Abstract Taking Shenzhen subway as an example, we use Baidu Heat Map to construct a system to evaluate vitality of station service area through heat average and heat coefficient of variation. Station service area, which accounts for 15% of Shenzhen municipal area, has 38%~50% of the city population from 7:00 to 23:00, less population gather at night and more during daytime. The 166 service areas can be classified into four groups: lowbalance mature areas, low-balance developing areas, high-balance mature areas and high-balance developing areas. Their vitality characteristics are quite relevant to built environment. Mature areas have higher development density. High-balance areas have higher land use mixture. Station service areas with large-scale urban village are more likely to show high-balance. The evaluation can be beneficial to adopting available strategies for different types of station service area, and shed light on trancit oriented development (TOD) planning and design.

在“公交都市”的政策背景下, 我国城市轨道交通进入快速发展时期, “十三五”期间有50个城市纳入“公交都市”示范工程。公共交通导向式土地开发

(trancit oriented development, TOD)和公共交通站点服务区逐渐受到关注[1]。以 Cervero 等[2]提出 3D原则为代表, 轨道交通站点服务区的研究较多地聚焦
