摘要
研究目的:针对目前国内城市轨道交通网络规划过程中对线网与城市形态之间协调性分析主要限于定性分析的情况,通过本文的研究提供量化分析手段,有助于构架合理的轨道交通线网。研究结果:提出了轨道交通网络中位点与城市重心的吻合度、轨道交通网络分形维度与城市分形维度的一致性指数、轨道交通与城市人口在方位上的相似度3个量化指标。基于这三个定量化指标建立了轨道交通网络与城市形态的综合协调指数,确立了城市轨道交通网络与城市形态之间的协调性量化分析的方法,并以西安市城市轨道交通网络规划方案为例,分析了4个预选方案与城市形态之间的协调性。计算结果显示4个预选方案的综合协调指数分别为0.782 9、0.777 8、0.690 8、0.784 9,表明预选方案四与城市形态最为协调。
Research purposes： At present, the coordination analysis between rail transit network configuration and urban form was restricted to qualitative method during urban rail transit network planning in China. A means of quantitative analysis will contribute to building a reasonable rail transit network.
Research results：Three quantitative indexes were put forth such as the fitness between urban rail transit network middle and city gravity centre, the fractal dimension identity between urban rail transit network and urban form, and the direction coordination between urban rail transit and city developing. Based on these quantitative indexes, a compositive coordination index was built to quantitatively analyze the coordination between rail transit network configuration and urban form. Take Xihn urban rail transit network planning for instance, the coordination between it is four pre - selection networks and urban form were analyzed. These compositive coordination indexes of four pre - selection network were 0. 782 9, 0.777 8, 0. 690 8, 0.784 9, the computing results showed that the forth network is the best one.
