广东省城市流强度与结构的动态变化分析

Guangdong province urban flow strengthen and structure motivation change analysis

依据城市流强度分析方法,对2005年和2010年广东省21个地级市的区位熵、外向功能量、城市流强度、及其结构进行测算和分析。结果表明:①两个时段内广东省各城市的城市流强度逐步增强,但城市间及城市内部产业部门分配上差距较大;②城市间经济联系不够紧密,以广州、深圳为中心呈现核心-外围的空间结构;③各城市总体经济实力和城市综合服务能力之间尚不协调,多数城市总体经济实力较低;④2010年广东省的东翼、西翼和北部山区出现了主导型城市,小范围的区域经济发展的潜力巨大。据此提出了提高广东省城市流强度的对策,服务于广东省的经济发展。

Based on the model of the urban flows intensity and the congtact intencity among cities,by selecting 2005 and 2010 as two time sections, urban extrovert energy, urban flows intensity,urban flows tendency and urban flows structures about 21 cities in Guangdong province have been analysed.the results showed： ①intensity of urban flow in each cities is becoming stronger gradually,but the economic is imbalanced in cities and the difference is big on the distribution among departments of cities. ② The economic links between cities is not quit close and the contact among cities in Dongyi、Xiyi and the mount area is poor,Guangdong province has a Core-space structure with Guangzhou and Shenzhen as a center. ③Urben economy and comprehensive service of all cities are not coordinated, economy？strength？is？very？fragile in much more cities. ④ Up until 2010,the leading cities appear in Dongyi、Xiyi and the mount area and the economic potential of those regions is still large.
