本文对石油烃类降解的机理进行了探究，对石油烃类降解的概念进行了详细定义和内涵的赋予，对石油烃类降解的方法种类进行了分类：物理降解、化学降解、生物降解，及物理–化学降解、物理–生物降解、生物–化学降解、物理–化学–生物复合降解等，并对每种降解的机理进行了剖析，指出了优点与缺点，对这些石油烃类降解的方法与技术的应用进行了推广。最后，指出了当前石油烃类降解机理的研究不足，及应该加强探究和填补空白之处，肯定了当前已有的研究成绩，展望了研究的未来，特别强调石油烃类降解功效的影响因素和指标的调查与筛选及综合判断指标和评价体系和模型的构建的重要性与迫切性及可行性。
The mechanism of the degradation of petroleum hydrocarbons is explored, the concept of petro-leum hydrocarbon degradation is defined in detail and connotation is given, and the methods of petroleum hydrocarbon degradation are classified: physical degradation, chemical degradation, biodegradation, and physical-chemical degradation, physical-biodegradation, bio-chemical deg-radation, physical-chemical-bio combined degradation, etc. This paper analyzed the mechanism of each degradation, and pointed out the advantages and disadvantages, and analyzed the methods and technologies for the degradation of these petroleum hydrocarbons. The application would be promoted. Finally, it would be pointed out that the current research on the degradation mechanism of petroleum hydrocarbons was insufficient, and we should strengthen the exploration and fill in the gaps, affirm the current existing research achievements, look forward to the future of the research; and particularly emphasize the factors and factors affecting the degradation efficiency of petroleum hydrocarbons. The importance, urgency and feasibility of the investigation and screening on these influencing factors and indicators of the degradation of petroleum hydrocarbons as well as the construction of the comprehensive evaluation index and evaluation system and model had been emphasized.
