摘要
通过嘉善县表层土壤采样分析,取得了0.5km×0.5km网格密度的土壤元素数据,依据绿色食品产地土壤环境质量标准、农用地肥力分级标准、土地富硒标准、灌溉水水质标准,评价土壤生态环境质量。综合各评价成果,结合土壤重金属累积及酸化速率,依据嘉善县基本农田约束性保护指标,应用GIS划定该县基本农田保护区。
Through the sampling of the soil at the surface layer in Jiashan County,the soil property data were recorded with the grid of 0.5km＊0.5km.According to the standards such as soil environmental quality standard of green food production area,soil fertility classification standards,selenium-enriched standards,and irrigation water quality standards,this paper evaluated the soil ecological quality of Jiashan County,analyzed the heavy metal accumulation rate and the acidification rate,and then regionalized the basic farmland protection areas using the GIS methods based on the binding basic farmland protection index.
