研究戊唑醇与氟环唑的光解特征，为其环境风险评估提供依据，采用室内模拟方法，比较了0 Lux（黑暗对照）、4000 Lux和8000 Lux光照处理的戊唑醇与氟环唑在水相中的光解差异。结果表明：戊唑醇与氟环唑在水相中的光解变化率0 Lux处理均小于3．1％，4000 Lux的光解速率为0．013/h和0．029/h，8000 Lux的光解速率为0．031/h和0．045/h。光解动态特征符合一级动力学方程；戊唑醇与氟环唑在水相中的光解半衰期4000 Lux处理为53．3 h和23．9 h，而8000 Lux处理为22．4 h和15．4 h。说明，光照强度对戊唑醇与氟环唑在水相中的光解有重要影响，且戊唑醇光解难于氟环唑。

In order to study on photolysis characteristics of tebuconazole and epoxiconazole,so as to provide the basis for the environmental risk assessment,the indoor simulation method was employed to compare the photolysis differences of epoxiconazole and tebuconazole in the water treated with 0 Lux(dark control),4000 Lux and 8 000 Lux.Results:Photolysis rate of tebuconazole and epoxiconazole processed by 0 Lux in water were less than 3.1%.To 4000 Lux photolysis rate was 0.013/h-1 and 0.029/h-1 respectively,and to 8 000 Lux was 0.031/h-1 and 0.045/h-1 separately.The photolysis half-life of tebuconazole and epoxiconazole under 4000 Lux was 53.3 h and 23.9 h,but under 8000 Lux was 22.4 h and 1 5 .4 h.Light intensity had important influence on photolysis of tebuconazole and epoxiconazole in the water and tebuconazole was harder to be photolyzed.
