摘　　要："5·12"汶川大地震造成大量滑坡、泥石流、崩塌等地质次生灾害,使当地的生态环境造成严重损毁。本文在深入调查汶川县映秀镇老虎嘴崩塌山体的微地形地貌、岩石大小及土壤含量等特征的基础上,将崩塌山体的微生境划分为碎石坡面、巨石坡面、碎石地、洼地和沟槽地5种类型,以及石面、石缝、石丛三种超微生境。通过不同微生境和超微生境的植被恢复试验,总结了地震灾区崩塌山体植被恢复技术,以期为地震灾区植被恢复技术提供参考。Wenchuan Earthquake on May 12th, 2008 caused landslides, debris flows, and rock falls, and the local environment was seriously destroyed. On the basis of investigations on the character of micro- hypsography, rock size, and contents of soil in a landslide of the Laohuzui Mountain lying in the Yingxiu town of Wenchuan county, the microhabitats for vegetation recovery were divided into five types：gravel slope ,rock slope, gravel land, lacuna land, and groove land. And ultramicro habitats were divided into three types：rock surface, rock aperture, and gravel rocks. Vegetation recovery tests were conducted in the micro-habitat and ultramicro habitat for the disaster areas, vegetation restoration technologies were summa- rized in this paper, aiming to provide reference for restoring vegetation in the disaster areas after Wen- chuan earthquake.
