摘要: 在对雾灵山自然保护区9个代表林分物种多样性详细调查的基础上,运用多种群落多样性指数对其群落的物种多样性进行分析。结果表明:各群落在乔木层、灌木层和草本层的物种多样性指数均呈现出一定的差异。乔木层物种多样性、Pielou均匀度指数和丰富度指数变化趋势呈一致性。灌木层和草本层均出现不一致性,主要是因为各林分起源不同,天然林群落是由处于不同发育阶段、具有不同组成结构、大小不同的众多斑块镶嵌而成的,是一个健康的生态系统。人工林群落的生物多样性很低,使人工林群落无论在活力、组织结构和恢复能力等诸方面,均表现出系统的不健康特点。

Abstract: The forest has been seriously destroyed in Wulingshan Nature Reserve area. A total of 9 plots were chosen for this study.By comparing species diversiey factors ,the differences among these plots and their correlation with the environmental factors were disclosed ,The results showed that the diversity index of tree layer ,shrub layer and herb layer among various plots was somewhat different. This trend was consistent with the changes of the species diversity and evenness index and species richness index in tree layers.There were differences in the shrub layers and herb layers. The key was the different origins of the forests.Natural forest communities at different developmental stages with the structure of the different components of different sizes from large patches of the mosaic, are a healthy ecosystem. Plantation community with low biological diversity in terms of community vitality and recovery capacity of the organizational structure demonstrates characteristics of an unhealthy system.

Key words: Wulingshan, species diversity, forest ecosystem health
