| 摘 要： | 采用灰色关联度法分析了蓖山丹霞山体不同植物群落物种Simpson指数和Sheldon指数的系数和关联度。结果是：①在同一生长型（乔或灌或草层），群落之间其Simpson指数和Sheldon指数的关联系数变化规律不明显；②在丹霞地貌区，孤立分布的丹霞地貌形成生态隔离而使丹霞山体出现孤岛生境，造成植被的间断分布，群落间的关联系数和关联度变化规律不一致；③灰色关联分布是样地较少时分析植物群落物种多样性的有效方法。

| Abstract: | The Simpson exponent and Sheldon exponent of different plant community species in Langshan Mountain were researched u- sing gray relevancy analysis method. The results were showed as follows ： （1） In the same growth model, the change of the Simpson exponent and Sheldon exponent were not obviously in pattern. （2） In Danxia geomorphie zone, the danxia mountain consisted of isolate island territory because of the ecological isolation. The diversification disciplinarian of relating degree and relating coefficient of community were disaccord. （3） The gray relevancy analysis was an efficient method of analyzing diversity of plant community when the samples were less. |
