摘　　要：从特大城市多核结构中心区的分析入手,通过对大量基础条件相近的中心区案例的详细调研及量化比较,从中心区交通输配体系的相关概念、级配构成等方面分析多核结构模式中交通输配体系的连结效率、通达效率、经济效率和荷载效率等特征指标,并对其进行综合评价.根据评价分值将其划分为相应的高效发展模式、中效发展模式及低效发展模式.在此基础上,进一步分析输配体系与中心区主要构成部分主核、阴影区及边缘区的相互关系,并据此提出基于多核结构模式的中心区输配体系结构,进而揭示中心区多核结构发展演化的深层次规律.To analyze the structure of multi-core central district,the survey and quantitative compari-son of a large number of central districts were adopted.The related concept and the gradation com-position of the traffic distribution system were studied.Moreover,characteristics indicators such as the link efficiency,the accessibility efficiency,economic efficiency and loads efficiency of the traf-fic distribution system were analyzed,then comprehensive evaluation of the four indicators is made. According to the evaluation scores,the central districts were divided into highly efficient develop-ment model,a medium efficient development model and a low efficient development model.On this basis,the relationship of the main core,shaded areas and marginal zone of the central district were analyzed and then a proposal of the structure of the traffic distribution system was made.Moreover, the regular pattern of the evolution process of the multi-core central district was revealed.
