摘　　要：基于最短距离和平均可达性模型设计,刻画了武汉市综合交通可达性空间差异,分析加入城际铁路前后可达性的变化特征;结合人口和经济属性指标,评价综合交通可达性与人口、经济的相关性。研究结果表明,可达性空间格局呈现核心一外围圈层结构,位于市中心的区域可达性最好;受历史因素,经济发展及自然条件等因素的影响,汉阳地区交通可达性与经济发展的相关性最为显著;沿着城际路线的出行单元,其可达性增强。This paper aims to comprehensively analyze the three types of roads influencing accessibility,which are the urban road networks,the subway networks,and intercity railways in Wuhan.The shortest time path model and average accessibility were applied for this purpose.We describe the comprehensive accessibility and space difference in Wuhan,and evaluate the spatial patterns of accessibility in different traffic network models.In particular,analysis of accessibility changes before and after intercity railway construction,and identify which areas are likely to improve from accessibility and traffic conditions.Furthermore,the correlation is evaluated by considering comprehensive accessibility population and regional gross domestic product to investigate the influence of urban internal traffic.The results show that the spatial pattern of accessibility is characterized by‘core-peripheral'configuration,the center has been the core region,and the transportation systems in Hankou,Hanyang and Wuchang were self-contained.As a result of history,economic and natural environment factors,the correlation between comprehensive accessibility and economic development is obvious in different regions,especially in Hanyang,the correlation is the most significant.Along the route of intercity travel unit,its accessibility enhancement,on this basis,the paper further verifies the improvement of intercity railway on urban internal traffic condition,so as to provide reference for traffic planning and urban construction.
