摘　　要：通过对重庆缙云山暴雨雨水及5个样地(常绿阔叶林、针阔混交林、楠竹林、灌木林、农用地)的地表径流、地下径流水质进行监测,检测了12个指标,对水质数据进行主成分分析,提取了4个主成分,得出11个样本在主成分上的标准得分,据此进行聚类分析,将其划分为5类,并对其进行讨论分析。结果表明,大气降水的水质优于地表径流和地下径流,5个样地的水质等级为:灌木林>农用地>楠竹林>混交林>阔叶林,林地地下径流水质优于地表径流,农用地地下径流水质劣于地表径流。Accorcling to the investigation of rainstonn rainwater, surface and underground runoff water quality of 5 land use types（broadleaf forest, mixed wood, bamboo forest, shrub forest and farndand） in Jinyun Mountain, 12 index were selected and 4 principal components were extracted after PCA（principal component analysis） . Then the score of principal component was calculated, and 11 samples were divided into 5 clusters by the method of cluster analysis. The study showed that the rainwater quality was better than that of surface and underground runoff, water quality class of typical forests was： shrub forest 〉 farmland 〉 bamboo forest 〉 mixed wood 〉 broadleaf forest, and underwater runoff water quality of forest lands was better than their surface runoff. In contrast with forest land, the farmland was opposite.
