摘要: 在多元划分的基础上,使用典型对应分析(CCA)对乌鲁木齐地区的灌木物种进行排序,研究影响该地区灌木群落类型的因素,以及与主要环境因子的关系,结果表明: ① CCA排序图较好地显示了灌木群落与主要环境因子的相关性,并指示了灌木物种的生境梯度;② 海拔较土壤环境因子对灌木群落分布的影响更显著;③ 土壤环境因子中,不同土壤层次处土壤全盐含量对灌木群落的分布有重要的作用,全磷含量的影响最小;④ 研究区灌木群落更易生活在粗质土壤中;⑤ 表层土壤性质决定了山地灌丛及灌木荒漠的分布格局,中-浅层和深层土壤的影响较小。

Abstract: Based on the TWINSPAN classification,the relationship between the shrub communities in Urumqi and the main environmental factors were analyzed by CCA. The results are as follows: ① CCA biplots revealed that the distribution pattern of shrub communities was most strongly associated with environmental factors,and they reflected clearly the habitat gradient of shrub communities; ② The effect of elevation on the distribution of shrub communities was more significant than that of soil environment factors; ③ In the soil environment factors,the effect of total salt content on the distribution of shrub communities was the most important,and that of total phosphorus was the lowest; ④ The shrub communities were likely to survive in coarse soil; ⑤ The distribution pattern of mountainous shrubbery and shrub desert was strongly affected by the topsoil properties,and the effect of shallow-moderate and deep soil properties was low.

Key words: shrub community, soil environment, CCA, Urumqi
