| 中文摘要: |
| 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。 |
| 英文摘要: |
| The hydrology of the Liuxi River watershed was simulated using the SWAT model and the hydrodynamic 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 environmental capacity of the Liuxi River for COD was 53 141.59 ton per year and 43 988.64 ton per year,respectively. |
