| 摘 要： | 通过对青藏高原祁连山东段冷龙岭南麓高寒小嵩草Kobrecia pygmaea草甸主要植物种群物候特性的观测研究,采用聚类分析和主分量排序法将小嵩草草甸26种植物种群划分为不同的物候类群.利用相关系数排序法指出了影响不同物候期的主要生态因子依次是温度、降水量和日照时间.研究结果对放牧管理具有指导意义. |

| Abstract: | The phenological characteristics of main plant populations in an alpine Kobrecia pygmaea meadow were measured and studied in this paper.The 26 plant populations in Qinghai-Tibet plateau K.pygmaea meadow were divided into different phenological groups with cluster analysis and principal component ordination.By the method of correlative coefficient ordination,the main ecological factors that influenced different phenological periods were listed as bellow: temperature,precipitation and sun shine hours,respectively.Results of this study are useful for grazing management. |
| Keywords: | Kobrecia pygmaea meadow cluster analysis principal component ordination |
