摘　　要：中俄输油管道工程对实现我国原油供应多元化,提高石油安全具有重要的战略意义。兴安岭地区湿地和冻土具有共生特性,输油管道工程对沿线湿地将形成一定的影响,主要表现在施工期对植被根系、盖度和泥炭层形成一定的破坏,以及运营期冻胀和融沉对湿地形成的影响。上述影响又将作用于下伏冻土的水热过程,进而威胁输油管道的稳定性和运营安全。通过特定的植被移植和增添泥炭层等方法,将能够有效地抵消不利影响。The China-Russia Crude Oil Pipeline from Mo＇he to Daqing is strategically important for improving the energy safety of China through the diversification of petroleum supplies. The permafrost and marshes in Hinggan Mountains have a symbiotic relationship. However, the pipeline construction and operation will have some adverse impacts on the wetlands along the pipeline route through the damage to plant roots, vegetative coverage and peatlands, and through the disruptions of wetland surface resulted from the frost heaving and thaw settlement during the pipeline operation period. In turn, these processes will affect the heat-moisture processes of the underlying permafrost, posing a threat on the stability of the pipeline foundations and operational safety. These hazards can be mitigated by certain methods, such as the revegetation of the construction sites and addition of a peat layer between the foundation soils and the pipeline.
