根据国际通用的标准场景和环境脆弱性概念，利用GIS技术，以我国气象、土壤、农业生产等数据为基础，构建农药环境风险评估过程“现实中最糟糕的情况”。针对旱地作物和地下水这一环境系统，将我国划分为6个农药地下水环境风险评估场景区，并在此基础上构建了11个标准场景点，从而形成针对旱地作物的我国农药地下水环境风险评估场景体系。利用欧盟农药环境暴露模型PEARL测试该场景体系，运行结果显示该场景体系科学可行。该场景体系的建立既为运用定量模型进行我国农药环境风险评估奠定了重要基础，也为我国农药环境风险管理、农药登记管理工作提供了技术支持和科学依据。

Pesticide environmental risk assessment is a key part of pesticide registration process. Here we applied the concept of standard scenario system developed by the European Union(EU)to groundwater risk assessment of pesticides used in dryland crops. Precipita-tion, temperature, soil organic matter and pesticide application ways were all considered as the main factors affecting environmental behav-iors and soil concentrations of pesticides. Based on meteorological, soil and agricultural production data, a GIS approach was adopted to es-tablish the standard scenario systems. They consisted of 6 scenario zones and 11 standard scenarios. The PEARL model developed by the EU for simulation of pesticide environmental risk was employed to test the established scenarios. The simulation showed pesticide Aldicarb had high environmental risk but Atrazin and Oxadixyl was relatively safe. These results show that the established scenarios would be useful for enhancing the efficiency of pesticide registration.
