摘　　要：土壤 植物系统复合污染研究是污染生态学的科学前沿 ,对于农业环境的生态安全具有重要意义 .本文对复合污染概念的由来及其内涵的发展、土壤 植物系统可能发生的复合污染类型及其研究进展、土壤 植物系统复合污染所导致的生态效应及其定量表征进行了较为系统的概述 ,提出了土壤 植物系统中重金属 有机污染物和有机污染物 病原微生物也是复合污染的重要类型 .指出了多种污染物交互行为、次生产物及其老化、分子毒理机制等方面的研究是今后土壤 植物系统复合污染的研究重点 .同时对复合污染的研究方法以及结果的应用进行了展望 ,为土壤污染的预警防治与修复提供依据 .The research on combined pollution in soil plant systems is a scientific frontier of pollution ecology,and has an important significance in ecological safety of agricultural environment. The origin of combined pollution as a conception and its connotation development were reviewed. Types of combined pollution occurred in soil plant systems and relevant progresses in this area were summarized. Ecological effects resulted from combined pollution of soil plant systems and their quantificational tokens were expounded. The interactions of heavy metal organic pollutant and organic pollutant pathogenic microorganisms were pointed out to be important combined pollution in soil plant systems, and the studies on the interactions, sub products and their aged process,and moletoxicology mechanism of multi pollutants were suggested to be the future keystone contents in this area. Meanwhile, the prospective studies on the methods and application of the results of combined pollution were put forward to provide a support for the warning and remediation of soil pollution.
