| 摘 要： | 本文应用DCA、CCA及DCCA排序技术对新疆呼图壁盐化草甸群落进行了分析。分析中选取了地下水位、粘土层出现深度、粘土层厚度、地下水pH值及地下水矿化度5个环境因子；同时为了分析空间格局对植被分异影响的大小，建立了样地空间坐标矩阵。结果表明：地下水位和地下水的pH值是引起植被分异的两个主要因素，空间格局对植被分异的影响大于环境因子对植被分异的影响。

| Abstract: | The salty meadow community of Hutubi, Xinjiang was analyzed by DCA,CCA and DCCA.The environment factors include level of underground wa-ter, depth of the clay layer,thickness of clay layer,pH value of undergro-und water and mineral contents of underground water.The spatial coordinatematrix was established in order to partition out the effect of the spatial pa-ttern to vegetation variation. The results show that the level of underground wat0r and the pH value of the underground water are two main factors affecting the vegetation variation; the effect of spatial pattern to vegetation variation is larger than that of environmental factors to it. |
