3种标准下农产品产地土壤环境质量评价——以山西省陵川县为例

以山西省陵川县主要农田为采样区,对表层土壤的5种重金属元素Hg、As、Pb、Cd和Cr含量进行了分析,参照《无公害食品蔬菜产地环境条件标准》、《绿色食品产地环境质量标准》和《有机农业生产基地环境质量标准》,对土壤环境进行评价。结果显示：该区域土壤环境质量完全满足无公害蔬菜产地环境和A级绿色食品产地环境的质量要求,不适宜发展有机农业生产。该研究可为农业生产发展规划和有关部门提供科学依据和辅助决策。

Soil Environmental Quality Assessment for Agricultural Producing Area Based on Three Standards- A Case in Lingchuan County,Shanxi Province

The contents of Hg,As,Pb,Cd and Cr in surface soil collected from Lingchuan County,Shanxi Province were analyzed.The soil environmental quality was assessed based on The Non-polluted Vegetable Producing Environmental Condition Standard,The Green Food Producing Environmental Quality Standard and Organic Agriculture Production Base Environmental Quality Standard,respectively.The results showed that the soil environmental quality completely met the requirements of non-polluted vegetable producing environmental quality and A-grade green good producing environmental quality,while were not suitable for developing organic agriculture production,which could provide scientific basis and assistant decision-making for development plan of agricultural production and relevant departments.
