【摘要】：研究京津冀地区空间结构的特征和演化过程,意在为京津冀地区的空间布局规划提供一定借鉴；尝试利用可达性技术修正研究空间结构的经典模型,更新空间结构研究的理论因子。此为本文的研究目的。 以京津冀地区154个城镇为基础研究单元,在测算可达性的基础上,分析区域空间关联和空间联系特征,以揭示京津冀地区空间结构自1995年来的演化过程。基于以上分析结论与京津冀地区现有规划方案的对比,提出对京津冀地区空间结构规划的建议。 采用成本加权栅格算法测算京津冀地区的可达性,纵向分析1995年、2003年和2011年京津冀地区可达性空间格局的演化。在区域视角下,可达性整体显著提高,但改善程度存在内部差异。在两两城镇间,可达性水平提高,可达性结构得到改善,一日交流圈内的城镇数量增多。分别基于可达性空间权重矩阵、边邻接权重矩阵和反距离权重矩阵,对京津冀地区进行热点分析,对比发现可达性空间权重矩阵能更好地拟合现实。选择基于可达性空间权重矩阵测算LocalMoran's I系数,分析京津冀地区高原区、山地区、平原区和盆地区等四个经济发展类型区的空间分布演化特征。引入可达性修正引力模型和场强模型,研究京津冀地区空间联系。京津冀地区城镇间经济联系的特征反映在经济流量和流向两方面。在流量上,呈现由均衡局势演化为急剧聚集局势,而北京和天津是稳定的核心经济流量集聚地,石家庄和唐山是次级汇。在流向上,组团发展明显,一轴两带结构渐趋明朗,即京津发展轴和环渤海带、唐山——北京——石家庄——邯郸一带。京津冀地区空间关联和空间联系的有关结论与吴良镛“一轴三带”和肖金成“一轴两带三城四区”的规划方案相契合,并提出对该地区空间结构规划的建议,表明基于可达性分析京津冀地区空间结构具有现实指导意义。
[Abstract]:To study the characteristics and evolution process of spatial structure in Beijing-Tianjin-Hebei region is to provide some reference for the spatial layout planning of Beijing-Tianjin-Hebei region. This paper attempts to modify the classical model of spatial structure by using reachability technique and to update the theoretical factors of spatial structure research. This is the purpose of this paper. Taking 154 towns in Beijing-Tianjin-Hebei region as the basic research unit, the regional spatial correlation and spatial connection characteristics are analyzed on the basis of measuring accessibility, in order to reveal the evolution process of spatial structure in Beijing-Tianjin-Hebei region since 1995. On the basis of the comparison between the above conclusions and the existing planning plan of Beijing-Tianjin-Hebei area, the paper puts forward some suggestions for the spatial structure planning of Beijing-Tianjin-Hebei area. The accessibility of Beijing-Tianjin-Hebei region was measured by cost weighted grid algorithm, and the evolution of spatial pattern of accessibility in Beijing-Tianjin-Hebei region in 1995, 2003 and 2011 was analyzed longitudinally. In the regional perspective, the overall accessibility is significantly improved, but there are internal differences in the degree of improvement. Between the two towns, the accessibility level is improved, the reachability structure is improved, and the number of towns in the exchange circle increases. Based on the reachability spatial weight matrix, the edge adjacent weight matrix and the inverse distance weight matrix, respectively, the hot spots in Beijing-Tianjin-Hebei region are analyzed. It is found that the reachability spatial weight matrix can better fit the reality. The LocalMoran's I coefficients are calculated based on the reachability spatial weight matrix, and the spatial distribution and evolution characteristics of the four economic development regions in the Beijing-Tianjin-Hebei region, the mountain area, the plain region and the basin area are analyzed. The reachability modified gravity model and field strength model are introduced to study the spatial relationship between Beijing, Tianjin and Hebei. The characteristics of economic relationship between cities and towns in Beijing, Tianjin and Hebei are reflected in the two aspects of economic flow and flow. In the flow, the equilibrium situation evolves into the rapid aggregation situation, while Beijing and Tianjin are the stable core economic flow gathering places, Shijiazhuang and Tangshan are secondary sinks. In the direction of flow, the group development is obvious, the structure of one axis and two belts is gradually clear, namely, the development axis of Beijing and Tianjin and the Bohai Rim belt, and the area of Tangshan-Beijing-Shijiazhuang-Handan. The relevant conclusions of spatial association and spatial connection in Beijing-Tianjin-Hebei area coincide with Wu Liangyong's planning scheme of "one axis, three belts" and Xiao Jincheng's "one axis, two belts, three cities and four districts", and put forward some suggestions for planning the spatial structure of this area. It shows that the analysis of the spatial structure of Beijing-Tianjin-Hebei region based on accessibility is of practical significance.
