The article reports the results from the analysis of content and distribution of petroleum hydrocarbons in the soils of geochemical landscapes in southern Sakhalin. It discusses the main types of soil formed in this region and the parameters determining the migration of petroleum hydrocarbons in the landscapes. It has been shown that the soils of transit-accumulative and accumulative landscapes are characterized by the highest content and the penetration depth of petroleum hydrocarbons into the soil profile. In the event of accidental oil spills, along with lateral migration, a significant role is played by vertical migration of petroleum hydrocarbons to the accumulative landscapes.

萨哈林岛南部地球化学景观土壤中石油烃的含量和分布

本文报道了萨哈林南部南部地球化学景观土壤中石油碳氢化合物含量和分布的分析结果。它讨论了该地区形成的土壤的主要类型以及确定景观中石油碳氢化合物迁移的参数。研究表明，过境积累型和累积型景观土壤的特征是石油烃含量最高，渗透深度最大。在意外漏油的情况下，随着横向迁移，石油碳氢化合物垂直迁移到累积景观中将发挥重要作用。
