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。
The results showed that not only the species of early-spring dominant plants but also their position in the community had some changes compared with the control stand after the selective cutting of the Korean pine broad-leaved forest, the species composition also changed greatly. Species diversity index showed that the species number, richness index, Shannon-Wiener diversity index and Pielou evenness index were all slightly lower than the control stand except for the dominance index increased by selective cutting.
