摘要:

在黄柏山林场4种典型人工林中设置样地,对林下植物组成及多样性进行研究,旨在掌握该区域森林生态系统林下植被特征。研究表明:1) 檫杉混交林林下植物丰富度最高。2)4种类型人工林林下物种Shannon-Wiener多样性指数,Simpson多样性指数和均匀度指数均存在显著性差异(p<0.05),同时各林分灌木层和草本层植被类型都呈现为中等不相似或极不相似,说明乔木植被类型对于林下物种及其多样性影响较大。在营造人工林时,树种的选择对于其可持续经营有着重要影响作用。3)4种类型人工林林下植被群落多样性指数,包括Shannon-Wiener多样性指数,Simpson多样性指数和均匀度指数均是草本>灌木。可能由于4种林分的郁闭度都较高,影响了灌木层生长,同时也为草本层喜阴植物的生长创造了一定条件。在黄柏山林场的人工林经营过程中,应适当进行抚育间伐,增加林内透光度,以利于林下植被的恢复。

Abstract:

Sampling plots were set up in the four typical plantation of Huangbaishan Forest Farm,the composition and diversity of undergrowth plant were studied to understand the undergrowth plant characteristics of forest ecosystems in the region.The results showed that:1) The plant richness of the mixed forest was the highest.2) The Shannon-Wiener diversity index,Simpson diversity index and evenness index of the four types of plantations were significantly different(p<0.05),and the shrub layer and herb layer plant types of each forest were presented as Medium dissimilarity or very dissimilar,indicating that type of arbor have a greater impact on understory species and their diversity.The choice of tree species has an important impact on plantations sustainable management.3) The diversity index of undergrowth plant community of four types of artificial forests,including Shannon-Wiener diversity index,Simpson diversity index and evenness index were herb> shrub.It may because the canopy density of the four forest stands is high,which affects the growth of shrub layer,and also creates some conditions for the growth of herb plants.In the process of plantation management of the Huangbaishan forest farm,tending and thinning should be carried out properly to increase the transparency of the forest,which is conducive to the restoration of undergrowth plant.
