中文摘要：
从区域岩溶水系统分析入手，详细论述了龙何地区表层带岩溶水系统的结构特征及水循环过程，并按水动力条件将区内表层带岩溶水系统划分为若干个汇流状或散流状表层带岩溶水子系统。在此基础上，通过表层岩溶泉长观数据的统计分析得出本区表层带岩溶水天然资源量为31．9×10^4m^3／a，约占本区年降水总量的9．5％。在表层带岩溶水天然资源量中，表层岩溶泉的可开采资源量为5．9×10^4m^3／a，可有效利用资源量为7732．4m3／a。
英文摘要：
The paper starts with analysis on regional karst water system and elaborates the structure of the epikarst water system and water circle process in Longhe. According to hydro-dynamic conditions, several confluence type or scattered flow type of epikarst water subsystems are subdivided. Based on statistic analy- sis on long-time observation data of the epikarst springs, it is concluded that the quantity of natural epikarst water resources in the area is 31.9 ×10^4m^3/a, about 9.5% of rainfall can be drawn. Among the quantity of natural epikarst water resources, the exploitable water resource from epikarst springs is 5.9×10^4m^3/a and the effective amount is 7 732.4m3/a.
