机场可达性是机场建设和规划的重要指标。本文讨论了可达性研究中的参数设置与计算方法,并采用我国2009年县级数据计算和对比了不同方法得到的机场人口覆盖率。结果发现不同方法得到的结果存在较大差异,所反映的机场服务水平的空间格局也有差异。本文进一步讨论了其对机场规划的启示。
Airport accessibility represents its geographic service level and it is a key indicator for airport planning. This paper discusses the key parameters for accessibility calculation, and com- pares the different results of airport accessibility from different methods. It finds that the results getting from different methods have large differences, so as to the spatial pattern of the airport service level. The results are heuristic for airport planning and policy making.
