摘要
植被抗蚀护坡的潜能源于它与近地面大气、土壤等的相互作用，具体表现为植被的水文效应和机械效应。对这些效应的科学认识是建立植被坡面生态工程基础理论的前提。在过去几十年里，人们对植被与侵蚀之间的因果关系以及植被的坡面保护作用的认识不断加强，使植被越来越成为控制侵蚀和稳定斜坡的有效手段。由于它比较突出的优点和潜能，这一生物学途径在自然环境保护和工程建设方面已经积累了许多经验，具有不少成功的案例，展现了其广阔的发展前景。
Vegetation is one medium which can maintain equilibrium in the landscape between the destructive forces of instability, and the constructive or regenerative forces leading to stability, through its hydrological and mechanical effects. The theoretical understanding of these vegetative effects is the base of slope eco engineering. In the past few decades, the importance of vegetation in protecting slopes has been stressed by many researchers. The greater awareness that vegetation can play a range of roles in slope protection has made it increasingly a valuable tool in natural environmental protection and civil engineering, and this knowledge has led to a increasing application of vegetation types. Though still be a kind of young techniques, an increasing amount of experience of slope eco engineering of vegetation is gathering from the past practices, and the larger number of successful examples of its applications is showing its great future.
