Spatial Structure Of Central Poyang Lake Urban Group And Economic Ties

Poyang Lake Ecological Economic Zone is a new strategic fulcrum of economic and social development in Jiangxi Province. For this new town group, studying its spatial structure of internal and external economic link is conducive to the understanding urbans’ economic link hierarchy structure of the economic zone; investiging the intensity of urban flow is helpful to grasp its industry structure. From two aspects of space and function cantact to comprehensively analyze the economic links, it will not only be a supplement of urban agglomeration theory of economic link but also provide a degree of guidance on the economic and social development of north of Jiangxi from a new and more specific view. In this paper, calculate and analyze the economic link and flow strength between towns and cities in the Poyang Lake urban group, research the economic link and its evolution of the Poyang Lake town group from point, line, surface, time four dimension, and lastly draw the following results:1、Poyang Lake urban group is in the initial period of regional development, each city has a relatively balanced development to become the polarization center within its scope, and then make the whole Poyang Lake town group get a balanced structure of its economic link.2、Poyang Lake town group the three industrial structure of Poyang Lake town group is11.0:57.3:31.7in2010, which is a "two-three-one" industrial structure, each town is still dominated by traditional agriculture, and has a small proportion of the tertiary industry, especially the new emerging service industry, electricity、gas、water production and supplement, public administration and social organizations, education and other industries are its dominant industrys.3、Poyang Lake town group economic link in the region direction shows an obvious character of traffic and central cities direction, and mainly to the central China’s Wuhan and Changsha, the Pearl River Delta Shanghai-Nanjing-Hangzhou Area, southern China’s Guangzhou. According to the internal and external economic link strength、direction and current situation of Poyang Lake town group, select four economic development axes into two levels to guide the development of Poyang Lake town group:Beijing-Kowloon line, Zhejiang-Ganzhou line, Fu-Yin high-speed roads as the first level axis and Yingtan-Shangrao, Nanchang-Fuzhou, Nanchang-Yichun three laps around the lake as the second axis, which constitute economic link network for the development of Poyang Lake town group area.4、it will contribute to grasp spatial structure and characteristics of urban system and determine the stage of development to study economic link strength of town group, Poyang Lake town group is now entering a period that its internal economic link is deepening, spatial structure shows circle structure and multi-center trend is rapidly developping.
