摘要
植物篱技术是众多治理面源污染问题的措施之一,作为一种新型、有效的坡地管理技术,是农林间作技术的发展。植物篱主要通过控制水土流失、减缓坡面、改变氮磷等面源污染物在坡面的分布状态并降低其含量等途径,起到控制面源污染的作用。通过阐述植物篱技术在国内外的研究现状及其控制面源污染的机理,指出其在我国的应用及存在的问题,以为该植物篱技术更广泛的应用和推广提供参考。
Alley cropping technology is one of the numerous control measures of non-point source pollution.As a new kind of effective sloping management technology,it is the devlopment of forestry intercropping technology.Alley cropping controlled the non-point source pollution by controlling soil erosion,slowing slope and changing the distribution state of nitrogen and phosphorus,even reducing nitrogen and phosphorus contents in the slope surface.The present research situation of alley cropping technology at both home and abroad,also with control mechanism on non-point pollution were discussed,its application in China and existing problems were pointed out.So as to provide references for more comprehensive application of alley cropping technology.
