Research On The Development Of My Country's Air Cargo Flow Network And Its Regional System

In recent years,air cargo has become a research hotspot,and the attention of various countries to civil aviation has been on the rise.As the most important infrastructure of civil aviation,transport airport is also an important part of national comprehensive transportation infrastructure.In order to fully implement “the national civil airport layout plan”,the general administration of civil aviation of China(CAAC)has made it clear in the relevant contents of the "enhanced transport airport guarantee capability" in the 12 th five-year plan: during the 12 th five-year plan period,we will energetically develop the five major hubs in the north,east China,central south,southwest and northwest.Implementing the hub strategy to meet the needs of integrated transportation integration to strengthen the functions of the pearl river delta,Yangtze river delta,Beijing-Tianjin-Hebei region and other regional airports,and promote the formation of multi-airport system.In the 13 th five-year plan,100 major projects built more to speed up the large aircraft development,Beijing's new airport,more than 50 new civil transport airport,vigorously promoting Shanghai,Tianjin,Dalian,Xiamen international shipping center construction,etc.China's air transport capacity is growing rapidly,with airlines and airports covering an increasingly wide range of areas and cities,and flight schedules are available throughout the day.In regional the contact interaction and spatial relationship of social economy,the higher time efficiency and the economic efficiency and make the air transport become an important mode of transport organization,important influence on the regional economic development.Based on this background,the integrated use of polarization theory,the agglomeration effect theory,and the theory of distance decay,from air cargo space change process in our country,from various angles analysis using ArcGIS software development and regional aviation goods traffic network system in our country,hope to promote the development of Chinese air freight and optimize the route network layout.The thesis is divided into four parts.The first part is the introduction to the first chapter,which mainly explains the basis of the thesis,relevant research trends,research methods and data sources,etc.The second part is the second chapter,which is mainly related to the theoretical basis,and the basic meaning of each theory is introduced in detail,which provides theoretical support for the research of this paper.The third part includes the third chapter,the fourth chapter and the fifth chapter,mainly through quantitative and qualitative analysis method,with China southernairlines,Air China and China Eastern airlines as the research object,based on flight schedule data,airlines,airport to make nuclear density analysis diagram,analyze the spatial pattern of the aviation network;based on the standard deviation ellipse and spatial gini coefficient,using data from 2000~ 2016 airports and segment analysis of China's air cargo space variation characteristics,so as to the air cargo industry development strategy and air cargo layout optimization provide decision-making reference.Furthermore,the interaction characteristics of Chinese cities are discussed,and the development of China's air cargo network and its regional system are discussed.The fourth part is chapter 6,which is the conclusion part of the paper,and discusses the shortcoming of the article and the future research.Through research,this paper draws the following conclusions:(1)The regional spatial distribution of air cargo in China is extremely unbalanced.The air transport status in the eastern region is extremely prominent,and the western region is relatively strong,while the central and northeast regions are relatively weak.Air flow distribution in eastern and western,central region between the northeast of China,and eastern and western regions of its internal communication is given priority to,western,central and northeast minimal air flow between the three regions;(2)Aviation goods traffic network system in China has formed a distinct regional differentiation phenomenon,plays a significant role in aviation goods traffic distance attenuation law of megacities is aviation goods traffic is concentrated,as the hub of the organization of the network has great social and economic significance;(3)China's air cargo network has a remarkable "spot-spoke" system.Three cities as Beijing,Shanghai,Guangzhou national air cargo center,radiation as the core of the Yangtze river delta region in Shanghai,Hangzhou,Guangzhou,Shenzhen as the core of the pearl river delta area,Beijing Tianjin as the core of the Beijing-Tianjin area and developed area of Chengdu and Chongqing in the west and air cargo network by hybrid network to shaft radial hub network transformation,formed from a single airport hub development of Beijing and Tianjin,the Shanghai and Hanzhou,Guangzhou and Chongqing four combination hub,air cargo center from the southeast coastal areas to inland northwest direction.
