摘要: 以各个植被样地为对象,采用物种丰富度、Simpson 指数、Shannon-wiener 指数及Pielou 指数对姑婆山进行物种多样性研究;采用2×2 列联表的X2检验、Pearson 相关分析和Spearman 秩相关分析等方法对姑婆山植物群落的优势种间关系进行分析,得到如下主要结果:1) 4种多样性指数表现出相同的变化趋势,不同层次的物种多样性大小顺序为:灌木层>草本层>乔木层。2) 分层对群落优势种的种间关联性进行研究发现,群落优势种间多呈不显著关联;灌木层中显著和极显著相关的种对数最多,草本层次之,乔木层最少,这说明了姑婆山植被在主要层次上优势种的发展表现为相互竞争性呈由大变小趋势,顶极群落要么是单优群落,要么是互不相关的多优种共存群落。显然,姑婆山植被大多未达应有的顶极状态。该研究对森林资源经营、公园的建设及资源评价等方面具有一定的参考价值和意义。

Abstract: Based on the data of the sample plots,study was conducted on species diversity of plants by using species richness,Simpson index,Shannon-wiener index and Pielou index in Gupo Mountains of Guangxi province,and also on interspecific relationship between dominant species of plants by using X2 -test for the 2×2 contingency table,Pearson correlation analysis and Spearman's rank correlation analysis.The results were as follows:(1)the four diversity indexes showed the same trend and the order of different levels of species diversity is:shrub layer> herb layer> tree layer.(2)the study on the relevance of the dominant species by stratification found that the dominant species mainly have no significant correlation,shrub layer has the most kinds of species which have significant and highly significant correlation,the following is herb layer,and tree layer is the least. This shows that the development of dominant species on the main layer of the vegetation performance for the mutual competition was changed by the big-to-small trend. The climax community is either single-gifted community or more-gifted community.Obviously,the vegetation of Gupo Mountains is far from the perfect state.The above study can be of some reference value and significance to management and rational development of forest resources and evaluation of park resources and development.

Key words: Gupo Mountains, species diversity, interspecific relationship, dominant species
