摘要
〕新疆天山１号冰川附近高寒草甸上的高山红景天种群的分布格局为集团分布，符合ｎ＝２的奈曼分布型，此格局的形成主要是靠有性生殖（即种子繁殖），营养繁殖对其形成只起间接的作用。其种群数量和分布格局的变化将会对高寒草甸生态系统的稳定性产生影响。
The study was made near the Glacier No.1 in the Tianshan mountains of Xinjiang.The population distribution pattern in Rhodiola coccinea was Neymen distribution(n=2) of contagious distribution.The formation of this pattern mainly resulted from it's sexual reproduction.The vegetative propagation only produced an effect to this pattern indirectly.The changes on quantity and population distribution pattern in Rhodiola coccinea will take a great deal of influence on ecosystem of alpine meadow.
