摘要
运用SWAT和HEC-RAS模型分别构建流溪河流域水文模型和流溪河水动力水质模型,采用改进的分区达标控制法计算流溪河COD的天然及背景环境容量。结果显示,流溪河的COD天然和背景环境容量分别为53 141.59 t/a和43 988.64 t/a。
The hydrology of the Liuxi River watershed was simulated using the SWAT model and the hydro-dynamic-water quality of the Liuxi River was modeling by the HEC-RAS model. On this basis,the natural and background environmental capacity of COD was calculated by using a linear programming model which ensures the standard matching of each water quality control zone. The result showed that the natural and background en-vironmental capacity of the Liuxi River for COD was 53 141. 59 ton per year and 43 988. 64 ton per year,respec-tively.
