摘　　要：表层带岩溶水的赋存相对均匀,露头多,分布位置高,开发利用难度低,对解决西南岩溶石山地区人畜饮水具有十分重要的作用。在野外调查的基础上,利用GIS强大的空间分析功能与敏感性系数法相结合,选取10表层岩溶泉个影响因子进行敏感性研究。确定了研究区各影响因子最利于表层岩溶泉出露的数值区间,为进一步表层岩溶水资源评价和开发利用规划奠定基础。Epikarst water in outcrop,distribution of high utilization with low degree of difficulty,is very important to solve west-south karst mountain,where it has the role of drinking water for human beings and animals..This paper,based on field investigation,makes full use of powerful spatial analysis function and sensitivity coefficient method of GIS.The sensitivity factors of 10 surface karst springs were selected.The numerical range of the influencing factors in the area which is most favorable to the outcrop karst spring is determined,as lays the foundation for the further evaluation and development and utilization of karst water resources.
