- 摘要:
- 采用样地调查方法，对松嫩平原典型盐碱化草地及其毗邻的羊草草原以及二者群落交错区3个生境进行物种、群落特征调查，采用以二元数据为基础的β多样性指数，对植被物种更替特征进行了分析。结果表明：3个生境中盐碱化草地的β多样性最大，羊草草原最小，盐碱化草地物种替代速率最快；3个生境中盐碱化草地和交错带群落间β多样性最小，物种的相似性最大；盐碱化草地和羊草草原的β多样性最大，物种相似性最小。β多样性分析结果不能说明盐碱化草地和毗邻羊草草原在群落发生学上的关系，但在物种相似性上可以看出盐碱化草地的杂草、毒草及一年生禾本科植被的入侵对羊草草原的稳定及生产力产生了不利影响，应给予足够的重视。
- Abstract:
- The characters of species and communities in alkalized-salinized grassland,Leymus chinensis steppe and their intersectional area were investigated by sample mothod and the change characters of vegetation species in the three ecological environments were analyzed by β diversity indices based on dualistic data.The results showed that the β diversity was the most in alkalized-salinized grassland,and its species replacement rate was the fastest.β diversity and the species similarity was the most between alkalized-salinized grassland and the intersectional areas.β diversity was the most and the species similarity was the least between alkalized-salinized grassland and Leymus chinensis steppe.The result of β diversity could not reveal the relationship of communities genesis between alkalized-salinized grassland and Leymus chinensis steppe.However，the species similarity could indicated that there was bad effect of alkalized-salinized grassland on stability and productivity of Leymus chinensis steppe by the weed，poisonous grass and annual grass family species invasion.We must attach importance to this disadvantageous complexion.
