Understanding of ecological demanding condition is conducive to analyze the supply and demanding relationship of ecosystem services and optimize land resource layout and ecological land configuration. The research was carried out from the perspective of ecosystem services demanding. Three factors were selected as evaluation indicators, including ecology economy harmony, ecological scarcity and human development. Based on the evaluation of these three separated indicators, the overall ecological demanding in Beijing City was evaluated by multicondition evaluation method, and the Beijing City was divided in to three ecoregions. The results of each indicator show that there are significant differences in ecosystem services value per capita between different districts of Beijing City. Moreover, the ecological resources become increasingly scarce from central districts to suburban districts. In the aspect of ecology economy harmony, most mild coordinated regions distribute in the ecological conservation areas which locate in the north of Beijing City, the capital core functional areas and new urban development areas are mostly on the mild conflicting level. Human development and ecological demanding gradually reduces from the downtown to the outer suburbs. The overall evaluation result presents that the ecological demanding gradually reduces from city center to outer suburbs. More specifically, the Dongcheng District, Xicheng District, Chaoyang District and Fengtai District are at high levels, Yanqing District, Miyun District and Pinggu District are at low levels, and other districts are at moderate levels. According to the characteristics of different ecoregions, the suggestions about ecological environment construction were proposed. The study of this paper can provide references for the planning and adjustment of regional land resource, deployment of ecological land and environmental protection.
