选择草海湿地流域典型喀斯特森林植物群落作为研究对象,采用标准样地调查法、群落数量分析等方法,对其不同群丛、群落、层次的森林物种多样性进行分析,结果表明:(1)α多样性分析中,群丛Ⅶ(云南松-栒子+白栎—荩草+芒群丛)的Margalef丰富度和Simpson多样性最高,而群丛Ⅳ(云南松-白栎+云南杜鹃—密毛蕨+莎草群丛)的Shannon-Wiener多样性和Pielou均匀性最高;群落B(阴坡、低海拔、陡坡群落类型)的Margalef丰富度最高,群落D(阴坡、高海拔、缓坡群落类型)的Simpson多样性最高,群落A(阳坡、高海拔、缓坡群落类型)的Shannon-Wiener多样性和Pielou均匀性最高。(2)β多样性分析中,群丛Ⅰ(云南松+马缨杜鹃-矮杨梅-野鸭茅群丛)—Ⅱ(华山松+云南松-矮杨梅+云南杜鹃-密毛蕨+白茅群丛)的β多样性最高;群落A(阳坡、高海拔、缓坡群落类型)-D(阴坡、高海拔、缓坡群落类型)的β多样性最高。
The typical karst forest community in Caohai wetland was selected as the research object and the forest species diversity of different communities, communities and levels was analyzed by standard sample survey and community quantity analysis. The results showed that: (1) In the α diversity analysis, the Margalef abundance and Simpson diversity of the cluster Ⅶ (Pinus yunnanensis - Prunus humilis + Quercus mongolica + mangrove group) were the highest, but the cluster Ⅳ (Pinus yunnanensis - The highest Shannon-Wiener diversity and the highest Pielou homogeneity among the two groups; Margalef abundance was the highest in community B (shady slope, low altitude and steep slope communities), while community D (shady slope, high altitude and gentle slope Community type), Shannon-Wiener diversity and Pielou evenness of community A (sunny slope, high altitude and gentle slope community type) were the highest. (2) In the β-diversity analysis, the cluster Ⅰ (Pinus yunnanensis + Lysimachia rhododendron-Ardisia mandshurica) -Ⅱ (Pinus armandii + Pinus yunnanensis-Aristolochia yunnanensis + Yunnan azalea- ) Had the highest β diversity; community A (sunny slope, high altitude, gentle slope community type) -D (shady slope, high altitude, gentle slope community type) had the highest β diversity.
