摘要
可达性是反映城市空间关联格局的重要指标,可以度量不同区域间相互作用的难易程度,目前已经成为分析区域与区域系统集聚和扩散的一个标志。为研究国家级新区——金普新区的基础设施(道路)的建设情况,根据地理国情监测数据中金普新区的陆地道路数据,构建2015年和2016年金普新区道路网络数据集,用于精确反映区域内道路网络情况;以最直观的道路节点作为研究对象,从空间可达性视角,分析连续两年道路可达性变化情况,同时对15 min生活圈居住区生活基础设施服务情况进行分析。结果表明,2015—2016年期间,金普新区总体基础设施建设成效显著,但受地形、人口、政策及旅游产业发展情况的影响,可达性空间差异较明显,部分区域基础设施建设几乎停滞,部分区域基础设施建设完善变化较缓慢,旅游资源丰富区域发展稍快;金普新区内主要居住区15 min生活圈内基础设施丰富,居住舒适度较高。
Accessibility is an important indicator reflecting the pattern of city spatial association, which can measure the difficulty of interaction between different regions. And accessibility has become one of the symbols for analyzing the agglomeration and diffusion of regions and regional systems.In order to study the infrastructure(roads) construction of national new district-Jinpu New District, this paper constructs the road network data set of Jinpu New Zone in 2015 and 2016 according to the land road data of Jinpu New District in the geographical condition monitoring data, which is used to accurately reflect the road network situation in the region. Taking the most intuitive road nodes as the research object, this paper analyzes the changes of road accessibility for two consecutive years from the perspective of spatial accessibility, and analyzes the life infrastructure services in the residential area of the fifteen-minute living circle.The results show that from 2015 to 2016, the overall infrastructure construction in Jinpu New Zone has achieved remarkable results, but the spatial difference of accessibility is obvious due to the influence of topography, population, policy and tourism industry development. The infrastructure construction in some regions is almost stagnant, the improvement and change of infrastructure construction in some regions are relatively slow, and the development in regions with rich tourism resources is relatively fast. The fifteen-minute living circle of the main residential areas in the Jinpu New Zone has rich infrastructure and high living comfort.
