| 摘 要： | 农药或其代谢产物进入土壤环境后，可通过多种途径与土壤无机和有机组分形成结合残留物。越来越多的证据表明，在农药土壤环境行为的研究中，应重视其结合残留问题。文章阐述了农药在土壤中的主要结合残留机理，结合残留物在土壤腐殖物质各组分中的分布状况及其环境意义，并对该领域的深入研究提出建议。

| Abstract: | Interaction of pesticide and its metabolites with soil inorganic or organic fractions may form bound residues through many ways in soil. Research has shown that many pesticide and its metabolites form persistent and permanently bound residues in soil that play an important role in pesticide long-time partitioning behavior and its bioavailability and toxicity in soil. In this article, the binding mechanisms, the distribution of pesticide bound residues in soil humus and its environmental significance were reviewed. Furthermore, the possible researches of future in this field were suggested. |
