| 摘 要： | 农药在土壤中的淋溶受许多因子的影响与制约。本文根据农药在土壤中的环境行为，建立了农药土壤残留动态与淋溶归宿的计算机模型，并用此模型计算了模拟各种不同环境条件下涕灭威农药在土层中的淋溶情况。结果表明：农药的使用量、土层中农药的降解半衰期、施药地区土壤的质地、降水或灌溉水量及其距施药后的时间对涕灭威在土层中的淋溶有较大的影响，而土壤有机碳含量则影响不大；地下水埋深对农药地下水污染的影响颇大。地下水埋深不足１ｍ的地区，极易受农药的污染。

| Abstract: | Tbe leaching of pesticide in soil is affected andcontrol led by many factors;Acomputer model for pesticlderesidue, leaching and fate in soil was established according to the hebavior of pexticide in soil environment.This model wasused to study the fate of Ald icarb insoil under differentcomditions. The results showed that Aldicarb application site,the amount and time of precipitation and/or irrigation after the pesticide application were proved to have great effects on itsleaching in the soil profile,and the soil organic carbon contenthad less influence.The depth of groundwaterhad fairly greatinfluence to pesticide groundwater contamination.When thegroundwater depth is less than one meter,groundwater is vul-nerable to pesticide contamination. |
