摘　　要：基于鄱阳湖及周边经济区1∶25万多目标区域地球化学调查评价结果为基础,对高安市土壤与农作物硒的地球化学特征进行研究,并开展了土地质量地球化学评估。结果显示:研究区表层土壤硒含量平均值为0.37mg/kg,Ⅰ、Ⅱ类土壤面积占总面积97.57%,富硒土壤分布范围广;根系土-农作物体系中,花生和水稻中Se含量平均值分别为0.08mg/kg,0.04mg/kg;硒有效态含量与全量比值的平均值为3.64%;研究区土地质量良好,富硒农产品主要为水稻和花生,富硒土地资源具有良好的开发前景。This paper makes research on geochemical characteristics of soil and crops and geochemical evaluation of soil quality in Gao’an City based on 1:250000 multipurpose regional geochemical survey of the Poyang Lake and its surrounding economic zone.The results show that the land quality in the study area is good.The average ratio of active Se content to total Se content is 3.64%.The main selenium-rich agricultural products are rice and peanuts.The average content of selenium in topsoil was 0.37 ppm,area of Se-rich soilsⅠandⅡaccount for 97.57%of the total area.The average Se content in peanuts and rice is 0.08 ppm and 0.04 ppm,respectively.
