Abstract

As an important resource, water resource has an important contribution to the development of the social economy system. Now the majority of study concentrated on the qualitative analysis and the quantitative analysis is not enough. Based on emergy theory, according to the flow and transformation of water resources in the social economic system, water resources emergy contribution rate (WECR) is put forward in this paper, to reflect the contribution of water resources. And the quantization method of WECR to agriculture, industry, and social life is presented in terms of emergy, which provide a new method for the research of water resources contribution for economic and social development. Taking Zhengzhou as an example, the WECR to agriculture, industry, and social life was calculated from 2005 to 2015, and the average annual contribution rate was 8.55%, 3.68%, 4.71%, respectively. The results showed that water resources have the greatest contribution to agriculture and the lowest contribution to industry. In terms of the trend, from 2005 to 2015, the contribution rate of water resources to agriculture and industry in Zhengzhou city has increased significantly, and the contribution rate to social life has remained within a certain range of values, with slight fluctuations in different years.
