Change of Ecological Service in Beijing-Tianjin-Hebei Region in Recent 10 Years
[Objective] To study the changes of ecosystem services in Beijing-Tianjin-Hebei Region in recent years
in order to provide suggestions for developing projects of ecological restoration and conservation and designing ecological compensation mechanisms.[Methods] Changes of land coverage were recorded and analyzed in Beijing-Tianjin-Hebei region during 2005-2015 using land cover transfer matrix analysis
leading level analysis and coverage degree analysis. 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.
