Abstract:To understand the ecological mechanisms of ecological services will provide basis for ecosystem service management. However, there exists little information from the ecological mechanism research of ecosystem services. According to the basis of ecosystem services (habitat, ecosystem structure and ecosystem process), the following three works were conducted: the relationships between biodiversity and ecosystem services, the tempo\|spacial scale attributes of ecosystem services and the effects of climate changes and land\|use changes on ecosystem services. The above progresses on ecological mechanisms of ecosystem service were summarized and the problems that need to be studied further in the future were also put forward.
