汶川地震对两种气候区植被恢复群落特征的影响
Community characteristics of vegetation restoration in 2 different climate areas of Wenchuan earthquake affected region
摘要
Abstract
In order to understand the characteristics of vegetation restoration community in 2 different climate zones ( semi-arid dry hot valley climate zone and subtropic humid monsoon climate zone) in Wenchuan earthquake affected region, by the field survey and analysis in the laboratory, species composition, important value and species diversity of vegetation restoration communities in different plots were analyzed.The results showed that:(1) the species number of tree, shrub, and grass had great difference between 2 climate types.Fern and non-annual herb were higher in subtropic humid monsoon climate than that in semi-arid dry hot valley except tree and shrub.As the effects of earthquake and restoration measures, arbor and shrub dominated in the destroyed and treated area which were different with undestroyed area, and destroyed and untreated area which were dominated by grass.(2) Species distribution was not even in all plots, especially in recovery area that was dominated by human-planted shrub and trees, causing the variation of important value.( 3) The Shannon-wiener index in both climate zones showed a trend of undestroyed area >destroyed and treated area >destroyed and untreated area, but the diversity index of herb was lowest in destroyed and treated area and highest in destroyed and untreated area.The survey and analysis found artificially planting shrub and arbor was helpful for species become rich in the earthquake affected area and promote the development of vertical structure of plant community.关键词
