Research on ecosystem service supply-demand relations is necessary for effective ecosystem management, land development planning and rational allocation of resources. Two indicators, ecosystem service supply rate and supply-demand ratio, were formulated and applied in a case study to compare and map the spatial-temporal status of ecosystem services and the ability to supply these in different regions. Using Beijing-Tianjin-Hebei Region as an example, data obtained from high-resolution spatial land cover maps and stakeholder interviews were used to identify the spatial-temporal potential supply and flow of ecosystem services and human patterns. The results show that ecosystem service supply-demand ratio declined from 1990 to 2015, indicating that the overall proportion of potential ecosystem services turned into flow in the Beijing-Tianjin-Hebei Region declined. Determination of supply rate revealed that the status of ecosystem service provision in the Beijing-Tianjin-Hebei Region remained steady from 1990 to 2015. The ecosystem service supply-demand status of Hebei and Tianjin were in surplus, meanwhile Beijing was in deficit. The supply-demand situation of ecosystem services in Beijing and Tianjin became worse from 1990 to 2015. From the perspective of space, the supply and demand of ecosystem services in the northwest of Beijing-Tianjin-Hebei region was in surplus state, and the rest was in deficit state in the southeastern area except Beijing, Tianjin and Shijiazhuang. Compared with 1990, the change of supply-demand situation of ecosystem services in the northwest area in 2015 is very small, and the deficit range of supply and demand of ecosystem services increased sharply with the rapid expansion of cities such as Beijing, Tianjin and Shijiazhuang.

Key words: ecosystem service, spatio-temporal pattern evolution, supply, demand, Beijing-Tianjin-Hebei Region
