Vertical Distribution of Physicochemical Characteristics and the Microbial Diversity in Different Spatial Sediments Samples in Lake Taihu
不同空间位点沉积物理化性质与微生物多样性垂向分布规律

The physicochemical characteristics,nutritions and the microbial community diversity of sediment core samples of three different space locations in the Lake Taihu were studied by fumigation-digestion and PCR-DGGE analysis respectively.The results indicated that below the surface of sediments Eh declined rapidly with increase of sediment depth and it was under anaerobic condition except the top layer of sediment.pH value changed silightly in the profile of sediments,which ranged from 7.2 to 7.8.TN and TP con...
