摘　　要：[目的]探讨农产品产地土壤锌在不同环境质量评价方法中的结果精度,为农产品产地认证提供依据。[方法]以吉林省舒兰市为例,通过实地采样,实验室样品分析,运用单因子污染指数法和基于GIS的空间插值方法,根据绿色食品产地环境质量标准进行农产品产地土壤锌的环境质量评价,并进行方法比较。[结果]基于GIS的土壤锌空间插值环境质量评价方法比传统方法的精度高;采用基于辅助因子的土壤锌协同克里格插值评价结果比普通克里格精度高;土壤锌和有机质的协同克里格插值评价方法比土壤锌与高程的协同克里格插值评价方法的精度高。[结论]基于GIS空间插值方法的土壤锌环境质量评价结果比传统方法更具科学性和合理性。[Objective] The aim was to explore evaluated precision on quality of soil environment polluted with zinc in agricultural production areas and to provide references for verification of production area.[Method] In Shulan City in Jilin Province,soils were sampled and analyzed in a laboratory using single-factor pollution index and GIS based spatial interpolation.The quality of environment polluted with zinc was assessed and related methods were compared according to Environment Quality Standard of Green Food Production Area.[Result] Spatial interpolation of zinc in soils based on GIS proved more precise than traditional methods;cokriging method with co-factors was higher in precision than common cokriging;cokriging method with zinc and organic matter was higher in precision than cokriging with zinc alone.[Conclusion] Quality assessment on environment polluted with zinc based on GIS interpolation is more scientific and reasonable than traditional ones.
