Wetland is one of the three major ecosystems of the Earth, which plays an important role in climate regulation, water supply and environmental purification. Based on the land ecological remote sensing interpretation data and socio-economic data from 1990 to 2015, this research quantitatively studied the change of ecosystem service value of different wetland types and different functions in the Beijing-Tianjin-Hebei (Jing-Jin-Ji) Urban Agglomeration and each city by modifying the ecosystem service equivalent value, and the wetland function was orientated by calculating the internal and external contribution rates of the wetland value. The results showed that: (1) The ecosystem service value of wetland in Jing-Jin-Ji Urban Agglomeration showed a trend of rising first and then wavily descending. The wetland value in 2015 increased by 2.93×109 yuan compared with 1990, mainly due to the increase of the value of river canals, reservoirs and ponds, as well as the increase of hydrological regulation value and water supply value. (2) Among the 13 cities in the Jing-Jin-Ji Urban Agglomeration, Tianjin had the highest ecosystem services value, and wetland value in the eastern coastal regions had increased. Inland cities in the south not only had a small wetland area, but their value had also declined year by year. (3) Hydrological regulation, water supply and environmental purification were the dominant functions of most urban wetlands in the urban agglomeration, while river canals, reservoirs and flood land were the main types of wetlands that provided service functions. The reduction and increase of ecosystem services value were closely related to human activities. Therefore, understanding the changing trend of wetland value and clarifying the functional orientation of wetland can not only enhance people's awareness of wetland ecological protection, but also provide scientific basis for the protection, restoration and sustainable use of wetland in the Jing-Jin-Ji Urban Agglomeration in the future.
