Abstract

Water systems are an essential component of the earth's ecosystem, providing vital resources for living organisms and human beings. Therefore, ensuring the health and stability of water systems is imperative for human life and development. Taking Wuhan City as a case study, this paper utilizes QGIS software to obtain MNDWI classification maps from four remote sensing images captured in 1985, 1990, 2005, and 2020. It discusses the rules governing water system evolution and the influencing factors in Wuhan City over the past four decades. The analysis reveals that rapid urbanization has significantly impacted the river system in Wuhan during this period. Specifically, there has been a noticeable decline in the overall lake area, which can be categorized into three stages: a sharp decline from 1985 to 1990, a continuous decline from 1991 to 2005, fluctuation stage from 2006 to 2020. Urbanization rate directly correlates with its impact on river systems while macro policies have played a significant role at different stages of change. The natural sedimentation of lakes leads to the deterioration of lake ecological environment and affects the biodiversity of lakes. Water resources are reduced, and water environment is deteriorated by filling lakes to make land or constructing ponds, which leads to excessive development and utilization of land resources. The construction of lake filling weakens the ecological service function of the lake and destroys the ecological balance. It is noted that the changes in the lake are caused by multiple factors and evolve with time.
