四川道路边坡自然恢复的植被多样性研究
Study on Vegetation Diversity of Road Verge after Natural Restoration in Sichuan Province,China
摘要
Abstract
In this paper,we investigated road verge vegetation to study the plant diversity after natural restoration with line transect surveys in Sichuan Province.There are 66 families and 159 genera of 190 plant species,including 81 species of shrubs,109 species of herbs.Margalef richness index,Shannon-Wiener diversity index,Simpson index,Pielou evenness index and Cody diversity index were selected to examine the relationships among plant community diversity,slope,aspect,elevation,recovery duration.The results showed that habitats with slope from 45° to 60°,the south faced slope,the elevation of 500～700 m and the recovery duration10 years slope had higher community diversity,contributing to the vegetation restoration.However,habitats with slope60°,the north faced slope,at an altitude700 m,and the recovery duration10 years had the lower diversity.In addition,Cody index was used to analyze β-diversity along the slope and elevation environmental gradient,which was consistent with the results of α-diversity.During the course of ecological restoration of road verge vegetation in this region,habitats with lower diversity resulted from adverse environmental factors,well-adapted species,higher species richness and density,with additional artificial interferences should be adopted to enhance the community diversity.关键词
