Continuous supply of ecosystem services are the material basis for sustainable development of nature and society, which means that human being’s needs and consumptions for ecosystem services must below the range of the maximum ecological carrying capacity. As a result, the evaluation of ecological carrying capacity is closely connected and inseparable with the research of ecosystem service supply and consumption. In this paper, on the basis of existing research, the concept, evaluation indicators and methods of ecological carrying capacity based on the supply and consumption of ecosystem services were proposed, and Yanqing District was selected to do case study.
The results show that: (1) The ecological carrying capacity of different ecosystem services in Yanqing District varied a lot. water resource supply services, oxygen release services, COD and SO2 purification services ，Food supply services except vegetable oils were all in surplus situation. In contrast, ammonia nitrogen, NOX, smoke and dust purification services and carbon fixation services were overloaded. (2)Neglecting food supply service, only four towns such as Zhenzhuquan, Dazhuangke, Sihai and Qianjiadian in Yanqing were not overloaded, other villages and towns were all overloaded. The seriously overloaded areas were mostly located in plain areas with dense population and urbanization.
