摘  要:
草地植被的地上部分具有覆盖、保护地表,截留降雨和削弱雨滴侵蚀能力的作用,在保水护土方面发挥着重要作用。为探讨草被地上部分的水土保持效应,在系统分析国内外有关草被地上部分控制侵蚀营力研究的基础上,归纳并总结了草被冠层及枯落物对降雨动能和坡面流侵蚀能力的影响、草被盖度与土壤侵蚀的关系、草被地上部分对土壤理化性状的影响等方面的最新研究进展,并提出了一些今后有待深入研究的问题。

摘  要:
The aboveground part of grass vegetation has the functions of coverage, surface protection,interception of rainfall and decreasing raindrop erosion ability. It has an important effect on soil and water conservation. The paper summarized the latest research progress of influence of grass canopy and litter to the rainfall kinetic energy and the erosive capacity of overland flow, the relationship between grass vegetation coverage and soil erosion and influence of grass aboveground part to the soil based on the systematic analysis of the study related on erosive agent control of grass aboveground part both at home and abroad and put forward some issues that need to be further studied in the future.
