摘　　要：我国西南地区岩溶广泛发育,其地下水动态特征不同于其他地区,而岩溶山区盆地作为较为普遍的岩溶组合地貌,在大气、地表、地下三水动态联系中有本身的特殊性。该类水文地质单元多分布在黔北、渝南、湘西北地区,且分布广泛,地下富水便于开发,可用以解决盆地周边缺水地区的用水问题。因此研究该类地质单元的水资源评价方法,对于指导岩溶水开发、解决城乡用水有着重要的意义。以四衙坝水源地为例,讨论其特有的地下水径流特点、水源补给、排泄特征等问题。并建立数值方程模拟评价岩溶山区盆地水资源,并与实测结果进行对比。Karst extensively developed in southwest region of China. Its dynamic characteristic of groundwater is different from other areas. As a kind of relative common landform, the dynamic link among atmospheric water, surface water and groundwater in Karst mountainous ba sin has its own speciality. This kind of hydro-geological unit mostly and widely distribute in the north of Guizhou Province, south of Chongqing City, northwestern of Hunan Province. The groundwater is rich and easy to develop to solve water-supply problem of the basin surrounding area. Therefore, research on the evaluation method for water resources in such geological unit has important significance to guide the development of karst water resources and solve the urban and rural water-supply problem. In this paper, Siya dam Water-source district is taken as an example, its special characteristics of groundwater, water-source supply, drainage features are discussed. Numerical equation is established to simulate basin water resources and the result is compared with the measuring result.
