The quality of water bodies is closely related to environmental climate and human activities. In order to enhance the environmental quality of water bodies, this project implements four major tasks, hoping to strengthen the optimized management of water bodies and achieve the purpose of water quality improvement. Future climate change will lead to hydrological conditions such as rising temperatures (water temperature), extreme heavy rainfall, and droughts, affecting the quantity and quality of water resources, impacting water environments (including ecology), and socio-economic activities. This project studies the impact of climate change on the water quality of water bodies and proposes adaptation strategies and action plans. The United Nations seventeen Sustainable Development Goals in 2030, "Clean Water Resources" are mentioned, emphasizing the acquisition and reuse of water resources. Therefore, our country is currently promoting the selection of concerned substances in policies and conducting in-depth research on the treatment and recycling technologies of concerned substances to improve resource utilization efficiency and benefits. Additionally, in our country's Green GDP accounting for water pollution, four accounts are mainly compiled: physical flow, emissions, quality, and damage, to understand the impact of socio-economic development on water pollution, as well as the pressure that the water environment still needs to bear after pollution prevention and control. Based on research results such as the cost-effectiveness of wastewater recycling and reuse processes and basin pollution control, they serve as the basis for future basin pollution control strategies.At the same time, this project also assists in analyzing reservoir water quality, providing review opinions on the simulation of ground water body water quality for environmental impact assessment cases.
