摘  要：
1998—2012年,呼伦湖经历了连续15年的退水,在南岸形成了一个5 km×3 km的矩形退水湖岸。于2012年8月中旬对退水湖岸的植被进行调查,并利用空间代替时间的方法探讨15年来样地植被演替的序列。通过双向指示种法(TWINSPAN),在5级分类水平上将所调查的70个样方分为6组,利用去趋势对应分析(DCA)对样方排序,得到植被的演替序列为:藜科先锋群落(演替前期)→芦苇群落(演替中期)→羊草群落(演替后期)。比较各演替阶段物种多样性及组成发现:演替后期物种丰富度、均匀度和多样性明显高于演替前期和中期;物种均匀性则表现为演替中期明显低于演替前期及后期;随演替进展,多年生植物在群落中比例逐渐增加。

摘  要：
Hulun lake,the largest inland lake in Inner Mongolia,had suffered a 15-year lake retreat from 1998 to2012. The lake retreat had formed a 5 km × 3 km rectangle shape wetland. The vegetation of the rectangle shape wetland was investigated in mid-August,2012. With the help of spatial sequence instead of time successional sequence method,the succession sequence of the sample spot was revealed. After two-way indicator species analysis(TWINSPAN),70 sample plots had been divided into 6 groups in Division 5 level. Detrended correspondence analysis(DCA) was also adopted and the successional sequence was revealed as Chenopodiaceae pioneer community(first stage) → Phragmites australis community(second stage) → Leymus chinensis community(final stage). After comparing each succession stage's biodiversity index(Patrick,Simpson,Shannon-wiener and Pielou indice) and growth style,it was shown that:(1) The final stage of the succession had the highest biodiversity,evenness and richness;(2) The evenness of the vegetation dropped down a little from the first stage to the second stage,and recovered in the final stage;(3) The proportion of the perennial plant steadily increased from stage one to final stage.
