摘要
基于人口、经济地理集中度、区位熵、城市流强度和经济隶属度等指标,综合分析了2000-2017年珠三角城市群人口、经济、产业集聚水平和空间关系的时空演变过程;提取了5期城区边界,并分析了城区扩展速率、强度和方向;基于空间引力模型测算了各市城镇化空间引力潜力。结果表明:①珠三角城市群城镇化空间网络联系水平不高,东西两岸发展不均衡,"核心-外围"特征明显,经济发达地区人口集聚滞后;②城际经济联系较松散,城市流强度差异悬殊,广州辐射带动作用明显,以工业外向服务功能为主的深圳,在珠三角范围内的工业区位熵失去优势,综合对外服务功能优势不明显;③城镇化集聚特征与经济联系密切相关,在空间上呈现一致性,城镇化空间集聚最明显和经济联系最密切的区域高度拟合;④陆地地理邻近集聚特征明显,沿海岸线经济联系不足,珠海与广州、深圳的海上经济联系有待加强。
Based on the images and statistics of the Pearl River Delta from 2000 to 2017, we used the geographical concentration, location quotient, urban flow intensity, economic membership grade and urban expansion to analyze the agglomeration levels of population, economy, industrial, and the spatio-temporal evolution process of spatial relationship in Pearl River Delta urban agglomeration from 2000 to 2017. The conclusions show that(1) the urban agglomeration spatial network connection in the study area is not high, it still has a clear "Core-Periphery" characteristic, and people agglomeration lags behind in the economic developed areas.(2) The inter-city economic relations are very loose in this region, there are huge differences in the intensity of urban flow between cities. Guangzhou plays a leading role and it has a strong correlation effect. However, Shenzhen, which mainly depends on industrial outward service, has lost its advantage in the region, its comprehensive function yet need to be enhanced.(3) The characteristics of urbanization are closely related to economic agglomeration, and they have high consistency in space.(4) The geographical agglomeration characteristics of the lands are obvious, but the economic links are not enough. The links between Zhuhai, Guangzhou and Shenzhen should get more focused.
