摘　　要：依据南方某区域农业地质与生态地球化学调查取得的区域地球化学资料,按照不同土壤类型求取了研究区的土壤元素背景值,并分别与该区域所在省和全国平均水平进行横向和纵向比较,进而对研究区土壤中各元素及指标的丰缺状况进行分析,从而对现有土壤利用状况作出评价,为该地区土壤污染评价和治理修复提供了重要的地球化学依据,也为农业环境的规划和相应标准的制定提供了基础资料。According to the regional geochemical data obtained from agricultural geology and eco-geochemical investigation of a region in the South, the soil element background values of different soil types in the research area are obtained and have horizontal and vertical comparisons with those of the province in which the region lies and those of the national average level. Then the analysis is made on the conditions of the abundance and scarcity of regional soil element background values and indexes in the soil of the research area in order to provide the basic and comprehensive information for estimating the present situation of soil use, planning the agricultural environment, making the corresponding standards and providing important geochemical data for soil pollution appraisal and repairing.
