| 摘 要： | 通过对祁连山浅山区金露梅群落特征、种间关系及分布格局的分析 ,结果表明 :浅山区金露梅群落相对重要值为 10 4 .2 8% ,频度为 92 .0 0 % ,为主要优势种 ;群落内种间关系关联性不强 ,分布状况受环境条件影响而独立地分享环境资源 ,种群间相互影响小 ;经各种群分布格局的检验 ,祁连山浅山区大多数种群呈聚集分布 ,有利于种群的生存和发展。

| Abstract: | The character, interspecific relationship and distribution pattern of Potentilla fruticosa community in Qilian Mountans of Gansu Province, China, were investigated and analyzed. The analytical results showed that Potentilla fruticosa was dominant species with an important value of 104.28% and a frequentness of 93.00%. The interspecific relationship within the community was not closely interrelated. The distribution pattern of species population was affected by environmental conditions and had little interrelationship. The test of distribution patterns of all species population showed that most of the populations in Qilian Mountain area presented clustered distribution, which benefits the survival and development of population. |
