廊道效应是交通网等产生的、由中心轴线向外随距离增大而逐步衰减的效应。目前,城市交通网络对城市建设用地的廊道效应正在受到越来越多的关注,但现有的对城市交通网络的研究主要集中在城市轨道交通和公路网络等方面,并没有考虑到人们出行越来越多采用的交通工具---地铁。因此,以广州市番禺区为研究区,运用GIS和RS分析了广州地铁对番禺区土地利用的廊道效应。先分别建立地铁线和地铁站点的缓冲区,再分别提取距地铁500 m,1000 m和2000 m范围内的土地利用信息,最后研究广州地铁沿线和沿站点的土地利用空间分异情况。研究结果表明,到目前为止,广州地铁线对番禺区的土地利用还没有明显的廊道效应,但广州地铁站点却对番禺区土地利用具有明显的分异作用。

The corridor effect is produced by transportation networks and gradually decreases from the central axis outwards, following the law of distance attenuation. The corridor effect of the traffic network on urban land use is arousing more and more attention. However, most people believe that the transportation network is mainly composed of rail and road networks, but they do not take metro into account, which is actually an increasing important transport way for people. In this paper, Panyu District in Guangzhou City was chosen as the study area. By using GIS and RS, the corridor effect of Guangzhou metro was analyzed. First, the authors made buffer for subway lines and subway stations with distance of 500 m, 1 000 m and 2 000 m. And then, the land use information in the distance was extracted. Finally, the results and statistics were displayed. The results show that so far the land-use corridor effect along Panyu metro line has not yet been obvious, but the corridor effect can be found around Panyu metro stations.
