    Subjects: Other Disciplines >> Synthetic discipline submitted time 2023-03-28 Cooperative journals: 《中国科学院院刊》

    Abstract: The China-Russia Crude Oil Pipeline (CRCOP), one of the four key national energy strategic channels, plays an important role in ensuring national energy security, diversifying oil supplies and transportation patterns, promoting the China-Mongolia-Russian economic corridor, and deepening Sino-Russian strategic cooperation. Aiming at permafrost engineering problems along the CRCOP, the principles of thaw control are put forward. This study develops a set of innovative techniques for mitigating and controlling the thaw of permafrost foundation soils of the pipeline, which provides an important guarantee for the green construction and safe operation of the CRCOP and can protect the permafrost environment along the pipeline route. The research results can offer important references and basis for design, construction, and maintenance of the similar projects in permafrost regions.

  • Regionalization of Ecological Risk of China-Mongolia-Russia Economic Corridor Transportation and Pipeline Construction and Policy Suggestions

    Subjects: Other Disciplines >> Synthetic discipline submitted time 2023-03-28 Cooperative journals: 《中国科学院院刊》

    Abstract: The cross-border railways and oil and gas pipelines along the China-Mongolia-Russia Economic Corridor are key hubs and channels supporting the regional cooperation and development. It is very important to complete scientific regionalization of ecological risk of China-Mongolia-Russia Economic Corridor and put forward suggestions to guarantee smooth construction and safe cross-border traffic project. By establishing ecological risk evaluation model, we quantitatively analyzed the ecological risk of China Mongolia#2;Russia Economic Corridor, and regionalized high, middle, and low risk. We put forward the ecological risk prevention and control countermeasures for China-Mongolia-Russia Economic Corridor. It shows that the ecological risk areas are distributed along the “two belts and one line”. The risk of desertification is along the China-Mongolia-Russia cross-border traffic belt, the risk of permafrost is along the China-Russia cross-border traffic belt and the China-Russian crude oil pipeline. The proposed suggestions are designated to prevent and control ecological risk from the perspectives of promoting ecological civilization to realize a “two-highs and three-lows” mode; constructing of a green economic corridor, optimizing the industrial structure, actively establishing a four-tier circular economy system, and developing green circular industries; innovating technical biological engineering; establishing system and mechanism of an international cooperation and monitoring ecological risk network system along China-Mongolia-Russia Economic Corridor. We provide scientific technic support for rationally building cross-border railways and pipelines, avoiding and preventing ecological risks in China#2;Mongolia-Russia Economic Corridor. It will be decision-making basis to promote regional green and sustainable development.
