SPACE-TIME SYNERGISTIC DEVELOPMENT AND EVOLUTION PATTERN BETWEEN SUPPLY AND DEMAND SYSTEMS OF URBAN-RURAL ROAD NETWORK IN WUHAN METROPOLITAN AREA

In recent years, the regional integration process has been accelerated, the construction of new countryside and villages and towns space renovation was intensified, the fast development of urban and rural road network is resulted in road network space constantly refactoring and transformation. With sharp dynamic transition and spiral succession, the urban and rural road network system in the composition, structure, function, system evolution and interaction mechanism is complicated. This article deconstructs the urban and rural road network system for two sub-systems(supply system and demand system), and builds the evaluation index systems for each one, to discuss the space-time development of the supply-demand system of urban-rural road network of Wuhan Metropolitan Area from different spatial scales for the purpose of providing theoretical guidance and decision-making basis for our country in urban-rural road network optimization. On the city level, the supply system presents a space growth trend of core-periphery, the demand system shows a spatial pattern of Wuhan city dominated. On the county level, the spatial difference of supply system is small, and the supply system presents a layers' space development pattern.
