摘　　要：[目的]探究嘧菌酯在稻田使用后对邻近水塘中水生生物的风险。[方法]首先运用Med-Rice Spreadsheet模型对嘧菌酯在稻田使用后对水生生物的风险进行预测,然后开展了"稻田-鱼塘"模拟系统研究。[结果]模型预测结果和模拟系统的研究结果均表明嘧菌酯对鲫鱼、日本沼虾和中华绒螯蟹的风险较低。[结论]为嘧菌酯在稻田使用的安全性提供科学依据,也可为其他稻田用药的风险评价提供有益借鉴。[Aims] The aim was to explore the risk of azoxystrobin to aquatic organisms in the pond nearby paddy field. [Methods] The Med-Rice Spreadsheet model was primarily used to predict the risk of azoxystrobin which was applied in rice paddy to aquatic organisms and then a simulating paddy field-pond system was established to study the realistic impact on aquatic organisms. [Results] The result of model prediction and simulating study both indicated that the risks of azoxystrobin to Carassius auratus, Macrobrachium nippoensis and Eriocheirjaponica sinensis were low. [Conclusions] The study results could not only provide scientific basis for the safety of the use of azoxystrobin in paddy field, but also could give good reference for risk assessment of other pesticide.
