The Study of Soil Microorganism in Different Vegetation at the Wuliangsuhai Wetland

Abstract:

The study, by measured the number of microorganisms on the six kinds of vegetation types of WuLiangSuHai wetland, reveals that: Scirpus (Scirpus pumilus Vahl) plots, Gramineae (Phragmites australis (Cav.) Trin. ex Steud.) plots, Chenopodiacea (Suaeda glauca Bunge) plots, Zygophyllaceae (Nitraria tangutorum Bobr) plots, Artificial Tamarix plots and Artificial Elaeagnus angustifolia plots, soil microbial population and distribution is significantly different. The results show that: bacteria, Actinomycetes and Fungi are highest on the Artificial tamarix soil, are 15.6×10³CFU•g^-1, 47×10²CFU•g^-1, 43CFU•g^-1, and other microbe quantity was significantly higher than other vegetation, and the number of microorganisms in Scirpus (Scirpus pumilus Vahl) plots, Gramineae (Phragmites australis (Cav.) Trin. ex Steud.) plots and Chenopodiacea (Suaeda glauca Bunge)plots vegetation are generally low. Overall, the quantities of bacteria are the largest than the actinomycetes and fungi that was less than others quantities in variety of samples. There is a certain correlation between the number of soil microorganism and soil moisture which is one of the key factors to regulate wetland ecosystem microbial metabolic and material conversion.
