摘　　要：精河入湖口湿地是典型干旱区湖泊湿地艾比湖湿地的重要组成部分。本研究采用空间序列代替时间序列的方法研究艾比湖精河入湖口退化湿地恢复中植物群落的变化特征,以便诠释退化湿地恢复中植物群落演替进程和趋势。结果表明,在湿地恢复的过程中芦苇（Phragmites australis）均为优势种。退化湿地恢复的第1、3和5年时,群落内植物种分别为17、11和1种,群落盖度分别为85.98%、96.00%和100.00%,而优势种芦苇高度分别为75、85和234 cm,基本恢复到未退化自然群落水平。这说明只要水源充足,精河入湖口退化湿地经4~5年即可恢复到未退化状态。Jinghe river estuary wetland is one of the main proportion in wetland of Ebnur Lake.By using the method of space substituting time,vegetation was investigated in Wetland of Jinghe River Estuar at different restoration stages.The results indicated that Phragmites australis was the main dominant specie during the restoration process.After 1,3 and 5 years of restoration,the number of species was 17,11 and 1,community coverage was 85.98%,96% and 100%;height of P.australis was 75,85 and 234 cm,respectively.This implied that 4-5 year restoration could make the vegetation back to natural status if the water was enough.
