Evaluation Mechanism of Station-city Integration Degree of Shared Facilities in Urban Rail Transit Stations and Its Application in "Green Heart" Project

To solve the common problem that it is not shared and integrated with the surrounding large public buildings, based on the development concept of station-city integration, an evaluation system of station-city integration of shared facilities in subway stations, was put forward in this paper to investigate typical subway stations in Beijing, and to comb the current problems. Through the systematic study of its index generation mechanism, the entropy method was applied to the index weight, and the evaluation system optimized by multiple statistical regression was constructed. Taking the underground shared facilities of the Green Heart Project of Beijing Sub-Center as an example, the optimization strategy was put forward through the evaluation results.
