摘要
针对当前城市出租车服务站布局与城市形态之间的协调性分析缺乏定量研究的情况,提出了量化分析方法,可有助于提高出租车服务站布局的合理性与适用性.通过分形理论,分析了出租车服务站布局在城市空间内的向心聚集度、分布均衡性和方向协调性,提出了半径维数、网格维数和方向维数三类分形维数.引入分形维数的数据标准化,建立了分形协调性指数与综合指数,用以代表出租车服务站布局的空间分布特征,可有效量化分析并评价出租车服务站布局与城市形态之间的协调性.以柳州市出租车服务站选址布局为例,验算了该方法的合理性及可行性.
In view of the lack of quantitative research on the coordination analysis between taxi service station layout and urban morphology,the quantitative analysis method was proposed.At first,three kinds of fractal dimensions:the radius fractal dimension,grids fractal dimension and directions fractal dimension were put forward based on fractal theory to analyze the centripetal aggregation degree,balanced distribution and direction coordination of taxi service stations layout in urban space.Then by using the data standardization for fractal dimensions,the coordination index and composite index of taxi service stations were established to represent the spatial distribution characteristics of taxi service stations layout.These indexes were effective for the quantitative evaluation and analysis of the coordination between taxi service stations layout and urban morphology.Finally,taking the layout of taxi service stations in Liuzhou as an example,the rationality and effectiveness of the method were verified.
