摘要
常绿阔叶林是浙江省的地带性植被,在维护区域生态系统功能等方面起着重要作用.综合该省若干保护较好地区的样方资料,采用多项指标进行了物种多样性的测度,表明浙江省保护较好的常绿阔叶林区域是我国中亚热带东部物种多样性较高的区域之一,自然环境、群落小环境和人为干扰是影响多样性大小的重要因素,常绿阔叶林中的珍稀物种需要给予更多的关注与保护.
Evergreen broad-leaved forests are the zonal vegetation of Zhejiang, and they are vitally important for maintaining the function and stability of the ecosystems in that region. By synthesizing the information of the sample plots in publications, the species diversity was calculated with species richness, Shannon-Wiener＇s, Simpson＇s indices and Pielou＇s evenness indices. These data illustrate that the regions in Zhejiang in which evergreen broad-leaved forests are well-protected are the regions which hold higher species diversity in the middle subtropical area of East China. Natural conditions, microenvironments in communities and human-induced disturbance are the main factors which affect the species diversity. Much more concern and protection should be given to the rare and endangered species in evergreen broad-leaved forests.
