| 摘 要： | 在2×2联列表的基础上,应用χ2检验、联结系数、spearman秩相关,检测古尔班通古特沙漠植物种间关系,以期分析各物种在沙垄不同地貌部位的变化异同及种群稳定性。结果表明:①灌草两层共435个种对中,联结程度达到显著的种对较少；极显著的有15种对,显著的有22种对,其余398种对联结程度不显著。②按组间联系及种间的正负关联性,将30个主要优势种划分为5个生态种组。灌木层植物可分为3个种组:Ⅰ.白梭梭、沙拐枣；Ⅱ.蛇麻黄；Ⅲ.绢蒿；草本层分为两个种组:Ⅰ.苔草、尖喙牻牛儿苗、条叶庭芥、角果藜；Ⅱ.对节刺、沙生千里光、东方旱麦草；并提出各生态种组物种的分布特征。

| Abstract: | In order to analyze the spatial change of species in different positions of dunes and the stability of Haloxyon persicum population,χ2 interspecific association test,association coefficient,and Spearman rank correlation coefficient were used to determine the interspecific associations in the Gurbantunggut Desert based on the 2×2 contingency table.The results are obtained as follows: 1) Among the 435 species pairs from both shrub and herb layers,few show significant χ2 association(P<0.05): 12 pairs show highly significant association(P<0.01),15 pairs show significant(P<0.05),and the other 398 pairs show non-significant associations.2) According to interspecific association and species correlation,the 30 dominant species were clustered into five ecological groups: 3 are from shrub layer,they are Group Ⅰ—Haloxyon persicum+Calligonum leucocladum,Group Ⅱ—Ephedra diotachya,and Group Ⅲ—Seriphidium terraealbae;2 from herb layer,Group Ⅰ—Carex physodes+Erodium oxyrrhynchm+Alyssum linifolium+Ceratocarpus arenarius.Group Ⅱ—Horaninowia ulicina+Senecio subdentatus+Eremopyrum orientale.The species distribution characters of these ecological groups were also analyzed in this paper. |
