| 摘 要： | 本文对松嫩平原碱化草甸6种单优盐碱植物群落土壤中有发芽力的种子贮量及其物种多样性进行了比较分析。虎尾草群落、角碱蓬群落、翅碱蓬群落3种一年生植物群落所具有的共同特征，表现为种子库存量大，优势种的种子数量占绝大多数，种子库的物种多样性指数相对较小。星星草群落和獐毛群落这两种过渡性的多年生群落，地上优势种均为种子库中的优势种，种子库的物种多样性指数趋于中等。羊草群落与其他演替阶段的群落相比，种子库存量最小，种子库的物种多样性指数最大。

| Abstract: | The storage of viable seeds and the species diversity in the soil of six salinealkali communities dominated by one species in the alkalized meadow in the Song-Nen Plain of China are comparatively analyzed in this paper.The common feature of the three communities dominated by Chloris virgata,Sucda corniculata,and S.heterotera was that they had large seed banks,of which the majority was composed of the dominant species,and had lower species diversity index,The transitional communities dominated by Puccinellia tenu-iflora and Aeluropus littoralis var.sinensis,respectively,showed medium seed bank and species diversity.The dominant species in the seed banks were the same as the aboveground dominant species in tkese two communities.The Aneurolepidium chinense community differed from other communities of di-fferentiating successional stages,in that it had the slnallest seed bank,and highest species diversity. |
