Yunnan Mengxing lead mine is located in the Nu River and holding Mengxing Bazi North-South divide west slope zone, and restricted by the attitude of stratum and tectonic, forms a monoclinic artesian arrisway as an independent hydrological geological unit. Based on the collection of the system samples during thewet season (rainless period) and multicomponent water quality analysis in the mining area, on the basis of research and analysis of hydrogeology in mining area, application of factor analysis and correspondence analysis in mathematical statistics is to discuss the classification and division of water quality. The theoretical method and the analysis results are helpful for further popularization and application.%云南勐兴铅矿矿区位于怒江与勐兴坝子夹持的近南北向分水岭西侧的斜坡地带,受地层产状及构造制约,构成单斜自流斜地,为独立的水文地质单元.通过对矿区丰水期(枯水期)进行系统样品的采集并进行多成分水质分析,应用数理统计中因子分析和对应分析的方法对水质的分类和划分进行探讨,其中理论方法和分析结果有助于进一步推广应用.
