【摘要】 针对城市轨道交通评价多局限于站点层面，未能充分考虑廊道尺度的整体性与协调性的问题，以广州2号线、3号线和5号线3条典型地铁线路为实证研究对象，从廊道视角引入节点-场所模型，利用核密度及廊道平衡量化的分析方法，系统评价和对比分析沿线站点的发展状态及潜能，并对3条典型地铁线路的未来发展提出优化策略。研究结果表明：2号线整体呈“从属”状态，节点与场所价值均偏低；3号线整体呈“失衡节点”状态，交通优势显著，但场所价值待提升；5号线整体相对接近平衡，节点与场所价值发展较为协调；建议3条线路从“廊道-站点”双尺度全面审视城市轨道交通沿线地区未来发展的需求和潜力。研究结果可为研判城市轨道交通沿线站点发展潜能及制定差异化发展策略提供参考借鉴。更多还原

【Abstract】 Existing evaluation approaches for urban rail transit predominantly focus on station-level analysis, lacking comprehensive consideration of the integrity and coordination at the corridor scale. This paper took Guangzhou’s Metro Lines 2, 3, and 5 as empirical research objects, and extended the conventional node–place model from the station level to the corridor scale, aiming to better capture spatial dynamics along metro lines. The methods of Kernel Density Estimation and Corridor Balance Quantification were put forward to systematically assess the equilibrium status and development potential of stations along these corridors, and proposes tailored optimization strategies for each. The results reveal that Line 2 exhibited a “dependent” state overall, with both node and place values relatively low; Line 3 showed an “unbalanced node” state, featuring significant transportation advantages but underdeveloped place value; Line 5 approached a balanced state, with relatively coordinated development between node and place values. The study emphasized the necessity of integrated “corridor-station” dual-scale analysis to holistically evaluate future development needs and potentials along rail transit corridors. The results provided valuable references for formulating differentiated development strategies tailored to various rail transit corridors.更多还原
