格氏栲林群落物种多样性研究

Studies on the Species Diversity of Castanopsis kawakamii Forest Community

对格氏栲天然林群落的物种多样性和物种重要值进行调查分析 ,初步探讨格氏栲群落乔木树种的演替趋势。格氏栲林群落物种多样性Simpon指数和Shannon -Wiener指数分别达 0 95 8和 3 495 ,显示该群落是相对稳定性较大的群落 ,群落物种多样性丰富 ;群落重要值分析表明格氏栲是该群落的主要优势种。群落演替趋势说明 ,要加强保护格氏栲自然更新 ,通过种子繁殖和萌蘖等方式互补 ,从而使其成为稳定的群落。

Through investigating the natural forest of Castanopsis kawakamii,this articleanalysed the community species diversity and species important value to preliminarily approach the successional tendency of arbor species of C.kawakamii community.The Simpon index and Shannon-Wiener index of the community species diversity of C.kawakamii forest were 0.95g and 3.495,respectively,which indicated that the relative stability of the present community was comparatively high and the species diversity of the community was rich.The analysis of the community important value showed that C.kawakamii was the main dominant species in the community.The community successional tendency revealed that we should intensify the protection of C.kawakamii natural regeneration to make the community stable through the complementation of the modes of seed breeding,sprouting,etc.
