乌梁素海湿地过渡带土壤微生物类群数量与分布特征
Soil Microbes and Their Distribution in Wuliangsuhai Wetland
摘要
Abstract
Wuliangsuhai wetland is the largest wetland on the same latitude in the world, and plays important roles in maintaining ecological functions of its surrounding area. In the present study, community structure of bacteria, fungi and actinomycetes were profiled in three types of wetland soils and a farmland soil grown with Phragmites australis, Suaeda salsa, Nitraria tangutorum and Helianthus annuus, respectively, from Wuliangsuhai wetland. Bacteria were dominant, while fungi minor in all soils. Quantities of microorganisms were different under differ-ent types of plants. The largest number of bacteria was found at Phragmites australis soil of Xiaohekou site, whereas fungi and actinomycetes were the most abundant in Nitraria tangutorum soil. Farmland soil had the highest spore-forming bacteria. The results indicate that the dis-tribution of microbes in soil is closely related with vegetation type and soil nutrients.关键词
