Soil around drainage in a gold mine in Tongguan County was chosen as the research subject, and 7 heavy metal pollutants in the soil including nickel, titanium and cobalt were evaluated and analyzed, with the intention to find out the theoretical basis for establishing an artificial ecological restoration system. The test results indicated that the polluted degree of soil samples by heavy metal cadmium is very severe, with the single average pollution index value 22. 59 and the highest value 50. 59 times more than the standard value. Though chromium,nickel and strontium pollution are relatively slight, the average values still reach the slight and moderate pollution levels. The rubidium, titanium and zirconium contents don't reach the pollution level for the time being. The correlation analysis shows that close correlation exists among chromium-nickel-cobalt, which indicates that the same or similar pollution sources exist around them.%以潼关县某金矿排水沟附近土壤为研究对象,对土壤中Ni、Ti和Co等7种重金属污染状况进行评价与分析,以期为金矿周围土壤污染的人工生态修复提供科学依据.研究结果表明:矿区附近土壤中Co均已达到极严重污染水平,单项污染指数平均值为22.59,最大值超过评价标准的50.59倍；Cr、Ni、Sr污染相对较轻,但其平均值也已达轻度或中度污染水平；Rb、Ti、Zr在矿区内暂无污染.相关性分析表明,Cr - Ni - Co之间有较高的相关性,它们可能有相近或相同的污染源.
