安徽沿淮经济带城镇体系空间布局研究

安徽沿淮经济带现代城镇体系初具雏形，但城镇化绝对水平仍然较低且内部发展不平衡，城市区域带动能力偏弱，城镇基础设施建设相对落后，区域人口外流逐渐增多。在准确预测经济带2013—2030年人口规模和城镇化水平前提下，综合运用PCA方法和引力模型确定经济带区域中心城市并测度其辐射强度，提出应充分考虑沿淮经济带安徽段实际经济社会发展水平和生态资源环境条件，依托沿淮经济带现有的城镇空间布局重点和产业发展基础，坚持城镇发展与资源、环境相协调，实施核心城市引领、中心城市带动战略，最终形成安徽沿淮经济带“一轴、双组团、多节点”的开放型、网络状城镇空间结构。

On Urban System Spatial Layout of the Economic Belt Along the Huai River in Anhui Province

Modern urban system of the economic belt along the Huai River in Anhui Province has been formed, but its urbanization level is still low and uneven, its driving ability is weak, its urban infrastructure construction is relatively backward, and the regional population outflow gradually increases. According to the accurate prediction of its population scale and level of urbanization from 2013 to 2030, with integrated use of PCA method and gravity model to determine its economic center cities and measure their radiation intensity, the paper proposes that the actual level of economic and social development and ecological resources and environment conditions should be fully considered in this economic belt, the existing towns and foundation of industrial development should be relied on, the coordinated urban development and resources and environment should be adhered to, and the strategy of core city and center city should be implemented, so that the open type of ＂one axis, two groups, multi nodes＂, and the network of urban spatial structure in the economic belt along the Huai River in Anhui Province can finally be formed.
