Abstract Based on the analysis of the logical relationsh­ip between supply and demand of ecosystem services, this study evaluates the demand status of ecosystem services in Beijing-tianjin-hebei region, delimits the demand type areas, calculates the spatial and temporal changes of ecosystem services value (ESV) based on land use status maps in 2000 and 2015, and puts forward correspond­ing land use strategies. The result is as follows. 1) Human beings have material, environmen­tal and cultural needs for ecosystem. The demand for ecosystem services can be evaluated from four aspects: population, economic level, industrial developmen­t and educationa­l level, correspond­ing to the nine services of the four functions of ecosystem, including supply, regulation, support and culture; 2) There is a large gap in the demand for ecosystem services in Beijing-tianjin-hebei region, which can be divided into four types: extremely high demand area, high demand area, medium demand area and low demand area. 3) From 2000 to 2015, the total value of ecosystem services in Beijing-tianjin-hebei region decreased. At county level, the total value of ecosystem services and the average value of land decreased gradually from north to south in space; 4) The value distributi­on of ecosystem services in different demand areas was unbalanced. From 2000 to 2015, the value of all types of areas has decreased, and the land use strategies of different types of areas are different.
