摘要
基于野外样方调查数据,结合遥感调查,对山西壶关太行山大峡谷风景旅游区的植物群落多样性进行研究。结果表明:研究区植物物种资源丰富,共记录野生维管植物391种,分属87科258属;采用双向指示种法将研究区植物群落分为10个群丛;受人为干扰、地形、水分条件等影响,群落的组成和结构具有一定差异性,主要表现在群落的丰富度指数、多样性指数和均匀度指数出现较大的波动,且波动趋势基本一致;研究区生态系统以森林生态系统和灌木生态系统为主,草地生态系统、农田生态系统和城镇生态系统面积较小。
Based on the field sample survey data and remote sensing survey,the plant community diversity of Taihang Mountain Grand Canyon Scenic Area in Huguan,Shanxi Province was studied.The results showed that there were abundant plant species resources in the study area.391 species of wild vascular plants were recorded,belonging to 87 families and 258 genera;the plant communities in the study area were divided into 10 clusters by two-way indicator species method;affected by human disturbance,topography and water condition,the composition and structure of the community had some differences,which were mainly manifested in the large fluctuation of richness index,diversity index and evenness index of the community,and the fluctuation trend was basically the same;forest ecosystem and shrub ecosystem were the main ecosystems in the study area,while grassland ecosystem,farmland ecosystem and urban ecosystem were smaller.
