摘要
植被是防止水土流失的积极因素 ,也是土壤侵蚀预报研究中的重要因子。系统分析了国内外有关植被的冠层对降雨的截流作用以及对降雨侵蚀动力的影响 ,地表枯枝落叶层的水土保持作用、植被覆盖度与水土流失之间的关系和地下根系提高土壤抗冲性等方面的研究。旨在综合已有研究经验和成果 。
Vegetation is a positive factor to prevent soil and water loss, and also is an important factor for soil erosion prediction. Aiming at promoting relative studies in future on the basis of synthesizing existed results and achievement,some relevant studies are systematically analyzed,such as canopy interception and its effect on the rainfall erosivity, effect of litter layer on conserving soil and water, the relationship between vegetation coverage and soil loss and water runoff, and the improvement of root system on soil anti scourability.
