| 摘 要： | 2010年7月在西鄂尔多斯国家级自然保护区运用样方法对沙冬青群落内主要伴生种种群进行样方调查后,运用种间关联性、显著性检验（X2）、关联程度、联接系数等方法进行了分析研究。研究表明：沙冬青群落种间关联性为显著正关联,物种之间关联程度、共同出现概率较高,轻度和高度种间负联接的对数比正联结占优势;群落正在由沙冬青单优种向沙冬青—霸王共优种群落演替。

| Abstract: | In July,2010,after the investigation on main companion species in Ammopiptanthus mongolicus community by use of quadrat sampling method,the interspecific association,significance test（X 2）,degree of relatedness and association coefficiency have been analyzed.The results show： the interspecific association of Ammopiptanthus mongolicus community is significient positive association,the degree of relatedness and co-appearance probability among species are higher,logarithm to light and high interspecific negative association takes dominance than positive association,and the community is succeeding to co-dominant species from monodominant community of Ammopiptanthus mongolicus. |
