| 摘 要： | 概述了磺酰脲除草剂在土壤中的吸附与解吸附，降解与残留、迁移以及抑制土壤酶活性等环境行为，探讨了土壤pH值、不同土壤类型、土壤水分含量及有机质等环境行为过程的影响，引用分布活性模型来解释除草剂的解吸滞后现象，并对磺酰脲除草剂在土壤中的生物降解和非生物降解机理进行了探讨，并从生态毒性，吸附作用力以及降解模型方面对今后的研究进行了展望。

| Abstract: | In this article,the environmental behavior of sulfonylurea herbicides in soil,which included absorption and de-sorption,degradation,resistance,mobility,and inhibition on soil enzyme activity,was reviewed,and the influences of some soil factors,such as pH, soil type,water content,and organic matter on their environmental behavior were also discussed. Distributed Reactivity Model for Sorption was used to explain the hysteretic behavior of sulfonylurea in soil,and the biotic and abiotic degradation mechanisms were summarized. Some prospects on their ecological toxicity,adsorption strength,and degradation model were also discussed. |
