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.
