The ecological service change and its driving factors were analyzed.[Results] ① In 2015, the ecological service increased compared with that in 2005, and the ecological environment was improved significantly. ② The regions with high ecological services values were mainly distributed in Yanshan-Taihangshan ecological conservation area (mainly trees and grass) and coastal ecological protection area (mainly wetland and water). Consequently, these areas were identified as the main ecological service supply areas in Beijing-Tianjin-Hebei region. ③ The dominant types of land cover conversion were (causing changes in ecosystem services) from grass land to forest lands, from arable land to forest lands, and from arable land to grass lands. The major driving factor was the ecological policy.[Conclusion] The quality of the ecological environment is gradually improving in the Beijing-Tianjin-Hebei region during 2005-2015. %R 10.13961/j.cnki.stbctb.2018.05.035 %U http://stbctb.alljournal.com.cn/stbctb/home %1 JIS Version 3.0.0
