摘　　要：以丽江市玉龙县境内的黑龙潭地区为主要研究对象,总结了已有的水文地质资料,分析了九子海-黑龙潭地区的岩性、构造等特征。通过对研究区内及周边泉的调查研究,认为北衙组中段、上段的灰岩、白云质灰岩是研究区的主要含水层,地形切割上述含水层使得地下水出露成泉。对水样进行了水化学聚类分析和氢氧同位素分析,发现含水层主要接受大气降水的渗透补给。按照水力联系对泉点进行了划分。根据研究区内及周边地区的泉点分布分析了地下空间的特点和地下水的联系。研究结果对泉群的利用、保护具有参考价值。Taking the Heilongtan area of Yulong County in Lijiang City as the subject investigated has summed up available hydrogeological information,and analyzed lithologic and structural features in the Jiuzihai-Heilongtan district.Through the investigation of springs in the study area and periphery have considered that the limestone,dolomitic limestone in the middle and upper members of the Beiya Formation are the main aquifers in the area,as a result of topographic dissection made the water in aquifers exposed into springs.Through water sample hydrochemical clustering analysis and hydrogen-oxygen isotope analysis have found that the aquifers are mainly recharged by percolation of atmospheric precipitation.Based on hydraulic connection has carried out springs partitioning in the area.According to springs distribution in study area and periphery have analyzed underground spatial features and their relationship with groundwater.Thus the study result has referential values in utilization and protection of springs.
