Petroleum is one of the most important energies and also a backbone of the national economy, with the development of petroleum industry and the increasing requirement for petroleum-product of mankind. But today petroleum pollution especially oil-polluted soil is becoming one of the most serious problems. More and more government pay great attention to it. It is imperative to deal with this problem. Bioremediation technology have many advantages such as low cost, more effective, mild conditions, no secondary pollution and friendly to environment in Solving the problem of environmental pollution.The aim of this paper was to determine the influence of soil physical and chemical properties(including pH, ammonia nitrogen, nitrite nitrogen, nitrate nitrogen, available phosphorus, total nitrogen content, total phosphorus content) and the activity of soil enzyme(including dehydrogenase, catalase, urease and amylase), which had be discussed by Suaeda heteroptera, oil-degrading bacteria and Perinereis aibuhitensis. Main results were as follows:pH rosed in oil-polluted soil. S.heteroptera, oil-D.Bac., Perinereis aibuhitensis improved the soil pH and regulated the soil pH value, and the experimental group of S.heteroptera-oil-D.Bac.-Perinereis aibuhitensiswasbetter than other groups. The content of ammonia nitrogen, nitrite nitrogen, nitrate nitrogen, available phosphorus, total nitrogen, total phosphorus were decreased inoil-polluted soil. S.heteroptera, oil-D.Bac., Perinereis aibuhitensis increased the content of ammonia nitrogen, nitrite nitrogen, nitrate nitrogen, available phosphorus, total nitrogen, total phosphorus, and the experimental group of S.heteroptera-oil-D.Bac.-Perinereisaibuhitensiswas better than other groups. The content of organic carbon was increased in oil-polluted soil. The activity of dehydrogenase, catalase and urease were decreased in oil-polluted soil. S.heteroptera, oil-D.Bac., Perinereisaibuhitensis increased the activity of dehydrogenase, catalase and urease. The change of activity of dehydrogenase, catalase, urease and amylase was S.heteroptera-oil-D.Bac.-Perinereisaibuhitensis>S.heteroptera, oil-D.Bac. >S.heteroptera >oil-polluted.
