Based on the chemical plant site classification of different regional pollution,heavy metals and pesticides pollution(HCH,DDT)in the soil of chemical plant sites were analyzed,and the repair plans according to the pollution characteristics of various pollution area were made. Research results and engineering examples in the premise of safety protection and secondary pollution prevention measures,showed that taking“excavating cleaning+off-site disposal,chemical leaching and biological repair”and other repair technology of combined use for heavy pollution pesticide plant and chemical plant are feasible.%通过对化工厂场地划分不同的污染区域，总结分析生产农药的精细化工厂场地土壤中重金属及农药六六六、滴滴涕的污染情况，并针对各个污染区域的污染特征研究制定修复方案。目前的研究成果及工程实例说明在做好各项安全防护和防治二次污染措施的前提下，采取“开挖清理+异地处理处置、化学淋洗和生物修复”等多种修复技术联合使用的方案对重污染的农药厂、化工厂是可行的。
