摘　　要：运用城市流强度定量分析方法,对中国十大城市群99座城市的外向型功能量、城市流强度和城市流倾向度进行计算,并汇总求出各城市群的上述指标,进而对城市群间城市流强度、各城市群核心城市及各城市群内部城市的城市流强度相关指标进行分析,分析结果显示:城市群间外向型功能量和城市流强度存在巨大差距,并存在从东南沿海到西部地区逐渐减小的态势,京津唐、长三角、珠三角为三大高城市流强度的辐射中心;东部地区城市群从业人员中为城市区域以外的地区服务的人员比例普遍较低,其中长三角最低仅为11%;核心城市的外向型功能量和城市流强度变化趋势与城市群一致,对城市群影响巨大,北京、深圳和上海三座城市综合实力和外向型服务能力最强,北京服务型产业在全国也有着超强的辐射功能;城市群内城市的城市流强度差巨大,核心城市的总体实力、城市流强度均较高,但无一例外的其GDPi′值大于其Ki′,表明进一步提升其综合服务能力十分必要,非核心城市则更应着眼于综合实力的提升。Uses the quantitative analytical methods, calculates the extrovert energy, the intensity of urban flow and the degree of tendency of 99 cities of top ten urban agglomerations, and calculates separately the total number of the relevant index, analyses the relevant index among urban agglomerations, core cities and internal city of every urban agglomerations, the results show： the extrovert energy and the intensity of urban flow exist a huge gap among urban agglomerations, gradually decrease from east to west, Pearl River Delta, Yangtze River Delta and Beijing- Tianjin- Tangshan are stronger than others; Group of employees in the eastern part of the city for urban areas outside the region the proportion of Service personnel is generally low, only one of the lowest 11% of the Yangtze River Delta; the changes in trends of the intensity of urban flow of core cities consistent with urban agglomerations, it shows that the core of the city played a major role, the most powerful cities in overall strength and service - oriented capacity are Beijing, Shanghai and Shenzhen, the service - based industries.of Beijing have particularly strong feature of the radiation; the intensity of urban flow exist a huge gap among internal city of every urban agglomerations, the overall strength and urban flow intensity of the core cities are high, However, without exception, greater than its value, the service- oriented capacity of core cities need to be further strengthened, non - core cities is even more necessary to focus on enhancement of comprehensive strength.
