    摘要:

    建立了一个基于三种农药在土壤中根区和中间渗流区迁移能力的模型,并采用不同类型土壤分布区域的土壤理化性质、区域气候与水文特征以及农药理化性质等参数,进行了农药对区域地下水潜在污染能力的评价。结果表明多效唑较易污染地下水,杀虫双次之,而氟乐灵极不易。红壤分布区域的地下水特别容易受到农药的污染。在种植水稻的情况下,农药对地下水污染的潜在威胁增大。

    Abstract:

    Reports of groundwater contamination by several pesticides have increased in recent years. In this work, one model in terms of pesticides' potential to leach through the crop root zone and to intrude into grounderwater was established to evaluate the potential of pesticide groundwater contamination with soil characteristics, regional climate and pesticide properties as its running parameters. The results showed that paclobutrazol was more likely to contaminate groundwater than dimehypo, but trifluralin was very unlikely. Groundwater in red soil region was very likely contaminated by pesticides. In case of rice planting, the potential threat of pesticide groundwater contamination increased.
