摘  要:
以群落组成类型资源轴上取样地段为一维资源状态,以重要值为生态位计测的资源状态指标,对木荷群落中的11个优势树种进行了生态位的计测和分析。结果表明:木荷具有较大的生态位宽度值,具有一定的稳定性;各优势树种,均表现出一定程度的对环境适应的相似性和生态位重叠。这从一个侧面反映了森林生态系统演替趋势,从而为木荷林的保护、群落结构与动态预测等提供科学依据。

摘  要:
The niche characteristics of 11 main tree populations in Schima superba forests,have been analyzed by quantitative method at the natural reserve of Wanmulin.The niche breadth,niche proportional similarity and niche overlap of main tree populations in S.superba forests were measured by taking community composition types as one-dimension resource states,and important value as the resource state descriptor of niche.The results indicated that S.superba had higher niche breadth value and would sustain stablity for a long time;all the dominant species showed similarity and niche overlap adaptable to the community environment.At a certain degree,these results showed the succession tendency of the ecosystem of the forests.The results would offer scientific theories for reserving community structure and dynamic prediction of S.superba forests.
