The fractal theory is adopted to analyze the fractal consistency between traffic network and urban morphology for medium and small cities,aiming at a better coordination of the two.Considering the non-uniformity from center to marginal areas,the radius dimension is used for the fractal quantitative description in order to ensure the comparison and aggregation,and the coordination factor is defined in order to measure the matching degree in the gradual changes from center to margins.On the basis of the structural and fractal characteristics of medium and small cities, a judgment standard for coordination is established and the consistency between traffic network and urban morphology is investigated. The high coincidence of experimental results and actual urban development demonstrates the feasibility of this method.%针对中小城市交通网络与城市形态的协调发展问题,采用分形理论进行了二者几何形态的分形一致性协调分析.首先,考虑到沿中心渐变的不均匀性,为确保二者分维的可比性与聚集度,采用半径维数定量描述交通网络分形和城市形态分形,定义协调因子表征二者从测算中心向外围渐变过程中的协调匹配程度,并基于中小城市的结构特征与分形特征,建立了适合于中小城市的协调匹配判断标准,对交通网络与城市形态的分形一致性展开了深入分析.研究结果与城市实际发展情况高度吻合,说明了本方法作为城市与交通协调发展研究的可行性.
