摘　　要：里伍铜矿开采已有30多年的历史,铜矿开采对周边的土壤环境产生了重要影响。以里伍铜矿区土壤作为研究对象,参照土壤质量标准及土壤环境质量标准为基础的土壤污染分级标准,经过野外数据采集和室内数据分析,应用模糊综合评判法对铜矿区的土壤环境质量进行了综合评价,并对矿区土壤的重金属含量及空间分异性进行了研究,分析发现里伍铜矿的开采对土壤环境质量具有重要的影响。里伍铜矿的土壤环境质量整体较好,但是部分区域土壤环境质量较差。矿区土壤环境质量由较差到好依次为:堆浸矿泥土<堆浸土<铜矿排污口泥土<原生土壤<铜矿区下游江边土壤。土壤环境质量较好到接近较差区域土壤的修复和保护成为今后矿区土壤环境保护工作的重点。Copper mining in the Liwu has 30 years of history,which has a significant impact on the surrounding soil environment.Taking the soil of Liwu Copper as the study object,collecting and analyzing data,using the fuzzy comprehensive evaluation method to evaluate the soil environment quality,and carring out a study on the heavy metal content and spatial distribution in the soil of Liwu copper,based on soil quality standard and soil environment quality standard（1995） GB15618,we found that copper mining had an important impact on the soil environment quality.The whole soil environment quality is better,but it is worse in some palaces.The soil environment quality followed by the poor to good level is heap leaching soilheap leach soilsoil closed to copper outfallnative soilsoil of copper downstream near the river.The soil remediation and protection in the poor soil environment quality area are the key work in the future.
