Abstract

Abstract: The principal composition analysis (PCA) was used to study the multivariate characteristics of desert vegetation in Junnger Basin. According to the average cover and the frequency of plant species occurrence, Haloxylon ammodendron, Reaumuria soongorica, Nitraria sibirica, Ceratocarpus arenarius and Horaninowia ulicina are the most important plant species in the Junnger desert vegetation and regional plants. Ephemeral plants also represent a very important constituent of Junnger desert vegetation because they perform a great rare value in multivariate analysis. The results of multivariate analyses identify with the previous researches, and offer valuable data for future research on the succession of plants of the Junnger desert vegetation.

Key words: Junnger basin, Desert vegetation, Multivariate analysis, Ordination

摘要： 用主成分分析排序法分析准噶尔盆地沙漠植被的多元特征。结果表明:根据植物种的盖度和出现频率认为,梭梭(Haloxylona mmodendron)、琵琶柴(Reaumuria soongorica)、西伯利亚白刺(Nitraria sibirica)、角果藜(Ceratocarpus arenarius)和对节刺(Horaninowia ulicina)是该地区最为重要的沙漠植被组成成份及地带性植物;一年生植物表现出较为重要的特征,是沙漠植被中重要的组成成份;与前人的研究成果一致,可为准噶尔沙漠植被的演替提供有价值的资料。
