Abstract ( 172 )
The study of geographical environment characteristics and evolution rules is an important scientific support for recognizing the international geopolitical situation and safeguarding national security. Since 21 century, the rise of frequency and influence of all kinds of geopolitical events causes a serious threat to China's geopolitical safety and implementation of "the Belt and Road Initiative". The occurrence of geopolitical events is the result of interaction of various geo-environmental factors. The analysis of the evolution process of multi-dimensional geopolitical elements is an important basis for simulation and early warning of geo-risk. This paper reviews the origin and historical progress of the research on geo-environment both at home and abroad, systematically combs the main observation means of geo-environmental factors, and sums up application results of big data technology in the field of geo-environment research. Research shows that single geopolitical events have a high degree randomness, but the occurrence of massive events is affected by various geo-environment factors. Based on geo-environment system theory, the paper describes the complex relationship between geographical environment factors by using a large data analysis method, which helps to solve the problem of specific geographical. Finally, the paper suggests that the future geo-environment research should be guided by the geo-environment system theory and uses big data mining and machine learning technology to construct a spatiotemporal simulation and intelligent analysis model of geo-environment.

Abstract ( 136 )
In this research, the energy efficiencies of China, Mongolia and Russia are analyzed for the period of 2000 to 2014. The conditions of energy utilization and carbon dioxide emission are investigated through the data from IEA and World Bank. The total factor energy efficiency is calculated with super SBM and window DEA model. Besides, regression analysis is used to identify the influencing factors. The result indicates that Chinese energy consumption and carbon dioxide emissions were higher than Russia and Mongolia. Chinese and Mongolia energy consumptions and carbon dioxide emissions were closely related. The energy efficiency in Russia from 2004 to 2009 was the highest while Chinese was the highest from 2009 to 2014. Moreover, the economic development and energy trade increment had positive effects on energy efficiency, whereas both input of high energy consumption and proportion of industrial would bring negative influences on energy efficiency.

Abstract ( 129 )
There are a wide range of energy minerals and abundant reserves in the sub-Saharan Africa region. The natural mineral resources endowments are highly attractive to investment. Thus, it is important to strengthen the construction of energy and mineral investment in sub-Saharan region for promoting the implementation of "the Belt and Road Initiative" (B&R). This paper uses the fishbone diagram to analyze the primary and secondary factors of energy and mineral investment, which takes into account the energy and mineral reserves, socioeconomic factors, natural geography and political diplomacy in sub-Saharan Africa, and pays much attention to the energy and mineral investment factor. It provides an analysis model of energy and mineral investment in sub-Saharan Africa based on the multilevel fuzzy comprehensive evaluation method. Based on the selection of index, establishment of index system and analysis of index weight, it also presents a study and evaluation analysis of the main investment factors, and obtains the investment weight ranking of energy and mineral industry among sub-Saharan African countries. Rich energy reserves and good geographical suitability are the greatest investment attraction; the capacity of diplomacy, legal environment and culture are the main risk factors that investment may face; the comprehensive investment environment is "excellent". This study provides a scientific basis and objective understanding for Chinese enterprises in the field of energy and mineral resources to invest in sub-Saharan Africa.
