Risk Assessment And Response Strategies For Extreme Climate Events In Key Nodes Of The Belt And Road, Yong Ge, Qiangzi Li, Feng Ling, Yuan Zhang, Yonghui Yao, Qingsheng Liu, Wen Dong, Hua Wu, Yi Li, Zhoupeng Ren
Bulletin of Chinese Academy of Sciences (Chinese Version)
In the context of global climate change, heat waves, extreme precipitation, extreme droughts and storm surges have increased in most areas of the Belt and Road, which seriously threatens the personal and property safety of countries along the Belt and Road. This study focuses on dealing with the issues associated with the risk identification and assessment of extreme climate events in the “Belt and Road” region, including the coarse or single assessment scale and weak response strategies. It develops a multi-scale extreme climate risk assessment framework, and completes the risk assessment of four representative extreme climate events including heat waves, …

Bulletin of Chinese Academy of Sciences (Chinese Version)
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-MongoliaRussia 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 …

Permafrost Engineering Problem Along China-Russia Crude Oil Pipeline And Mitigative Measure, Guoyu Li, Yapeng Cao, Wei Ma, Xiaoying Jin, Pengchao Chen, Qihao Yu, Zhongqiong Zhang, Yanhu Mu, Huijun Jin
Bulletin of Chinese Academy of Sciences (Chinese Version)
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 …
Spatial Pattern And Response Of Landslide And Debris Flow Risks In China-Pakistan Economic Corridor, Qiang Zou, Xiaojun Guo, Yu Luo, Yuanjun Jiang, Peng Cui, Lijun Su, Guoqiang Ou, Huali Pan, Weiming Liu
Spatial Pattern And Response Of Landslide And Debris Flow Risks In China-Pakistan Economic Corridor, Qiang Zou, Xiaojun Guo, Yu Luo, Yuanjun Jiang, Peng Cui, Lijun Su, Guoqiang Ou, Huali Pan, Weiming Liu
Bulletin of Chinese Academy of Sciences (Chinese Version)
Landslides and debris flows caused significant threat to the China-Pakistan Economic Corridor. This study introduced the spatial pattern of the relevant mountainous hazards and assessed the hazards risks, predicted the development trends, and proposed the relevant countermeasures as well. 584 landslides, 116 collapses, and 1669 mudslides in total were identified, which mainly distributed in the mountainous areas in the northern part of the corridor. The hazards were divided into five grades: extremely high, high, medium, low, and extremely low and the northern area is highly dangerous. The vulnerability assessment was carried out with traffic, economy, and population as indicators, and …

Bulletin of Chinese Academy of Sciences (Chinese Version)
This study analyzes the situation of China's foreign trade from January to November in 2020, and then three forecasting scenarios are constructed based on four aspects, including China's economic growth, the international demand, Sino-US trade friction, and the development of the COVID-19. Under these scenarios, a new decomposition and composition methodology is proposed to forecast 2021 China's foreign trade, by integrating the econometric models, artificial intelligence methods, and the system analysis method. In 2021, under the baseline scenario that the COVID-19 pandemic will be under certain control, the global economy exhibits slow recovery and China's economy grows steadily, the total …
New Characteristics And Trend Of Regional Innovation Capacity In China, Xielin Liu, Boxu Yang, Nan Xiao
New Characteristics And Trend Of Regional Innovation Capacity In China, Xielin Liu, Boxu Yang, Nan Xiao
Bulletin of Chinese Academy of Sciences (Chinese Version)
Regional innovation is an important carrier of innovation-driven development and plays an important role in regional economic growth. The evaluation of regional innovation capacity provides reference for central and local policy making. The China's Regional Innovation Capacity Evaluation Report of 2020 shows that innovation clusters with Beijing, Shanghai, Guangdong and Shaanxi as the centers have taken shape. Major progress has been achieved in building the global centers for scientific and technological innovation. Innovation capacity in the South is rising fast, while China's regional innovation capacity is still facing challenges. The gap between the East, the West and the South is …

Under the joint impact of the COVID-19 epidemic and the complex international situation, the future direction of China's economic development has attracted much attention. This study systematically analyzes and forecasts the development trend and regularity of China's medium and long-term economic growth rate. It is expected that the medium and long-term economic growth rate of China will show a downward trend in a wave shape. Based on the systematic integrated prediction approach on annual GDP growth proposed by our team, this study reviews China's economic development in 2020 and forecasts China's economic growth rate in 2021. It is expected that …
