine environmental management plan at the
national level in China (Tong et al., 2014), which
stipulates that the management plan will be
implemented in three five-year stages from 2001 to
2015 and the specific management content of the
first-stage is to reduce the discharge of pollutants into
the sea. Specifically, by 2005, compared with 2000,
the discharges of phosphorus, ammonia nitrogen,
COD, and oil into the Bohai Sea should be dropped
by 20%, 20%, 10%, and 20%, respectively. However,
an investigation in 2006 showed that there were still
serious problems in the ecological environment of the
Bohai Sea, with the total amount of land-sourced
pollutants into the sea remaining high and the wetland
area shrinking. The CBSP failed after only five years
of implementation (Li et al., 2018b)
In 2007, the Chinese government formulated the
Bohai Sea Environmental Protection General Plan
with a coverage of two stages: 2008~2012 and
2013~2020. The management contents of the first
stage plan include reducing the discharge of
pollutants into the sea. The discharges of COD,
ammonia nitrogen, and total phosphorus should be
reduced from 1.5 million tons to 1.2 million tons, 110
thousand tons to 90 thousand tons, and 105 thousand
tons to 9 thousand tons respectively. In addition, the
restoration of marine ecological environment has
been supplemented to the management contents,
including the restoration of 210 thousand hectares of
wetland area and the increase of 460 thousand
hectares of shelterbelt area. The management
contents of the second stage of the plan are roughly
the same as that of the first stage, with quantitative
indicators include reducing COD into the sea to 800
thousand tons and increasing the area of shelterbelt
by 210 thousand hectares by 2020. In 2013, the
Chinese government proposed the implementation of
The Blue Bay project to restore the marine ecological
environment of seriously polluted bays across the
country, including several bays of Panjin City,
Jinzhou City and Qinhuangdao City in the Bohai Rim.
The Blue Bay project is proposed at the second stage
of the Bohai Sea Environmental Protection General
Plan, so this paper regards the implementation of the
Blue Bay project as a supplement to the restoration of
the marine ecological environment included in the
management contents of the second stage of the
Bohai Sea Environmental Protection General Plan,
including restoration schemes of damaged shoreline
restoration, dredging and the removal of offshore
structures.
When the implementation of the Bohai Sea
Environmental Protection General Plan entered its
final stage in 2018, unfortunately, the ecological
environment of important estuaries, bays and marine
ecosystems in the Bohai Sea is still in a sub-health or
unhealthy state. Hence, the Chinese government
formulated an Action Plan for The Comprehensive
Management of the Bohai Sea to speed up the solution
of the prominent ecological and environmental
problems in the Bohai Sea. The management contents
of the plan include reducing the discharge of
pollutants into the sea and restoring the marine
ecological environment. By the end of 2020, the
proportion of coastal seawater with good quality
should reach over 75% by reducing land-sourced
pollutants into the sea and the natural shoreline rate,
the restored wetland area and shoreline length should
be greater than 35%, 6,900 hectares and 70 km
respectively by means of restoration schemes such as
sand filling, dredging and the removal of offshore
structures.
By comparing the management contents of the
above marine environmental management plans of
the Bohai Sea, one uniform management code can be
summarized: reducing the discharge of pollutants into
the sea. Importantly, the restoration of the marine
ecological environment has also been emphasized
gradually with restoration schemes developed (Table
1).

5 RESULT AND DISCUSSION
5.1 Evolution Trend of Marine
Environmental Management in the
Bohai Sea
According to the analysis of the change of objectives
and contents of marine environmental management in
the Bohai Sea, it is recognized that before 2005, the
key words related to restoration are rarely mentioned
in the marine environmental management policies of
the Bohai Sea, but since 2005, relevant keywords
have been mentioned repeatedly with a rising trend.
In addition, by analyzing the specific management
contents of the marine environmental management
plan of the Bohai Sea in the past 20 years, it can be
found that the restoration schemes corresponding to
the marine ecological environment restoration are
becoming more and more comprehensive. However,
it is worth noting that in the General Plan for
Environmental Protection of the Bohai Sea issued in
2007, the specific contents of marine environmental
restoration of the Bohai Sea are proposed for the first
time, so far just 13 years. Naturally, the mature
marine environmental restoration system of the Bohai
Sea has not been formed. Therefore, it can be
predicted that marine environmental management of
the Bohai Sea in the future will continue to focus on
reducing the discharge of pollutants into the sea and
restoring the marine ecological environment, and
gradually form a mature marine environment
restoration system of the Bohai Sea.
5.2 Existing Problems and
Countermeasures in the Marine
Environmental Restoration of the
Bohai Sea
The recent management plan for marine
environmental restoration of the Bohai Sea is the
Action Plan for The Comprehensive Management of
the Bohai Sea, which was promulgated by the
Chinese government in December 2018 and finished
by December 2020. The plan involves 64 marine
environmental restoration projects. This paper firstly
summarizes the process of 26 related projects and
finds out the existing problems, then analyzes the
possible causes of these problems, and finally
proposes exploratory solutions.
The process of marine environmental restoration
project of the Bohai Sea generally includes eight
steps: review, approval, preliminary work,
preliminary design, environmental impact
assessment, construction, completion acceptance and
project acceptance. In August 2019, all the 26
projects passed the review. However, by March 2020,
7 of the 26 projects are in the approval step, 3 projects
in the preliminary design step, 13 projects in the
environmental impact assessment step, and only one
projects in the construction step. It can be seen that
overall progress is slow and the projects are
A Policy-based Analysis of Marine Environmental Management Evolution of the Bohai Sea
209
concentrated in the environmental impact assessment
step.
The main causes of these problems may include:
(a) The process of the project is cumbersome,
requiring a complex approval process for each step
and each step should be executed in strictly sequential
order;
(b) The lack of unified standards for
environmental impact assessment of marine
environmental restoration projects in China makes it
difficult to pass the environmental impact assessment
step.
In view of the existing problems in marine
environmental restoration of the Bohai Sea, this paper
suggests that, on the one hand, the process of marine
environmental restoration project should be
simplified, such as reducing the number of approval
steps or taking place simultaneously. On the other
hand, the environmental impact assessment standards
for marine environmental restoration projects should
be promulgated as soon as possible.
6 CONCLUSIONS
Dealing with the deficiencies in the academic
research on marine environmental management of the
Bohai sea, with a special focus on the marine
environmental management policy content, this paper
tried to exploring the existing problems in marine
environmental restoration of the Bohai sea based on
the detail investigation of the objective and content
changes of marine environmental management in
Bohai sea since 1982. Future marine environmental
management direction of the Bohai sea has also been
predicted with exploratory solutions proposed in this
paper.
From 1982 to 2020, great changes have taken
place in the marine environmental management of the
Bohai Sea. The management objective has changed
from targeted pollution control to comprehensive
ecological management, and the management content
has increased the marine environmental restoration
on the basis of reducing the discharge of pollutants
into the sea. In addition, the marine environmental
restoration schemes are becoming more and more
comprehensive. From the simple vegetation
restoration, various schemes such as coastal
restoration, dredging, and offshore structure removal
have been gradually added. It is expected that marine
environmental management of the Bohai Sea in the
future will continue to take into account the reduction
of the pollutants into the sea and the restoration of
marine ecological environment. The marine
environmental restoration project will further
simplify the process and promulgate the
environmental impact assessment standards as soon
as possible, which are currently the key issues to be
addressed in China. Study in the policy evolution of
environmental management scheme in China can also
provide importance hints and directions for other
developing countries, which are now suffering from
the environmental problems caused by the reginal
economic developments.
