中國區(qū)域3E系統(tǒng)發(fā)展水平的空間差異演化研究
[Abstract]:In the face of tight resource constraints, serious environmental pollution and ecosystem degradation, severe situation. The interaction and coordinated promotion of energy, economy and environment are the realistic preparation and guarantee for China to take the path of sustainable development. Therefore, based on China's basic national conditions, we must organically combine economic growth with energy green development and environmental construction, and promote the overall effect of the whole country through the coordination of the three systems. Based on the idea of coordinated development of 3e system, this paper establishes a comprehensive evaluation system of comprehensive development level of 3e system by using the evaluation method of index system, and uses the principal component analysis method to analyze the energy resources from 1996 to 2010. The comprehensive development of economic and environmental subsystems and 3e system is evaluated. At the same time, exploratory data analysis and Markov chain method are used to explore the spatial distribution characteristics and evolution rules of regional 3E system in China. Finally, the paper discusses the influence of spatial difference on the development and change of regional 3e system, and puts forward some relevant policy suggestions according to the spatial distribution of regional 3e system in China. The conclusions of this paper are as follows: (1) in the last 15 years, the development level of energy, economy and environment system in China has been gradually improved, but the regional distribution is obviously different. The development level of 3e system in the south coast, east coast and southwest area is higher, but the development level in the north coast and the northeast area is lower. The difference between the above two groups is great, but there is no significant difference between the two groups. The high level of economic development in coastal areas, to a certain extent, ignored the coordinated development of the environment. According to the development of each subsystem, the development level of China's energy system fluctuates around the average value and tends to be stable. At the same time, the overall development level of China's economic system and environmental system shows an upward trend. (2) the change of the comprehensive development level of the 3e system in the region of China has a certain degree of convergence in 1996-2010. Low-level regional convergence is more significant, while low-and middle-and high-level regional convergence is common, and at the same time, The two regional types are being upgraded and developed. (3) the long-term development trend of the 3e system in China is influenced to some extent by the neighborhood type. In the long run, when the observed area neighborhood type is medium-high level, the long-term development trend of the 3e system in China is affected by the neighborhood type to a certain extent. The development potential of regional upgrading is the greatest. (4) the eastern coastal area has a slight decline in recent years affected by the large decline in the northern region; The convergence of the southern coastal area and the eastern part of the Yellow River is obvious, and the development of the northern coastal and northeast regions has encountered bottlenecks, and as a low-level region, the convergence phenomenon is remarkable, which is less affected by the neighborhood: the middle reaches of the Yellow River has a great potential to upgrade to a high-level region; Under the positive influence of the middle reaches of the Yellow River and the southwest of the Yangtze River, the middle reaches of the Yangtze River is upgrading and developing, and the positive effects of the middle reaches of the Yellow River and the south of the southwest of the Yangtze River are expected to upgrade to a higher level, respectively.
