摘要:
精河入湖口湿地是新疆艾比湖湿地的重要组成部分.本文通过空间序列代替时间序列的方法,对艾比湖精河入湖口退化湿地不同恢复期的浮游植物群落特征进行分析,结果表明,恢复早期和中期硅藻种类最多,绿藻在密度上占明显优势,恢复近期硅藻为主要优势类群.恢复早期及自然区浮游植物群落结构较为稳定,中期和近期群落结构不够稳定,易受外界环境的影响.艾比湖精河入湖口退化湿地各恢复时期浮游植物群落结构尚不完善,仍需进一步改善.在季节变化上,浮游植物种类和密度以夏季最多,春季次之,秋季最低;春、秋季以硅藻为主要优势类群,夏季绿藻为主要优势类群,蓝藻在夏季密度高于其它各季节.对各恢复期浮游植物和环境因子进行相关性分析表明,温度、盐度和总磷是影响浮游植物种类和数量的主要因素.

Abstract:
The Jinghe Estuary wetland is one of the main proportions in wetlands of Lake Ebinur, Xinjiang. By using the method of spacial investigation, phytoplankton community was analysed in the wetland of Jinghe Estuary under different restoration stages. The results indicated that in the restoration process, species number of Bacillariophyta was the most diversified in the early and middle stage of the restoration, while Chlorophyta was abundant. Bacillariophyta was dominated in the late stage of the restoration. The structure of phytoplankton community was steady in natural site and in the early stage of restoration, but that was not steady in the middle and late stage of restoration. The species composition and abundance in summer were higher than in spring and autumn. In spring and autumn, Bacillariophyta was the first dominant group in the phytoplankton community. In summer, Chlorophyta became the main dominant group. Cyanophyta in summer had a higher abundance than in spring and autumn. Canonical Correspondence Analysis of phytoplankton and environmental data for all sites showed that temperature, total phosphorus and salinity influenced on the phytoplankton community composition and abundance.
Key words:  Different restoration stages  phytoplankton  community composition  seasonal variation  wetland  Lake Ebinur  Jinghe Edtuary
