摘要
以黔中地区6种代表性马尾松群丛样地为研究对象,比较不同马尾松群丛植物群落多样性是否存在差异。结果表明,调查共记录维管植物70种,隶属于40科60属,其中被子植物57种,裸子植物3种,蕨类植物10种;依据中国种子植物科属的分布区类型的划分方法,科的分布区系以热带分布为主,属的分布区系以温带分布区系为主;不同马尾松群丛各层Margale物种丰富度指数、Shannon-Wiener多样性指数及Pielou均匀度指数具有明显差异;Bray-Curtis距离指数表明群丛Ⅲ与群丛Ⅴ的物种组成差异最小,群丛Ⅱ与群丛Ⅵ的物种组成差异最大;Jaccard相似性系数表明群丛Ⅲ和群丛Ⅴ的物种组成相似性最高,群丛Ⅱ和群丛Ⅵ相似性最低。
Six representative Pinus massoniana associations in central Guizhou were selected as the research object to compare whether there were differences in plant association diversity among different P.massoniana associations.The results showed that a total of 70 vascular plant species were recorded,belonging to 40 families and 60 genera,including 57 angiosperms,3 gymnosperms and 10 ferns.According to the division method of the distribution of family and genus of seed plants in China,the family distribution was mainly tropical,while the genus distribution was mainly temperate.There were significant differences in Margale Index,Shannon-Wiener Index and Pielou Index among different P.massoniana associations.Bray-Curtis Index showed that the species composition difference between association III and association V was the smallest,and that between association II and association VI was the largest.The Jaccard Index showed that the species composition of association III and association V had the highest similarity,while that of association II and association VI had the lowest similarity.
