As shown in the experimental results: as the conductor of petroleum biological degradation, the quantity of microorganism is the important factor of petroleum degradation efficiency, the huge natural capacity of microorganism in soil is its foundation of bioremediation; petroleum density in certain scope do not affect for the degradation efficiency of petroleum, and in the density of 5%, its initial degradation efficiency is higher, however after training 40 days, this kind of advantage change weak gradually, the reason may be the petroleum of high density probably having certain poison role for microorganism; the best ecological condition of petroleum contaminated soil bioremediation is that nutrition material C: N = 60, electron receives body HiOi joining quantity amount to 12 mg/g, water content is 50%, surface activator is anion surface activator of 12 Wan base benzene sulphur sour sodium; the relation of primary and secondary of factor is water content, surface activator, nutrition material and electron receiver.

试验研究结果表明：作为石油生物降解的执行者，微生物的数量是影响石油降解效率的重要因素，土壤中微生物的巨大的自然容量是其生物修复的基础；石油浓度在一定范围内对石油的降解效率并没有影响，并且在5％浓度时，其起始降解效率较高，但是到了培养40天以后，这种优势渐渐变弱，可能还是高浓度的石油对微生物有一定的毒害作用；石油污染土壤生物修复的最佳生态条件为：营养物质C：N为60，电子受体H_2O_2的累计加入量为12mg/g，含水量为50％，表面活性剂为阴离子表面活性剂十二烷基苯磺酸钠；因素的主次关系为：含水量、表面活性剂、营养物质和电子受体。
