《土壤环境监测技术规范》(HJ/T166-2004)已给出大气污染型、灌溉水污染和农用固体废物污染型等土壤样品采样布点原则，但没有规定金属矿山土壤样品布置原则。由于金属矿山成矿作用复杂性，样品布点设置不清，可能不易分清是自然污染还是人为污染。对广西象州和大新两个铅锌矿区土壤进行调查，获得金属矿体上、下盘岩石风化土壤取样、纳污水体矿坑涌水排污口上、下游取样，地下水排泄口取样，矿体采矿通风口下方、选矿厂破碎系统下方取样分析，可以判定土壤是来自自然污染还是人为污染。

The Technical Specification for Soil Environmental Monitoring (HJ/T1 66 - 2004 )provides the principles for sample point layout of soil samples suffered from atmospheric pollution,irrigation water pollu-tion and agricultural solid wastes pollution.However,there is no principle for layout of soil samples in metal mine.Result from the complexity of mineralization of metal mine,the layout of sample points is unclear, and it’s difficult to distinguish between natural pollution and man-made pollution.Based on the investigation of soil from Xiangzhou Pb-Zn mining area and Daxin Pb-Zn mining area in Guangxi,samples from weathered soil of rocks of upper wall and lower wall of metal orebodies,upstream and downstream of water bursting and drainage outlets of pollutant-holding water body pit,as well as lower part of mining vent and breaking system of dressing plant,it’s possible to distinguish the cause of the soil pollution between natural pollution and man-made pollution.
