| 摘 要： | 在群落调查的基础上，对贺兰山高山草甸进行数量分析。主要的结果如下：（1）贺兰山高山草甸可分为三个群系，分别为珠芽蓼群系、高山嵩草群系和矮嵩草群系，而高山嵩草群系和矮嵩草群系可进一步划分为两个亚群系，不同群系（或亚群系）的群落结构和环境特征之间存在显著的差异；（2）高山嵩草群系和矮嵩草群系之间的界限约为海拔3200m，而珠芽蓼群系主要分布于研究区的偏阴坡，与海拔关系不大；（3）14个频次大于50％的物种在排序图上的空间分布反映了这些物种最适宜生境的位置，而且与群落类型的空间分布一致。 |

| Abstract: | Few researches had been conducted on Kobresia meadow in Mt. Helan region. Based on investigation of sampling plots, alpine meadow in Mt. Helan was quantitatively analyzed. Some primary results were obtained. Three vegetation formations could be distinguished from alpine meadow in study area, that is, Form. Polygonum viviparum, Form. Kobresia pygrnaea and Form. K. hurnilis. Both of Form. K. pygmaea and Form. K. hurnills could be divided into two Sub-Formations further. Significant differences of community structure and environmental features were existed among different plant Formations or Sub-Formations. In study area, the altitudinal boundary between Form. K. humilis and Form. K. pygrnaea was about 3200 meters above sea level, and Form. P. viviparurn was prone to northern slope, with little relation to elevation. Spatial distribution of 14 species, which frequency of existence was beyond 50%, in two-dimensional ordination plot reflected their most suitable habitats, and those distributions were consistent to the distributions of different plant Formations in study area. |
