龙昆沟是位于海口市主城区的排洪河道，受人类活动破坏和潮水顶托影响，水体污染严重。拟利用现有水利工程对龙昆沟水系进行联合调度，以改善其水环境现状。为确定合理调水方案，以不同潮位和调水流量作为边界条件，构建水动力水质模型，模拟水量水质变化过程。结果表明，枯水大潮和枯水小潮期应分别采用间断性和连续性调水，红城湖与东西湖联合调水可有效地解决龙昆沟、大同沟及东西湖水质问题。

Longkungou ,which is located in Haikou ,is the main drainage channel of the city .It has been seriously polluted by the human activities and tide push .Regarding to this situation ,it was proposed to divert clearer water from other lakes and rivers in Longkungou river system into Longkungou by adopting the existing hydraulic channels ,so as to improve its wa-ter environment .In order to determine a suitable water diversion plan ,a hydrodynamic water quality model was established to simulate the changing process of the flow and quality with different tide levels and water diversion amounts as the bound-ary conditions .The results suggest that intermittent mode and continuous mode should be adopted during the low water high tide and low tide period respectively .Besides ,the combined water diversion from Hongcheng lake and Dongxi lake can solve the water quality problems of Longkungou river ,Datonggou river and Dongxi lake at the same time .
