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.
