Abstract:BCR method was used to study speciation of heavy metal in surface sediment of Xiaofu River. The results indicated that Cu、Cr、Pb、Ni existed mainly in sediment for crystallization and oxidation, little for weak acid extraction and reduction. The microbial community structure and its distribution characteristics in surface sediment of Xiaofu River were studied through phospholipid fatty acids analysis, which indicated that the microbial community structure was different among various sampling sites. The correlation between the heavy metals speciation and microbial structure were analyzed by various statistic methods at the same time. The results indicated the various speciations of heavy metals had different impacts on microbial community structure, in comparison with the total element content. That is, there was a negative relationship between the total content of heavy metals and biomass, fungal group, total bacterial group or the gram-positive group; but for the various speciations of heavy metals, the role metals played in influencing microbial communities was apparently complex and paradoxical.
