Abstract：Roof greening substrates could not only support the growth of plants,but also play a key role in the ecological function of roof greening system.Replacing minerals and natural materials(perlite,vermicu-lite,peat,etc.)with recycled and reused resources as roof greening substrates is a potential solution to reduce overexploitation of natural resources and promote waste recycling.In this study,the domestic and foreign re-searches on the application of roof greening substrates converted from recycled and reused resources were sys-tematically introduced.The types and characteristics of the main recycled and reused resources used to be sub-strates were analyzed.The responses of growth and development of roof greening plants to different substrates converted from recycled and reused resources were summarized.The ecological effect of roof greening sub-strates from recycled and reused resources were summarized and analyzed,including rainwater storage and purification,thermal regulation,carbon sequestration capacity,biodiversity and so on.And the future research directions were prospected,such as the ecological effect,the potential risks,the exploitation of raw material types and the most suitable ratio of substrates from recycled and reused resources.This paper could provide some references for further research and practice of substrates converted from recycled and reused resources.
