中文摘要：
利用TAMⅢ等温微量量热仪研究不同浓度的石油污染对土壤微生物活性的影响。对大港油田不同石油污染程度的土壤样品（3683-5-1、西51-5、西15-14和8-13-6H-1）以及实验室配置的短时间内石油污染土壤（空白、0.5%、1.5%、2.5%和4.0%）进行了微量热检测。含油量升高,总放热量升高,生长速率常数降低,峰值功率先升高后降低,达到最大峰值功率的时间随着含油量的升高而延长。结果表明,石油污染会影响土壤微生物的活性,并且在低浓度时促进微生物的生长,石油浓度高时会抑制土壤中微生物的生长代谢。
英文摘要：
TAM Ⅲ multi-channel calorimetry was applied to study the effect of different concentrations petroleum on soil microbial activity.The soils samples from different wells of Dagang Oil field（3683-5-1,West 515,West 15-14,8-13-6H-1） were detected.At the same time,serials of soils with different concentrations of petroleum（control,0.5%,1.5%,2.5%,4.0%） were prepared to study their short-time effect on microbial community activity.As the oil content increased,the total heat evolution increased,the microbial growth rate constant decreased,the peak-heat output powers increased first and then started to decline when reached a certain concentration,and the times of the peak delayed after crude petroleum added.The results indicate that the soil microbial activity was promoted at the lower concentration but then inhibited accordingly with increasing concentrations of petroleum.
