Abstract:Based on the investigation of geochemical characteristics of main oil fields in China, Biolog and statistical approaches were employed to analyse the relationship between soil physicochemical factors and carbon metabolism of soil microbial community. The results revealed the complex effects of geochemical properties of oil fields on microbial community in the different geographic regions. The soil physicochemical properties had geographic distribution. Total nitrogen and phosphorus, available nitrogen, available copper and zinc showed positive correlation with the diversity of microbial community. Soluble salt, pH, total nitrogen, and total organic carbon were the main factors that influenced the carbon source utilization. The results indicated that the main factors which affect carbon metabolism were site-specific for the various regions. Additionally, a certain factor could exhibit different influences on the microbial community in the various oil fields. The site-specific relationships between regional soil physicochemical properties and microbial metabolism were attributed to the common effects of the geographic distribution of physicochemical properties and the regional difference of original microbial community structure.
