摘　　要：以贵州省平坝县龙井水源地为研究对象,对龙井岩溶水系统的补径排条件、发育规律等特征进行调查研究;并基于地质分析的角度,认为划分其边界条件的依据主要为:地形分水岭、水系分布情况、地表裸露岩溶地貌发育规律、相邻独立岩溶水系统的确定、地下水出露点等。龙井岩溶水系统的发育主要受地表水文网和裂隙构造的影响,以地下暗河为主要形式;并以地下暗河出口为地表排泄点,其水化学类型为HCO_3-Ca·Mg水,适合作为饮用水源。As water source area of Longjing in Pingba country for the study,development characteristics such as supply conditions,runoff conditions,excretion conditions,development regularity were invested and studied.And based on the perspective of geological analysis,it is considered that the evidence for dividing the boundary conditions was mainly the surface water divide,the distribution of river system,the development regularity of bare Karst geomorphology,the determination of adjacent and independent Karst water system,and the groundwater dew point.The development of Longjing Karst water system,with the underground river outlet for the surface excretion point,was mainly influenced by the surface structure of the surface hydrographic net and fissure structures.The hydrochemistry type of Longjing water source area is HCO_3-Ca·Mg water,which is suitable for the drinking water.
