基于多水源跨流域调水的流域水环境综合整治方法及应用研究——以异龙湖流域水环境综合治理为例

跨流域调水能够有效地解决水资源时空分布不均的问题。文章针对异龙湖水环境恶化和流域水资源短缺的问题,分析了当地的水资源分布情况,制定了以石屏县北部山区为调水水源和以早期建成的三岔河引水工程线路为基础向北拓展作为调水线路的多水源跨流域调水方案,并分析了各水源的可供水量。研究表明,跨流域调水能有效地缓解异龙湖流域社会生产和生态环境用水不足的问题,提升了异龙湖水环境质量,本研究能为其他流域的跨流域调水应用提供有益的借鉴。

Cross-basin water transfer can effectively solve the problem of uneven temporal and spatial distribution of water resources.As regards the deterioration of the water environment of Yilong Lake and the shortage of water resources in the river basin,this paper analyzes the distribution of local water resources.In this paper,a multi-source cross-basin water transfer scheme based on the north mountain area of Shiping County as the water diversion source and the early Sancha River diversion project as the water diversion line is formulated,and the available water supply of each water source is analyzed.The study shows that cross-basin water transfer can effectively alleviate the shortage of social production and eco-environmental water use in Yilong Lake basin,and improve the water environmental quality of Yilong Lake.This study can provide a useful reference for the application of cross-basin water transfer in other river basins.
