摘要
荒草坡上的草地群落是经人为破坏后演化而成的一种次生植被。该植被类型在华北地区广泛分布。本文作为荒草坡改造利用之基础研究,采用数值分类法对泰山荒草坡上的草地进行群落类型的划分,共得到12个群落类型。
The wild grass communities extensively distributed in North China is a secondary eoenotype into which the primeval vegetation was turned by artificial destroy. Now, papers studying wild grass communities by the quantitative method are rare. This paper made a cluster analysis of the wild grass communities on Mount Tai by a group-average method. At the level d=2100, we can distingush 12 coenotypes. The results also show that:1. It is practical to completely classify the wild grass communities by the numerical method.2. The major coenotypes are coincident with the traditional classification, in which there are eight communities defined as association types.
