中文摘要：

随着中国区域交通基础设施快速发展，可达性研究受到学界与规划界广泛关注。本文通过梳理近20年来国内外区域交通基础设施可达性研究的发展脉络，从可达性时空变化及其地域效应方面总结国内外区域交通可达性研究的各自特点与发展方向，判断未来国内相关研究主题。综合比较可知，区域交通可达性的空间格局与时空演变研究仍是国内外交通地理学的研究热点问题。国外研究评价指标丰富，空间分辨率不断提高，分析技术方法Et益多样，研究内容更趋于多元化，不断拓宽了可达性研究与应用领域。国内研究发展快，但研究指标体系有待完善，空间分辨率仍有待提高，亟待考虑交通需求与政策干预等现实因素。

英文摘要：

With the rapid development of regional transportation infrastructure in our nation, the research on ac- cessibility to transportation infrastructure has been increasingly receiving attentions from academia and scholars in planning field. This article attempts to review the literature of domestic and foreign studies on accessibility to regional transportation in the recent 20 years, summarize characteristics and prospects of the studies from the as- pects of temporal-spatial variations of accessibility and the aspects of its regional spatial effect, and predict hot topics of the related domestic research in the future. Through systematically comparing the similarities and dif- ferences of domestic and foreign research, we conclude that the research on temporal variations of regional ac- cessibility is still an important topic at home and abroad. As shown in the related foreign literature, there are nu- merous evaluation indicators; spatial resolutions of accessibility have been continuously improved; more and more analytical technique and methods are being developed. When simulating accessibility, more complex and realistic factors are taken into account, such as traffic congestion, transfer, etc. Foreign research tends to be more diversified, and continues to explore new fields and new applications, such as spillover effect, etc. In the related domestic literature, the research develops quickly and adopts foreign research methods and ideas, but more stud- ies on index system are needed and spatial resolution needs to be further improved. We should also consider more important realistic factors in accessibility research, such as traffic demand and policy intervention etc.
