Abstract： The Belt and Road region crosses different geographic areas and ecological zones. Ecologic problems and hazards risks are complicated in these zones and they threat seriously the green development and economic corridors security along the Belt and Road region. Based on multiple data sources platform installation and experiment-demonstration researches and observations, the regional ecologic-environmental regulations of the Belt and Road region are well and scientifically recognized, key areas/zones and the ecologic-environmental security and risk response programmes of major projects are systematically integrated. The findings of the key advanced research project on the environment change and construction of the Green Silk Road of the Pan-Third Pole provide scientific and technical supports to the further promotion of the Green Belt and Road development, and they also serve the world successful cases for global environmental governance.

Abstract： Desertification, since initial recognition in 1927 and common definition in 1992, through its vicissitudes, is still one of the serious global environmental issues face the world and exists as the bottleneck of the development. Desertification threats the terrestrial ecological security and limits the sustainability of socio-economic development. In consideration of the impacts of desertification, an “Earth Cancer” and a persistent disease, the authors contribute four prescriptions of “good medicines” for the global initiatives to combat desertification, on the basic framework of Chinese strategies and experiences of “four horizontal beams and eight pillars”, in line with the 15.3 goal of Sustainable Development Goals (SDGs); namely, development of Protocol of United Nations Convention to Combat Desertification (UNCCD) and unification of Weights and Measures” (benchmarks and indicators) of the implementation and compliance of the UNCCD; setting up of global observation network to monitor the area change of dryland change; compilation of global natural desert (heritage) directory to leave behind landscape of aboriginal sand sea for future generations; initiation of “global governance action to combat desertification” to strive for achieving the target of Land Degradation Neutrality (LDN) at 2030.

Abstract：基于图形学分析技术，采用追踪算法、矢量分析法，利用常规MICAPS数据、NECP逐日再分析资料和EC细网格资料,对我国西北地区致旱天气系统进行识别试验。通过试验，得到如下结论：① 依据天气学定义，利用追踪算法能够成功识别高空槽、高空脊等主要系统,并可得到其曲率特征；② 利用该方法识别天气尺度系统，系统中心识别率高达90%以上、平均误差小于0.5°，而高空槽识别准确率为74%~87%，平均识别误差为0.7°~1.4°。利用风场进行订正后，准确度明显提高、误差有所减小，基本可以满足干旱预测、预报业务需求。
