艾比湖湿地自然保护区典型群落物种多样性分析

Study on the species diversity of typical plant communities in Ebinur Lake Wetland Nature Reserve

采用Shannon-Wiener和Simpson物种多样性指数,Margalef和Gleason丰富度指数,均匀度指数和生态优势度指数对艾比湖湿地自然保护区典型群落物种多样性进行分析研究。结果表明:植物群落在垂直结构上的多样性分布是灌木和乔木的物种均匀度、多样性和丰富度指数的变化趋势均大于草本,而生态优势度指数则与其相反,表现出单一的植物群落结构,说明艾比湖自然保护区典型群落在多个层次上物种的数量和分布与该地环境条件成正相关,即该区植物种类少、盖度低,生物资源丰富度十分匮乏。

Using Shannon - Wiener and Simpson＇s index of species diversity,Gleason and Margalef richness index, Evenness index and Ecological dominance index to analyze the species diversity of the typical plant community in Ebinur Lake Wetland Nature Reserve. The results show： In the vertical structure, the distribution of the plant diversity is that the uniformity, diversity and richness indexes of the arboreal and shrub species are greater than those of the herbal, but the ecological dominance index is oppositive. The overall trend shows a single plant community structure, this points out that in a number of levels, the quantity and distribution of the typical community in Ebinur Lake Wetland Nature Reserve are positive correlation with the environmental conditions. It is generally fewer plant species, low coverage and the very short supply abundance of biological resourcds in this region.
