摘要
新疆盐生植物共有331种(包括15变种7亚种),隶属于38科、125属。对新疆盐生植物区系科、属的组成和地理成分进行分析,结果表明:新疆盐生植物区系地理成分多样,区系成分以温带为主,共9科,占总科数的23.68%,除去世界分布科,所占的比例高达56.25%。在属的水平上,温带成分和古地中海成分占优势,分别占总属数的38.4%和36%。单种属、寡种属多,优势现象明显,植物区系具有强烈的旱生性和古老性,特有成分比较低,中国特有成分仅1属。这表明新疆盐生植物区系特征与本地区所处的北温带和古地中海地理位置是一致的。
There were 331 species （including 15 varieties and 7 subspecies） of halophytes in 38 families and 125 genera in Xinjiang, China, which were rich in biodiversity of halophytes. Distribution of the halophyte families and the halophyte genera in Xinjiang showed that the flora had a diverse geographical characteristic, with an overwhelming number in temperate regions, in which there were 9 families, accounting for 23.68% the total families in China. With taking off the cosmopolitan families, the left ones accounted for about 56.25% of the halophytes in China, including elements distributed in N. Temp., Old World Temp. , and Mediterranea, W. Asia to C. Asia. Temperate elements accounted for 38.4% and Tethys elements accounted for 36% at genera level. The halophyte flora in Xinjiang was dominated by single-species and few-species genera, with marked superior phenomenon. Most of the flora was xeromorphy and antiquity. The particular component took up lower percentage and there was only one Chinese endemic genus. This was consistent with the North Temperate zone and geographical location of Xinjiang.
