【摘要】 "5.12"汶川大地震造成的滑坡、泥石流、崩塌等地质次生灾害使当地的植被毁坏严重,微立地因子植被恢复法适用于地震灾区复杂的立地条件植被重建。在研究灾区植被破坏类型的基础上,将损毁植被的坡面划分为岩质边坡、土质边坡、土石边坡3种类型,并对不同坡面进行微立地因子类型划分,针对不同立地条件选择适宜植被恢复技术,促使灾区尽快植被重建,并为微立地因子植被恢复法的完善提供重要依据。更多还原

【Abstract】 Wenchuan Earthquake on May 12th,2008 has caused landslides,debris flows,and rock falls,and the local vegetation was destroyed seriously.Micro-site factors revegetation technology is appropriate to the site with complex conditions and it has a broad applicability to revegetation.On the basis of studing the types of vegetation damaged slope in the disaster areas,sites for revegetation are divided into three types: rock slope,earth slope,earth-rock slope.And then we divided micro-site types for each slope type,choose suitable vegetation restoration technologies for the disaster areas.That will make disaster areas revegetation effectively,and provide an important experiences for perfecting of micro-site factors revegetation technology.更多还原
