摘要
采用线路踏查和样方调查的方法，对华木莲ＳｉｎｏｍａｎｇｌｉｅｔｉａｇｌａｕｃａＺ．Ｘ．ＹｕｅｔＱ．Ｙ．Ｚｈｅｎｇ植物群落中乔木树种的重要值、物种多样性（Ｄ）、优势度（Ｃ）、群落均匀度（Ｊ）以及物种丰富度（Ｒ）等指标进行了计测，并初步分析了群落类型、结构与物种多样性指数的关系以及该植物群落的生境特点和华木莲种群特征，最后指出华木莲为中性偏阳树种，在林内天然更新困难，在现状植被中，该种群为衰退种群。
The IVI of arbor species, species
diversity index, dominance, evenness and richness of Sinomanglietia glauca Z. X. Yu et Q. Y.
Zheng communities are calculated. The preliminary studies on the correlation between
community type, structure and species diversity index and on community habitat traits and S .
glaucapopuation character were conducted. The results indicate: S. glauca is a kind of
intermediate to intolerant tree species. Being difficultly restored by natural regeneration in
forest, this population will decline under current situation.
