Ecological civilization represents the progressive state of the relationship between human beings and nature. Because ecological carrying capacity studies compound ecosystem of nature, economy and society, reflecting the harmonious degree between human beings and nature, it can be used as one of assessment methods of ecological civilization. Based on analysis of the definition and research methods of ecological carrying capacity, this study proposes the concept and assessment model of Ecosystem-Service-based Ecological Carrying
