| Abstract: | The typical steppe,meadow steppe and three transition zones in the middle of Hulun Buir were taken as the research objects,using the field community survey method,set up five experimental sample plots,the meadow steppe(A),typical steppe(C)and transition zone(B1,B2,B3),randomly took 15 quadrats of 1m×1m from each plot,aboveground biomass and species composition were measured,the important value、diversity index and community similarity index were analyzed.The results showed that,(1)From the meadow steppe to the transitional zone and then to the typical steppe,the species decreased gradually,and the importance value of the constructive species fluctuated greatly,Carex duriuscula and Artemisia gradually appeared;(2)The similarity between each two sample plots were:B1 of the transition zone and the meadow steppe A>B3 of the transition zone and the typical steppe C>B2 of the transition zone and the typical steppe C>B3 of the transition zone and the meadow steppe A>B1 of the transition zone and the typical steppe C>B2 of the transition zone and the meadow steppe A;(3)The species diversity showed:the highest value of the Simpson diversity index(D),Shannon-wiener diversity index(H′)and Margarlef richness index(Ma)were appeared in meadow steppe,and the lowest were in typical steppe samples;But the Pielou uniformity index(Jp)was the highest in the transition zone B3,and the lowest in the transition zone B1. |
