基于机场连接的航线网络,把某机场到其他机场的年可用货运吨位加权之和作为测度指标,分析2001~2013年间中国民用机场空侧货运可达性在时间和空间上的变化。研究结果表明:机场空侧货运可达性逐年提高,机场间可达性绝对差异变大,相对差异减小;北京、上海、广州和深圳机场的空侧货运可达性排名稳居前四;机场空侧货运可达性从大到小按指数规律迅速下降;华北区机场空侧可达性最高,新疆区机场可达性最低,东西部机场可达性差距缩小;七大区域机场可达性总体呈上升趋势,但上升幅度各异。
Based on the route network of airport connection, taking the sum of weighted annual available tonnage of cargo from one airport to the other airports as a measure index, the change of space accessibility of airside cargoes at civil airports in China from 2001 to 2013 was analyzed. The results show that the accessibility of air cargo at airside increases year by year, the absolute difference of accessibility between airports becomes larger and the relative difference decreases; the accessibility of airside cargoes of Beijing, Shanghai, Guangzhou and Shenzhen airports ranks the top four; Airport Airside cargo accessibility from an ascending order of the rapid decline in index law; North China Airport airside accessibility is the highest, Xinjiang Airport accessibility lowest, the accessibility of the airport between the east and west narrowed the gap; the seven regional airport accessibility The overall sexual uptrend, but the magnitude of its rise.
