| 摘 要： | 推导了V形基本单元的面积-时间曲线,即得到了其地貌瞬时单位线,继而求出其时段单位线,再与净雨卷积,即可求得流域基本单元的汇流过程.以星丰流域为例,进行了流域基本单元汇流计算,得到了令人满意的结果.这在一定程度上促进了流域汇流理论的发展,必将在推进水资源开发利用、洪水预报、水污染防治以及湿地生态保护等方面表现出重要的理论意义和应用价值. |
| 关 键 词： | 流域基本单元 汇流 面积一时间曲线法 星丰流域 |

| Abstract: | The area-time curve of V-shaped watershed basic unit,namely geomorphology instantaneous unit graph,is deduced,through which time unit hydrograph is gotten.Then the concentration flow process of watershed basic unit is simulated through the convolution between time unit hydrograph and net rainfall process.Taking Xingfeng watershed as a case,its watershed basic unit concentration flow is simulated and the results are satisfactory.The method proposed in this paper develops the theory of watershed concentrateio... |
