摘要
调查发现,红松阔叶林经择伐后,与对照林分相比,不仅早春优势植物种类及其在群落中的地位有一定的改变,物种种类组成也发生了较大的变化.从物种多样性指数上看,除优势度指标经择伐林分升高外,种数、丰富度指数、Shannon-Wiener多样性指数、Pielou均匀度指数都稍低于对照林分.
Not only do species and station have some change in broad leaved Korean pine community after being thinned, through surveying and comparing with the contrast forest, but also there are many movements in species makeup. Species number, abundance index, Shannon-Wiener biodiversity index, Pielou uniformity index in the community are little lower than those of contrast forest.
