The Characteristics of Land Use Around Rail Transit Stations in Tianjin, China

TOD (Transit-Oriented Development) has been widely accepted in many countries as an important spatial strategy to guide the coordinated development of rail transit and urban spatial structure. However, there is still a lack of evaluation and understanding on the TOD practices in the Chinese cities. Based on site-level land use data of Tianjin in 2019, this study aims to fill this gap by an empirical investigation on the effects of rail transit stations on land use outcomes in Tianjin, China. Land use types are identified within 500 m of rail transit stations in Tianjin. Shannon entropy is used to measure the land use diversity of these areas. Multivariate linear models are established to explore the quantitative relationship between various factors and land use diversity around stations. Our study shows that land use types around transit stations are mainly residential and commercial land. Land use diversity shows a great variation around transit stations in the central and suburban area. According to our results, The density of public transportation and the distribution of schools are positively related to land use diversity. The aggregation of residential land is negatively related to land use diversity around stations in the central area. As for the stations in non-central districts, the aggregation of business land has a significant and positive effect on the land use diversity of the station areas.
