Abstract:Ecological infrastructure is a necessary set of conditions and combinations for maintaining, improving and increasing ecosystem services, including natural and semi-natural systems such as urban green space, wetland, farmland, biological retention pool, green roof, etc., which is the important support and guarantee of urban sustainable development. The core function of ecological infrastructure is to guarantee the normal operation of urban ecological functions and continuous access to ecological services of its residents. The paper first analyzed the definition and connotation of ecological infrastructure, and the ecosystem services provided by ecological infrastructure at regional and urban/community scale were combed from 4 aspects including provisioning services, regulating services, cultural services and supporting services. The services and technologies of runoff retention, water purification, and climate regulation of ecological infrastructure were discussed. Then the applicability and limitations of evaluation methods of ecological infrastructure services including physical, value and emergy assessment methods and model simulation were summarized. Finally, the research prospects of ecosystem infrastructure based on ecological service were put forward:(1) The interaction and coordination planning of ecological infrastructure at different scales; (2) Ecological infrastructure intelligent monitoring system based on Internet of Things technology; (3) The comprehensive evaluation methods of ecological infrastructure service based on landsenses ecology.
