摘要
长江湖泊群富营养化问题是水环境目前最为突出的问题之一,并且将伴随湖泊生态系统退化、水环境恶化而越来越突出。构建生态水网工程,增加水体流动性是改善湖泊水环境的有效措施之一。本文以武汉"大东湖生态水网工程"实施为工程应用背景,借助湖泊水网水生态环境模拟分析的有关理论成果,建立大东湖二维水生态环境耦合调度模型,探讨湖泊连通、水力调度对湖泊水生态环境影响的规律,为城市湖泊水生态环境治理和水力工程调度的实施提供借鉴。
Eutrophication of lakes in the Yangtze River basin is one of the most outstanding problems at present,and may become more and more prominent along with the degradation of the lake ecosystem and deterioration of water environment. To build ecological water network and improve the lake water environment, one of the effective measures is to increase water flow ability. Based on the implementation of 'the Project of Dadong Lake Ecological Water Network' in Wuhan and with the help of the simulation analysis theory for water ecological environment, a two-dimensionally coupled operation model of Dadong lake water ecological environment was established to explore the mechanisms and effects of lake connectivity and hydraulic regulation on lake water ecological environment, and to provide a reference for the city ecological environment governance and the implementation of the hydroelectric project scheduling.
