成都市TOD“137”圈层规划模式及“All in One”理念研究与实践

Chengdu TOD“137”circle planning model and“All in One”concept and practice

为更好提升开发项目全生命周期运营品质,实现业态精准定位、差异发展、可持续运营,成都市地铁率先提出“All in One”理念,即一个公共交通导向的开发(TOD)项目包含多功能复合的业态。获取了成都市已开通运营的373座轨道交通站点区域内的土地价格及兴趣点(POI)站点数据,采用局部变参数的地理加权回归模型(GWR)分析成都市轨道交通站点对周边土地的增值效应。研究结果表明,相较于传统的多元线性回归模型(OLS),GWR模型不仅拟合效果更优,还能更好地减弱标准残差的空间效应,同时描述了站点周边圈层布局与土地价值关系的空间异质性。结合4个不同级别站点的策划和规划成果进行案例分析,证明了TOD“137”圈层布局规划和“All in One”理念配合实施,对70%以上的轨道交通站点周边土地具有显著的增值效应。

In order to improve the operation quality of the whole life cycle of the development project,and realize the precise positioning,differential development and sustainable operation of the format,Chengdu metro took the lead in proposing the concept of All in One,i.e.a TOD project containing a multi-functional composite format.The land price and POI data of 373 rail transit stations in Chengdu were obtained,and the geographically weighted regression model(GWR)with local variable parameters was used to analyze the value-added effect of Chengdu rail transit stations on surrounding land.The results show that compared with the traditional multiple linear regression model(OLS),the GWR model not only has better fitting effect,but also better weakens the spatial effect of standard residuals.At the same time,it describes the spatial heterogeneity of the relationship between the layout of the surrounding circle and the land value.Combined with the planning results of four different levels of stations,the case analysis proves that the TOD'137'circle layout planning and All in One concept have significant value-added effect on more than 70%of the land around the rail transit station.
