Abstract: To explore the coupling coordination relationship between metro station construction and public service facility layout, 10 community metro stations in Tianjin are selected as research objects. Guided by the ′5D′ principle of TOD (transit\|oriented development) theory, a multi\|dimensional coordination evaluation index system of density, diversity, accessibility, transportation convenience, design and balance is constructed. Based on multi\|source data including population density, POI (point of interest) and built environment, analysis methods such as GIS (geographic information system) kernel density, grid cost distance, information entropy are adopted to comprehensively evaluate the coordination of station site and surrounding public service facility layout. Finally, optimization suggestions are put forward. Research results show that: ①The number of bus stops and the location entropy indexes of public service facility are the most significant indicators that affect coordination. ②According to comprehensive evaluation score, the 10 typical community station sites can be divided into three levels of high, general and low coordination types. Each station site has its own advantages and shortcomings in each index.
