| 摘 要： | 应用作者提出的植物群落异质性指数,分析了甘南亚高山草丹上鼢鼠土丘植被演替趋同发展过程;发现在演替初期群落异质性稳定地下降,而后期又开始上升;说明了在早期演替群落趋同发展,而在后期又开始有离散化的趋势;对本文所得结果,作者进行了讨论.

| Abstract: | Adopting the heterogeneity index(HI)of plant community offered by the authors,this paper analyses the developmental process of successionalconvergence of zokor's mounds in the area of subalpine meadow in thedistrict South of Gansu Province.we find that in the early stages of thesuccession HI decreases gradually,while in the later stages HI increasesagain.The results suggest that early succession converges and latersuccession tends to diverge. |
