Studies on Community Diversity of Spore-Forming bacteria at Soil of Swamping Wetland in WuLiangSuHai
This study used plate count method to analyze the composition of the Spore-forming bacteria community in the soil in swamping wetland, alkaline land, and desert belt, all of which grow in the upstream, midstream and downstream of swamping wetland of Wuliangsuhai. In this process, the Shannon-Wiener index, Simpson index were used to analyze the index of diversity (H), the index of evenness (J), the index of richness (R) and the index of dominance (D) of the Spore-forming bacteria community. The results showed that: the diversity index of in soil of the swamping wetland and desert belt was the highest in the midstream, second in the upstream, and lowest in the downstream; that in soil of the alkaline land was the highest in the midstream, second in the downstream and lowest in the upstream, and showed significant differences between in the midstream and downstream and in upstream; that in soil of the desert belt showed significant differences between in the upstream and downstream and in midstream; in the same area, in the desert belt soil of Spore-forming bacteria more than swamping wetland and alkaline land.
