当前,城市轨道站点及周边区域综合开发相互脱节、站城融合不充分、可达性不足以及综合效益低等诸多一体化建设问题日渐凸显,且城市轨道站点的监督实施评估机制尚不完善。在搭建城市轨道站点评估体系框架的基础上,从用地功能、交通组织、空间环境、商业活力、经济效益、安全韧性、地下空间和实施成效8个维度建立了城市轨道站点一体化评估指标体系,并以北京32个轨道站点为研究对象,利用熵权—TOPSIS法开展轨道站点不同辐射范围尺度的评估及分类。结果表明,轨道站点辐射范围不同,轨道站点一体化建设的影响因素存在空间差异,通过利用K-means聚类将评估结果划分为4类,并提出了分类优化建议。
At present, many integration construction problems such as the disconnection of integrated development of urban rail stations and surrounding areas, insufficient integration of stations and cities, insufficient accessibility, and low comprehensive benefits are becoming more and more prominent, and at the same time, the mechanism for supervising and implementing the assessment of urban rail stations is not yet perfect. Based on the framework of urban rail station assessment system, this paper established an integrated assessment index system for urban rail stations from eight dimensions, including land function, traffic organisation, spatial environment, commercial vitality, economic benefits, safety resilience, underground space and implementation effectiveness, and took 32 rail stations in Beijing as the objects of study, and carried out the assessment and classification of the rail stations in different radial scales by using entropy Weight-TOPSIS method. Evaluation and classification of different radiation scales of rail stations were carried out by using entropy Weight-TOPSIS method. The results show that there are spatial differences in the influencing factors of rail station integration construction in different radiation scales of rail stations, and the assessment results are divided into four categories by using K-means clustering, and classification optimisation suggestions are put forward.
