Simulation and Optimization of Water Environmental Carrying Capacity of Multipurpose Hydraulic in Xiang River Based on SD Model

Protection and improvement of water environment has become an important subject. Taking Multipurpose Hydraulic in Xiang River as the research object, the system dynamics method is used to establish the simulation model. Five schemes are designed, including quo scheme, economic development scheme , environmental protection scheme, resource conservation scheme and comprehensive development scheme. Use osculation value method to optimize the schemes. The comprehensive development scheme is the best one, which can effectively improve the water environment in the Multipurpose Hydraulic in Xiang River . The study could provide a theoretical basis for coordinated development of water environment protection and the coordination of socio-economic development.
