| 摘 要： | 本文采用数学分析的方法，对海北高寒草甸生态系统开放实验站地区的植物群落进行了数量分类和排序。结果表明：当相关系数R=0.85时，64个样地群落可以划分为23个群落类型，各群落类型的层次结构、种类组成、生态条件以及地理分布上均有明显特点。排序结果证明：群落类型的排序坐标分别与海拔、土壤温度和土壤湿度之间有密切的关系。

| Abstract: | Quantitative classification and ordination were applied to the plant communities in the region of Haibei Alpine Meadow Ecosystem open experimental Station. The results have shown that: when correlation coefficient R=0.85, sixtyfour plots were divided into twenty-three types of plant communities every type of which has distinctive characteristics in structure, species composition, ecological conditions and geographical distribution. The results of ordination showed that coordinates of plant communities have close relation with altitude, soil temperature and soil potential. |
