摘要

养分流失造成水体的富营养化

致使水体恶化已是不争的事实

寻找有效的氮素源头控制方案对于改善水环境具有重要意义。聚丙烯酰胺(PAM)被认为是最有潜力的土壤改良剂

尤其是在调控土壤养分流失

维持良好生态方面受到高度关注。通过室内人工降雨模拟试验方法

设定不同雨强和不同PAM施用水平

了解PAM影响产流产沙水平及调控土壤氮素流失效应。试验结果表明

PAM的施用可以降低地表氮素流失水平

而其主要原因在于影响地表产流产沙水平。

Abstract

Eutrophication caused by nutrient lost always lead to water environment deterioration.To find effective source control technology has important significance for improving water environment.As the most potential soil conditioners

PAM has been received high attention on regulating nitrogen loss and maintaining great ecosystem.The research

conducted by simulated rainfall

was to determine the effect of runoff

sediment and nitrogen loss with PAM application under different rainfall intensity and PAM application ...
