| 摘 要： | 通过对潜江市气象、施药方式等方面调查，应用SoilFug模型预测农药的分布、归宿，结果表明农药的大部分是通过降解作用而从环境中除去的，挥发和径流的比例很小．应用模型计算了全年降雨径流中农药浓度，以峰值浓度和平均浓度分别进行安全用量估算(kg／ha)：甲草胺1．8～13．8、丁草胺14．55～30、甲胺磷1．95～5．1、乐果2．25～4．2、敌敌畏2．85～7．0，甲基对硫磷0．53～1．2、对硫磷2．25～4．05，甲基对硫磷对环境的风险最大。

| Abstract: | On the basis of analyzing the meteorology and pesticide application mode, SoilFug model was used to simulate the distribution and fate of pesticides. Most of the pesticides are removed from the environment by degradation, and a few by evaporation and runoff. The model calculated pesticides concentration in runoff for all year time. According to the peak and average concentration, safe dosage are estimated as follows (kg/ha): 1.8~13.8, 14.55~30, 1.95~5.1, 2.25~4.2, 2.85~7.0, 0.53~1.2 and 2.25~4.05 for alachlor, butachlor, methamidophos, dimethoate, dichlorvos, parathionmethyl and parathion respectively. Among them, parathionmethyl is the most risky to water environment. |
