摘要
基于1:5万土地质量地球化学调查获取的土壤重金属元素、养分指标和土壤理化指标测试数据,采用单指标评价法分别评述了崇仁县过埠-杰坝地区土壤养分和土壤环境质量等级,进而将两者进行叠加分析,划分调查区土地质量地球化学等级。研究结果表明,过埠-杰坝地区土地质量总体良好,初步圈定无公害富硒土壤面积69.41 km^(2),集中连片无公害富硒农业基地3个,可建立中小型无公害富硒农业基地。
Based on soil heavy metals, nutrient element and soil physicochemical index test data obtained by 1:50000 land quality geochemical survey in Guobu-Jieba area, the author reviews the soil nutrients and soil environmental quality grade respectively by the single index evaluation method and makes an overlay analysis to partition the land quality geochemical grade of the surveying area, whose results show that the overall quality of the land in Guobu-Jieba terraced field is good with 69.41 km;pollution-free selenium-rich soil area and three contiguous pollution-free selenium-rich agricultural bases, providing the conditions for establishing small and medium-sized pollution-free selenium-rich agricultural bases.
