广州市城市建设用地的廊道效应分析

Analysis on the Corridor Effect of Urban Construction Land in Guangzhou City

以广州城市建设用地为研究对象,运用GIS,RS并以沿地铁网络分布的城市建设用地的变化情况为指标,分析了广州城市建设用地的廊道效应。结果表明,到目前为止,广州地铁线仅对白云区和南沙区的土地利用产生明显的廊道效应,而广州地铁站点也仅对番禺区的土地利用产生明显的分异作用,其他5个区和新增的建设用地并没有沿着地铁线或地铁站点呈现逐级递减的规律分布,即无明显的廊道效应。

Taking Guangzhou city construction land as the research object,using RS,GIS and taking the change of urban construction land as the index, the corridor effect of Guangzhou urban construction land was analyzed. The results show that, so far, the Guangzhou subway line only to Baiyun District and Nansha District land use has the corridor effect obviously,while the Guangzhou subway station is only of land use in Panyu District have obvious differentiation,the other 5 areas and new construction land and not along the subway or subway station distribution presents the gradual decreasing law,no obvious corridor effect.
