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。

Abstract:
Through the sampling of the soil at the surface layer in Jiashan County, the soil property data were re- corded 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 accu- mulation 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.
Key words:  soil eco-environment  basic farmland protection  regionalization  Jiashan
