Abstract: Ecosystem service is a bridge for investigation of the relationship between man and nature. However, nature does not always provide benefits to human being. More than often, it provides as well detrimental impacts through disasters such as earthquake, tsunami, ice, sand storm, flooding, drought, soil erosion, fire, disease and biological intrusion. It is especially the case when human being overused natural resource and deteriorated environment, which will result in negative impacts on human being. On the other hand, human being does not always destroy nature in his long history of exploitation of earth, but sometimes play a beneficial role to its environment. Lots of research results showed that an appropriate interruption of nature will enhance the productivity and sustainability of nature ecosystem. The benefits provided by human being through ecological design, engineering and management could be considered as the human eco-service contributed to nature. This paper expanded the concept of ecosystem service to ecological service, which has both beneficial and detrimental effects and provided by either nature or human society. It is divided into five categories: supply, cultivation, circulation, regulation and support. Cases for eco-service measurement through equivalent land, water, energy and greening are introduced and discussed.
