From the aspects of mechanics effect and hydrology effect of vegetation, the action mechanism of ecological slope protection was analyzed. The method and the adaptation scope of ecological slope protection techniques were introduced. Starting from the plant succession and the biodiversity theories, combined with plant biological characteristics and climatic conditions of each region in China, the suitable ecological slope protection vegetation communities for six regions in China were listed. The theory of using grasses and shrubs planting techniques for the selection of optimized plant community for ecology slope protection was proposed. Finally, some countermeasures for the existing problems of ecological slope protection were proposed.%从植被的力学效应和水文效应2个方面分析了生态护坡的作用机理;介绍了生态护坡技术方法和适应范围;从植物演替和生物多样性理论出发,结合植物生物学特性,根据中国不同地域和气候条件,列举出了适合于中国6大区域生态护坡的植物群落,并提出草灌结合种植技术为生态护坡最佳植物群落选择的理论;最后对生态护坡存在的问题提出了一些对策.
