摘　　要：从可达性的视角采用平均旅行时间、经济潜力、日常可达性等指标对河南"米"字形高速铁路网构建对各地市省内和省际可达性及城市空间格局的影响进行分析发现,(1)"米"字形高速铁路网有助于各地市省内和省际可达性水平提升,郑州的极化与集聚效应进一步增强,边界城市的交通边缘化状况明显改善,"米"字形城镇发展轴带正在形成;(2)各地市省内和省际经济潜力大幅度提升,位置居中的高铁沿线城市省内区位优势显著,边界高铁沿线城市在省际联系中的门户区位优势显现;(3)以郑州中心的0.5 h核心圈、1 h紧密圈正在形成,"同城效应"显现,各地市省际2 h交流圈大幅度拓展,以郑州为中心的1.5 h省际合作圈即将形成。高铁网的构建将成为河南城市空间格局演变的重要推动因素和空间结构优化的基础支撑条件。Following the construction of High-speed Railway （HSR） network all over the country, temporal-spatial convergence effects of HSR will make great impacts on the evolution of urban spatial pattern, which will help the regions along the HSR to promote the optimization of urban spatial structure and reconstruction of city spatial organization mode. From the accessibility perspective, the impacts of ＂star-type＂ HSR on accessibility and urban spatial pattern in Henan Province are probed deeply using the indices of average shortest travel time, economic potential and daily communication areas. Results are shown as follows： 1） Under the construction of ＂star-type＂ HSR network across Henan Province, all central cities＇ interior-provincial accessibility level and exterior-provincial accessibility level will be significantly improved, polarization effect and agglomeration effect of Zhengzhou will be enhanced, the traffic marginalized condition of boundary cities are significantly improved, the ＂star-type＂ contact channel and urban development axis are established by the promotion of accessibility among the cities; 2） Each central cities＇ interior-provincial and exterior-provincial economic potential will be enhanced under the ＂star-type＂ HSR network, location advantages of cities located in the mid- dle of Henan along the HSR will be promoted, and gateway location advantages of boundary cities will become obviously in the process of inter-provincial contact; 3） As the center of Henan Province, Zhengzhou＇ s half an hour core communication areas and 1-hour close communication areas will be formed, one-city effect will come out between Zhengzhou and other cities surrounded Zhengzhou; Exterior-provincial 2-hour communication areas of each city are greatly expanded, Zhengzhou＇ s one and half an hour inter-provincial cooperation areas will be formed following the construction of HSR. The construction of ＂star-type＂ HSR network across Henan will be the main driving factors of urban spatial p
