摘　　要：近年来,我国经济与科技的发展也推动了石油产业迅猛发展,随着对石油资源的开发利用,引发的土壤石油污染问题尤为严重,既危及到农作物生长,又威胁到生态环境。阐述了土壤石油污染的成因及危害,列举了几种土壤石油污染修复技术,通过以某油田为研究对象展开了相关试验,着重研究了土壤石油污染的修复效应。结果表明:土壤中石油污染物含量越高,植物发芽率、株高和生物量的下降趋势越明显,对比发现黑麦草和高羊茅具有较强的耐受力和修复潜力,而紫花苜宿和沙打旺受石油污染的影响最为直接。就不同植物对土壤石油污染的修复效应而言,6种植物均表现出促进土壤修复的作用,在0.5%污染程度下,柠条和沙打旺更适用,在1%污染程度下黑麦草、高羊茅、冰草更为适用。据此,结合试验结果,提出了一些优化建议及策略,可为相关研究提供借鉴。In recent years,the development of China's economy and science and technology has promoted the rapid development of the oil industry.With the development and utilization of oil resources,the problem of soil oil pollution is particularly serious,which not only endangers the growth of crops,but also threatens the ecological environment.This paper first describes the causes and hazards of soil oil pollution,lists several soil oil pollution remediation technologies,and focuses on the remediation effect of soil oil pollution through relevant experiments in an oil field.The results showed that the higher the content of oil pollutants in soil,the more obvious the downward trend of plant germination rate,plant height and biomass.It was found that ryegrass and tall fescue had strong tolerance and remediation potential,while Alfalfa and Astragalus adsurgens were most directly affected by oil pollution.In terms of the remediation effect of different plants on soil oil pollution,the six plants all showed the role of promoting soil remediation.At 0.5%pollution level,Caragana korshinskii and Astragalus adsurgens are more suitable,and at 1%pollution level,ryegrass,tall fescue and wheatgrass are more suitable.On this basis,combined with the test results,some optimization suggestions and strategies are proposed,which provides reference for relevant research.
