摘　　要：文章通过样地调查,对国家重点二级保护植物软荚红豆群落学特征进行分析。结果表明,在2400m^(2)的样地内,有维管植物38科53属63种,群落具有明显热带性质。群落林下植被较为稀疏,灌木层的盖度只有6.20%,草本层盖度为29%。乔木层和草本层的Shannon-Wiener多样性指数和均匀度指数均高于灌木层,群落的种类和个体数目均较少且分布不均;软荚红豆种群属近期衰退远期进展型。The community characteristics of the national key second-class protected plant Ormosia semicastrata were analyzed through sample plot survey.The results showed that there were 63 species of vascular plants belonging to 53 genera and 38 families in the 2400 m^(2) sample plot,and the community was obviously tropical.The understory vegetation of the community is sparse,with the coverage of shrub layer being only 6.20%and that of herb layer being 29%.The Shannon Wiener diversity index and evenness index of tree layer and herb layer were higher than shrub layer,and the number of species and individuals of the community was less and uneven;The population of O.semicastrata belongs to the type of recent decline and long-term progress.
