中文摘要	对额济纳旗荒漠河岸林植物群落的组成、分布及对应的环境因子进行了详细的调查,调查表明:该研究区共有植物19种,分别隶属于9科15属,以豆科(Fabaceae)和柽柳科(Tamaricaceae)种最多,其次是菊科(Compositae)、茄科(Solanaceae),约占所用种数的74%,反应了干旱性大陆气候条件下旱生耐盐种类占优势的特点. 同时,应用对应分析CA(correspondence analysis)和典范对应分析CCA(canonical correlation analysis)对额济纳旗荒漠河岸林植物群落的组成与分布进行了统计分析. 结果表明:所调查的样地及样地中所出现的 19个物种,都表现出随土壤pH值变化,且变化趋势基本相同. 同时样地和物种还随着土壤含盐量的变化而呈现出有规律的变化趋势. 影响该地区植物群落恢复的环境因子主要是0-20cm土壤pH值和20-40cm土壤全盐含量;CCA排序分析将研究区的19个物种及28个样地都划分为4种类型.
英文摘要	In this paper, the desert riparian forest plant community in Ejina were studied by the correspondence analysis and the canonical correlation analysis.It is shown that there is totally19 species of higher plant belonging to 9 families 15 genera in the study area.By using correspondence analysis(CA)ordination, the relationships between the distribution of plots, plant communities and environmental factors of soil were analyzed. The result showed that the distribution of plots and plant species communities were associate with the pH gradients of soil in the first axis, and were closely related to the soil total salt gradients in second axis. Canonical correspondence analysis(CCA)ordinate analyzed the species, plots with environmental factors of soil. The result identified four species groups.
