【摘要】：定量分析轨道交通对城市内部精细土地利用复杂变化影响的时空效应,对于预测未来新建站点对土地利用的影响以及规划方案的调整与优化具有重要的指导意义。本文提出结合历史高分遥感影像与POI数据获取多时间节点精细土地利用信息的方法,并以广州市二号和八号地铁线为例,结合逐步回归模型与站点用地功能分类,从时间和空间两个维度定量研究地铁对土地利用转变的复杂影响过程与空间差异规律。结果表明,轨道交通促使站点周边低密度居住用地向商业用地、高密度居住用地等高效益土地利用方式的转变;轨道交通在规划、建设、运营不同阶段对于周边土地利用的影响呈现显著的差异规律;地铁站点对土地利用变化影响规律具有明显的空间异质性特征,与站点在城市里的位置以及站点周边的土地利用有关,对城市中心区域的影响较小,对郊区的影响主要与可用的非建设用地面积相关,而工业用地对土地利用变化具有限制作用;轨道交通还带来用地功能和性质的转变,这样的转变大多发生在地铁站点开通运营的时间点。
[Abstract]:The quantitative analysis of the space-time effect of rail transit on the complex changes of urban land use has important guiding significance for predicting the impact of new stations on land use in the future as well as the adjustment and optimization of planning schemes. This paper presents a method of obtaining fine land use information of multiple time nodes by combining historical high score remote sensing images with POI data. Taking Guangzhou No. 2 and No. 8 subway lines as examples, combining with stepwise regression model and site land function classification, this paper proposes a method for obtaining precise land use information from multiple time nodes. This paper quantitatively studies the complex influence process and spatial difference law of subway on land use transformation from two dimensions of time and space. The results show that rail transit promotes the transformation of low-density residential land around the station to commercial land, high-density residential land and other high-benefit land use, and rail transit is planning and building, The influence of different operation stages on the surrounding land use showed significant differences, while the influence of subway stations on land use change had obvious spatial heterogeneity. Related to the location of the site in the city and the land use around the site, the impact on the central area of the city is relatively small, and the impact on the suburbs is mainly related to the usable non-construction land area. But the industrial land has the restriction function to the land use change; the rail transit also brings the land use function and the nature transformation, such transformation mostly occurs at the time point when the subway station opens the operation.
