武汉城市圈空间组织演化评价

空间组织演化是空间自组织演化和经济社会发展耦合协同作用的结果。以武汉城市圈为研究对象，比较研究长三角、珠三角城市群和京津冀都市圈，利用空间相互作用强度、区域交通通达性和道路网络性评价武汉城市圈空间组织。结果显示：武汉城市圈在总量和规模等级等指标表征上弱于比较对象一个层级，尚处于发育的初级阶段；但武汉城市圈结构性指标表征良好，城镇空间组织演进良性，空间结构表现合理，从道路的网络性和通达性方面，与发达城市群（都市圈）差异不大，某些指标甚至超过了比较对象，表明武汉城市圈虽处于发展的初级阶段，但总体结构以及组织演化科学合理，发展健康

EVALUATION OF THE SPATIAL EVOLUTION OF THE ORGANIZATION OF WUHAN METROPOLITAN AREA

Metropolitan area is urban system with high integration trend and close spatial relationship. Metropolitan growth is the coordinate evolution results of the spatial self organization evolution and regional economic and social factors, its also embodies the law of spatial mapping in human society. Metropolitan spatial evolution by three major mechanisms: self organization evolution, economic and social development level and regional and the former two coupled together. The existing research focused on the following aspects: the spatial self organization evolution, spatial structure reasonable, spatial form. At the same time, some researchers focus on how to establish index system for evaluation coordination degree of ecological environment, spatial cooperation crossing regional and its methods. spatial evolution is a synergistic evolution effect with spatial self organization and economic social development. It is difficult to metric spatial organization level, therefore, the evolution of metropolitan spatial organization and spatial structure evolution are realized by spatial interaction. Spatial interaction can reflect the function of central city field, overall scale of regional economic and social development, spatial organization strength and government role in them. Spatial interaction is realized through traffic network, traffic network construction needs for government guidance and meet the objective demand of spatial organization in China. So we select intensity space connection and reasonable degree of traffic construction to represent metropolitan spatial organization. The authors take Wuhan Metropolitan area as the object of research, doing research into its spatial organizational structure by comparing it with Yangtze River Delta Metropolitan area, Pearl River Delta Metropolitan area and Beijing Tianjin Hebei Metropolitan area, using spatial interaction intensity, regional traffic accessibility and road network as indexes. It shows that Wuhan Metropolitan area is still in the primary stage of its development, and is at a lower level in terms of its total amount and scale. However, the structural indicators of Wuhan Metropolitan area fare well, its spatial organizational structure develops well and its space is well structured. There is little difference with developed urban clusters (metropolitan area) in terms of road networks and traffic accessibility. Some of the indexes even outshine others. This shows that although Wuhan Metropolitan area is in the primary stage of its development, its overall structure and organizational structure evolves in a scientific and sound way
