基于城市流强度理论模型,对泛珠江三角洲经济圈117个地级市2003年和2012年的城市流强度和结构特征进行测算,并依此对经济圈的空间联系进行分析。结果表明,经济圈城市流强度值偏小的城市数量多于75个,城市间的空间联系偏弱,城市流强度存在明显的区域差异。主要原因是区域发展不均衡,综合经济实力较弱的城市数量超过65个,产业的外向服务能力不足。第二产业对经济圈城市流强度影响大于第三产业,第三产业对城市流强度的影响逐渐增强。随时间发展,经济圈城市流强度由受第二产业主导变为二、三产业共同影响。泛珠江三角洲经济圈仍处于工业化发展阶段,未来城市空间联系的格局和演化还可基于城市职能及发展要素的空间分布关系等方面进行调控。
基于城市流彊度理論模型,對汎珠江三角洲經濟圈117箇地級市2003年和2012年的城市流彊度和結構特徵進行測算,併依此對經濟圈的空間聯繫進行分析。結果錶明,經濟圈城市流彊度值偏小的城市數量多于75箇,城市間的空間聯繫偏弱,城市流彊度存在明顯的區域差異。主要原因是區域髮展不均衡,綜閤經濟實力較弱的城市數量超過65箇,產業的外嚮服務能力不足。第二產業對經濟圈城市流彊度影響大于第三產業,第三產業對城市流彊度的影響逐漸增彊。隨時間髮展,經濟圈城市流彊度由受第二產業主導變為二、三產業共同影響。汎珠江三角洲經濟圈仍處于工業化髮展階段,未來城市空間聯繫的格跼和縯化還可基于城市職能及髮展要素的空間分佈關繫等方麵進行調控。

Based on the theory model of urban flow, the intensity and structure of urban flow in 117 cities of Pan-Pearl River Delta Economic Zone in both 2003 and 2012 are calculated and analyzed, and thereby the space relation of economic circle is analyzed as well.The results showed that more than 75 cities have a smaller intensity of urban flow and a smaller space relation and there exists significant regional differences in the intensity of the ur-ban flow owe to uneven regional development.More than 65 cities have a smaller economy power and a smaller out-ward service function.The intensity of urban flow still obtains a lager benefit from the secondary industry than from the tertiary industry, the impact of the tertiary industry in urban traffic intensity gradually increased.With time go-ing on, the intensity of urban flow has been affected by both the secondary and tertiary industries from dominated by the secondary industry.The Pan-Pearl River Delta Economic Zone is still in the development stage of industrializa-tion, future structure and evolution of urban spatial linkages could be regulated based on both urban function and spatial distribution of development elements.
