Title: β Diversity Analysis of Plant Community in Three Habitats of Songnen Plain
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.
