摘　　要：通过分析江西省萍乡—新余地区1∶250000多目标区域地球化学调查数据,探讨了深、表层土壤元素地球化学特征,并对研究区进行地球化学分区。结果表明:研究区深、表层土壤元素分布大多较为均匀,W、Mo等分布极为不均匀,深、表层均呈富集现象;研究区划分为3个地球化学区和9个地球化学亚区,其中北部地球化学区Se含量大于0.577 mg/kg,同时Cd含量大于0.428 mg/kg,因此富硒土壤开发中应关注Cd的生态效应。该研究结果可为土地资源合理利用与矿产资源潜力评价提供科学依据。Based on the analysis of 1∶250000 geochemical survey data in the Pingxiang-Xinyu area of Jiangxi Province,the geochemical characteristics of element in deep and surface soils are discussed,and the geochemistry area is divided.The results show that the distribution of elements in the deep and surface soil area mostly uniform,the distribution of W and Mo is extremely uneven,both the deep and surface soils are enriched;the study area is divided into three geochemical regions and nine geochemical subregions.The Se content is greater than 0.577 mg/kg and the Cd content is greater than 0.428 mg/kg in the northern geochemical zone.Therefore,the ecological effect of Cd should be paid attention to in the development of selenium-rich soil.The research results can provide a scientific basis for the rational utilization of land resources and the evaluation of the potential of mineral resources.
