| 摘 要： | 以东天山喀尔里克山北坡-淖毛湖为研究区,探讨了该区山地-荒漠生态系统的植物种类组成、植被类型及群落物种多样性特征.结果表明:该区共有高等植物33科93属133种,植物生活型组成以草本植物居多.群落物种多样性测度指数的主成分分析结果显示,物种丰富度指数(R)、Pielou均匀度指数(Jsi)、Shannon-Wiener多样性指数(H)和Simpson优势度指数(C)能很好地描述群落结构和组成特征.其中,多样性指数、均匀度指数和丰富度指数的变化趋势基本一致,优势度指数则和前三者呈负消长的关系.随着海拔升高,群落物种多样性指数、丰富度指数和均匀度指数变化均呈现单峰分布格局,即植物群落的物种多样性在山前荒漠生态系统和高海拔山地生态系统中较低,而在中海拔地区达到最大.

| Abstract: | Based on the data from 22 sample sites,species diversity of plant communities in the northern slopes of Karlik Range-Naomaohu were discussed. The Karlik Range is situated in the eastern section of the Tianshan Mountains,and the Naomaohu is located between the Altai Mountains and Tianshan Mountains. The research on the botany has not been found in this region yet. Applying the analytical method of species diversity indices,the composition,species,and diversity of the vegetation in the study area are discusse... |
