摘要
由于地形、地貌、地质、土壤、植被和气候条件的不同,岩溶地区和非岩溶地区在降雨-径流计算方面存在一定的差异。在岩溶地区,径流不仅受降雨量、降雨强度和下渗能力的影响,还受下垫面及岩溶发育的影响。介绍了流域产流机理、非岩溶区径流的计算方法,重点分析了西南岩溶地区水文特性和岩溶地区径流的计算方法。
Duo to the diversity in terrain,landforms,geology,soil,vegetation and climate,it is different in rainfall-runoff calculation between the Karst area and non-Karst areas.In Karst areas,the runoff is influenced not only by precipitation,rainfall intensity and infiltration capacity,but also by the land surface and Karst development.The rainfall-runoff mechanism and the runoff calculations in non-Karst area of natural basin are described in the article and the hydrological characteristics of Karst regions are analyzed.Then the methods of calculating runoff in Karst are introduced in detail.
