摘要 吸附态磷流失是土壤侵蚀的结果之一,不仅造成土壤肥力流失,还是导致水环境恶化的重要因子。吸附态磷流失是非点源污染计算的重要组成部分,通过土壤侵蚀研究吸附态磷流失是目前普遍采用的方法。总结了国内外关于吸附态磷流失的研究现状,分析了我国当前土壤侵蚀中吸附态磷流失研究中存在的问题,认为中国土壤侵蚀中吸附态磷流失研究还不能满足实践应用的要求。因此一方面需要增加实验数量,加强实验深度,坚持连续监测的工作,深入了解吸附态磷流失的机理;另一方面应积极构建适合国情的模型,构建基础信息数据库,开展国外模型在国内的适用性、差异性研究。 The adsorbed phosphorus loss is one of the adverse effects of soil erosion,which results in not only the degradation of soil fertility,but also the deterioration of water environment.The adsorbed phosphorus loss is recognized as an important part of non-point source phosphorus pollution.Studying the adsorbed phosphorus loss by the investigation of soil erosion is a commonly used method.This article summarizes the researches at home and abroad and analyzes the China's current problems of adsorbed phosphorus ...
