The local factors such as topography, vegetations and soil moisture contents, have great influences on the distribution, ground temperatures, and ground ice contents of permafrost. About 50 km of wetlands have been identified along the China-Russia crude oil pipeline route. In these segments, the surficial deposits consist of peat and humic layers on the top of thick ground-ice, or ice-rich permafrost. The frozen ground engineering geology conditions in wetlands generally are the worst for building and operating the pipeline. The hazardous periglacial processes, such as the widespreadpresence of pingos, icings and frost mounds due to the extensive occurrence of the frost-susceptible soils and ample supplies of surface and ground waters in winter pose significant threats on pipeline operation.

地形地貌单元、植被分布、地表水分条件的变化等局部因素对多年冻土的分布和地下冰的赋存产生重要的影响，管道沿线大约分布有50 km左右的沼泽湿地，其表层为腐殖质土及泥炭层，泥炭层下面分布着含土冰层或地下冰，是管道沿线最差的冻土工程地质地段；由于中俄原油管道沿线水系发育多，冻胀丘、冰椎和冰幔等不良冻土现象广泛分布。
