Spatiotemporal pattern of climate change in the China-Myanmar Economic Corridor from 1901 to 2018

The China-Myanmar Economic Corridor(CMEC) is an important part of China's Belt and Road Initiative and an important area for global ecology and biodiversity. In this study, the annual and seasonal spatiotemporal patterns of temperature and precipitation in the CMEC over the past century were investigated using linear tendency estimation, the Mann-Kendall mutation test, the T-test, and wavelet analysis based on the monthly mean climatic data from 1901 to 2018 released by the Climatic Research Unit(CRU) of the University of East Anglia, UK. The results show that the CMEC demonstrated a trend of warming and drying over the past 100 years, and the rate of change in Myanmar was stronger than that in Yunnan Province of China. The warming rate was 0.039 ℃/10a. Precipitation decreased at a rate of -6.1 mm/10a. From the perspective of spatial distribution, temperature was high in the central and southern, low in the north of the CMEC, and the high-temperature centers were mainly distributed in the southern plain and river valley. Precipitation decreased from west to east and from south to north of the CMEC. From the perspective of the rate of change, warming was stronger in central and northern CMEC than in southern and northeastern CMEC. The rate of precipitation decline was stronger in the central and western regions than in the eastern region. This study provides a scientific reference for the CMEC to address climate change and ensure sustainable social and economic development and ecological security.

The Belt and Road Initiative and the Concept of an Economic Corridor along the Southern Silk Road

The Belt and Road Initiative requires the urgent revival of the Southern Silk Road. This means a good understanding of its rich historical connotations and its comprehensive and mutual-beneficial functions. Starting from a very early period, the Southern Silk Road has played an important role in the history of Yunnan and has been characterized by using cowry as money. This paper proposes the development of a new economic corridor along the Southern Silk Road from Xi'an in the north, via Chengdu and Kunming, to South Asia and Southeast Asia thus linking the Silk Road Economic Belt to the 21 st Century Maritime Silk Road. This will bring about a new phase of all-around opening-up linking domestic and overseas markets via land and sea.

中国—东盟经贸合作:西部陆海新通道的现状考察

西部陆海新通道承担着中国西部内陆腹地通达东盟、连接世界的桥梁和枢纽的重任。基于2017-2021年省际—国别(地区)的细分产品贸易数据,从“设施联通及贸易畅通”“产业优势互补和贸易升级”“产业链供应链布局”三个方面考察了西部陆海新通道沿线省份与东盟国家的经贸合作情况。研究发现,通道沿线交通基础设施建设迅速推进,物流功能不断完善。东盟国家对沿线省市出口结构升级明显,沿线省市面临高、低技术生产环节双重压力。东盟国家与沿线省市产业优势互补性较强,但集成电路产业上游的进口来源地较为集中,一定程度上面临被“卡脖子”风险。应在“以通道促贸易”基础上进一步实现“以贸易聚产业”,加快促进产业和贸易结构优化升级,围绕通道积极谋划产业链供应链布局。

“俾路支解放军”恐袭新动向及中国参与治理的策略

巴基斯坦长期受到恐怖主义危害,猖獗的恐怖活动既迟滞了国家的正常发展,又严重掣肘了国际共赢合作。随着中巴两国经济的深度合作,尤其是中巴经济走廊建设“红利”的不断释放,两国利益更加交融,交流更加广泛,民众更加受益。但是,中巴经济合作亦面临着越来越多的恐袭危害,“俾路支解放军”日益成为头号威胁。近年来,“俾路支解放军”针对在巴中国项目、机构和人员的恐袭频次增多、对象扩大、手段更无人性,出现了一些新动向。这既与俾路支民族本身所固有的历史和文化因素有关,又与俾路支地区长期存在的结构性矛盾和域外大国的挑拨离间脱不了干系。为了应对“俾解”对中国在巴利益的严重威胁,中国应努力消除“俾解”恐袭动员的经济社会根源,推动中巴共赢合作长效机制的建设。

Evaluation and prediction of engineering construction suitability in the Chinae-Mongoliae-Russia economic corridor

It is proposed to build a high-speed railway through the China‒Mongolia‒Russia economic corridor(CMREC)which runs from Beijing to Moscow via Mongolia.However,the frozen ground in this corridor has great impacts on the infrastructure stability,especially under the background of climate warming and permafrost degradation.Based on the Bayesian Network Model(BNM),this study evaluates the suitability for engineering construction in the CMREC,by using 21 factors in five aspects of terrain,climate,ecology,soil,and frozen-ground thermal stability.The results showed that the corridor of Mongolia's Gobi and Inner Mongolia in China is suitable for engineering construction,and the corridor in Amur,Russia near the northern part of Northeast China is also suitable due to cold and stable permafrost overlaying by a thin active layer.However,the corridor near Petropavlovsk in Kazakhstan and Omsk in Russia is not suitable for engineering construction because of low freezing index and ecological vulnerability.Furthermore,the sensitivity analysis of influence factors indicates that the thermal stability of frozen ground has the greatest impact on the suitability of engineering construction.These conclusions can provide a reference basis for the future engineering planning,construction and risk assessment.
