中俄原油管线大兴安岭多年冻土地温分布的特征研究开题报告摘要中俄原油管线是连接中俄两国境内的一条重要的能源运输通道。其经过大兴安岭地区时需要考虑多年冻土的影响，因此在设计和建设过程中需要进行多年冻土的研究。本文将以大兴安岭地区为研究区域，分析该地区多年冻土地温的分布特征，为中俄原油管线的设计和建设提供科学依据。本文首先简要介绍了大兴安岭地区的地理特征和多年冻土的基本特征，然后对该地区的气候条件、地形条件、土壤质地等因素进行了分析，探讨了这些因素对多年冻土地温分布的影响。接着通过分析该地区地下温度场数据，得出了多年冻土的深度和分布情况。最后，结合中俄原油管线的设计和建设，提出合理的多年冻土保护措施。本文的意义在于通过深入研究大兴安岭地区多年冻土地温的分布特征，为中俄原油管线的设计和建设提供科学依据，为环境保护和节能减排做出贡献。关键词：中俄原油管线；大兴安岭；多年冻土；地温分布特征；保护措施AbstractTheChina-RussiaoilpipelineisanimportantenergytransportationchannelconnectingChinaandRussia.WhenpassingthroughtheGreatKhinganMountainsarea,theimpactofpermafrostneedstobeconsidered.Therefore,thestudyofpermafrostisnecessaryinthedesignandconstructionprocess.ThispaperwillanalyzethedistributioncharacteristicsofpermafrosttemperatureintheGreatKhinganMountainsarea,inordertoprovidescientificbasisforthedesignandconstructionoftheChina-Russiaoilpipeline.ThispaperfirstbrieflyintroducesthegeographicalfeaturesoftheGreatKhinganMountainsareaandthebasiccharacteristicsofpermafrost,andthenanalyzestheclimateconditions,terrainconditions,soiltextureandotherfactorsinthisarea,exploringtheimpactofthesefactorsonthedistributionofpermafrosttemperature.Then,byanalyzingtheundergroundtemperaturefielddataintheregion,thedepthanddistributionofpermafrostcanbeobtained.Finally,combinedwiththedesignandconstructionoftheChina-Russiaoilpipeline,reasonablemeasuresforpermafrostprotectionareproposed.ThesignificanceofthispaperistoprovidescientificbasisforthedesignandconstructionoftheChina-RussiaoilpipelinebydeeplystudyingthedistributioncharacteristicsofpermafrosttemperatureintheGreatKhinganMountainsarea,andcontributingtoenvironmentalprotectionandenergyconservation.Keywords:China-Russiaoilpipeline;GreatKhinganMountains;permafrost;distributioncharacteristicsofgroundtemperature;protectionmeasures.
