摘要:
 植被恢复过程体现在物种多样性的动态变化上,以金安桥水电站弃渣场植被恢复过程为研究对象,采用典型样方法对其植被群落恢复进行了调查,并对其植被恢复过程中的物种多样性动态变化进行分析。结果表明:2009年弃渣场植物物种由7科10个种组成,2010年增加到9科12种,2011年增加到10科14种。同时随着渣场植被恢复年限的增加,植物群落的物种丰富度指数从1.23增加到4.47,Shannon-Wiener多样性指数从0.75增加到0.81,Pielou均匀度指数从0.29增加到0.43,生态优势度Simpson指数从0.39下降到0.28。在植被恢复过程中,群落空间异质性增强,草本层和灌木层从较为均匀的状态逐渐形成镶嵌型空间格局,植物群落中各个种群的水平分布呈集群分布趋势。
Abstract:
 Dynamic changes in species diversity reflect the vegetation restoration process.Taking abandoned dreg fields in Jin’anqiao Hydropower Station as examining objects, the restorations of plant communities in the region were investigated by typical sampling method. Dynamic changes in species diversity were analyzed during the restoration. Seven families and 10 plant species were found in 2009, 9 families and 12 plant species in 2011, and 10 families and 14 species in 2012. Along with the increase of the restoration time duration, the plant community species richness index increased from 1.23 to 4.47, Shannon-Wiener diversity index from 0.75 to 0.81, Pielou evenness index, from 0.29 to 0.43, the ecological dominance simpson index from 0.39 to 0.28. Community spatial heterogeneity also increased. Herbaceous and shrub layers from more uniform state gradually presented as mosaic spatial pattern. The horizontal distribution of plant communities in various populations exhibited clustered distribution trends.
