基于植物多样性指数对汶川地震灾区崩塌山体的微生境植被自然恢复力评价

Appraisal of Vegetation Resilience of Microhabitats of a Collapse Mountain in the Wenchuan Earthquake Area Based on Plant Diversity

  • 摘要: 本文将地震灾区的崩塌山体划分为碎石坡面、巨石坡面、碎石地、洼地和沟槽地5种微生境类型。在此基础上,基于植物多样性指数,对崩塌山体不同微生境的植被自然恢复力进行了测定。结果表明,不同微生境的植被自然恢复力不同,其恢复力指数大小为:沟槽地 > 洼地 > 碎石地 > 巨石坡面 > 碎石坡面。这客观上反应了地震灾区不同生境的植被天然恢复现状,可为灾区有针对性地采取不同恢复措施提供参考。

     

    Abstract: The micro habitat of a collapse mountain in the Wenchuan earthquake area were divided into gravel slope,rock slope,gravel land,lacuna earth and groove earth in this paper. Based on the type of division of micro habitats,the resilience of natural vegetation of micro-habitats was measured by use of plant diversity. The results showed that the index of plant diversity could reflect the differences in vegetation rehabilitation of micro habitats,and the index of resilience of natural vegetation was as follows:groove earth > lacuna earth > gravel land > rock slope > gravel slope. This responded objectively to the present vegetation natural restoration in different habitats,and measured results would provide reference for taking different measures to restore the vegetation of the disaster area.
