摘 要：
通过连古城自然保护区苏枸杞群落的结构特征分析,表明连古城自然保护区内,苏枸杞种群的重要值在灌木、半灌木种群中远远大于其他亚优势种群,达到81.90,在群落中的地位和作用非常突出。通过方差/均值比率法和t检验分析,表明其分布方式为典型的集群分布,在群落中占有显著的地位,起着决定性作用;在种群年龄结构上,整体呈半哑铃状锥体,冠幅在0~300 cm2的幼体数量较少,冠幅在400~500 cm2的成年个体数量较多,大多数处在生殖盛期,而且变化趋势比较稳定。

摘 要：
Through the analysis of Lycium ruthenicum community structure character in Minqin Liangucheng Na-ture Reserve.The results showed: the important value of Lycium ruthenicum in Minqin Liangucheng Nature Reserve was 81.90,it was bigger in shrub and semi-shrub communities than in other sub-dominant communities,the status and the effect were very prominence.Meanwhile,through the analysis of V/m and t-test,the results showed that the distri-bution pattern was typical contagious distribution.It occupied remarkable position and had decisive effect in this com-munity;it showed half-dumbbell shape on the whole on the age structure.The quantities of larvae which crown width of 0~300 cm2 were lessa,nd the adult individuals which crown width of 400~500 cm2 were more.A lot of them were at re-productive peak period and their trend was more stable.
