At first , the relations between vegetation structures and their controlling soil erosion are discussed . the results show that magnitude of plant community coverage or canopy closure is n ' t certainly the adequate condition of an anti - erosive effective community because the community function of soil and water conservation is related to height of coverage layer as well as community coverage or canopy closure 首先,讨论了植被结构与其防止土壤侵蚀作用的关系,结果表明,植被盖度或郁闭度的大小并不一定就是防蚀有效植被的充分条件,植被保持水土功能还与覆盖层的高度密切相关,覆盖层高度大并不有利于植被保持水土。
