| 摘 要： | 本文采用Luzzy聚类分析对贺兰山的森林群落类型进行了划分,进而根据成林树种的生长、更新和Lotka-volterra竞争方程判断群落间的演替动态。共划分了3个群系,5个林型、9个林分型。青海云杉和油松是演替“顶极”的优势树种。在海拔2400m以上,群落演替的终点是青海云杉纯林,而在2400m以下则是以油松为优势种的青海云杉油松混交林。

STUDY ON THE TYPES OF FOREST COMMUNITY ON THE WESTERN SIDE OF HELAN MOUNTANI |
| |
| Abstract: | Using the Fuzzy Accumlation Analysis Method, the paper classified thetypes of forest community on Helan Mountain, and the Lotka-Volterra Eq-uation was used in predicting succession dynamics among forest communities.Three community systems, flve forest types and nine stand types were wor-ked out. It is found that Picea crassifolia and Pinus tabulaeformis are the dominantspecies of the succession climax. |
