摘要:
为了探讨贵州喀斯特地区枯季径流的退水规律，选取Depuit-Boussinesq退水方程对流域退水进行模拟，将退水指数与从DEM数据提取的各种地形因子之间进行分析。结果表明：地形指数基本与退水指数成正比；退水指数与基流指数成反比；岩性和喀斯特地貌对退水指数的影响较大，这两项指标不仅决定了径流的成分，还决定了退水的时间与速度。
Abstract:
In order to study of the low-flow recession law in Guizhou kasrst area, we select the Depuit-Boussinesq equation to simulate ressesion flow. Then we discuss the relationship between recession index and several kinds of terrain factor extracting from DEM. The results showed that: topographic index is directly proportional to recession index; recession index is an inverse proportion to base-flow index; Lithology and karst geomorphology has large influence on recession index and both of the two indicators not only determine runoff composition, but also determine recession’s duration and speed.
