Where and how to restore wetland by utilizing storm water at the regional scale: A case study of Fangshan, China

Wetlands have multiple functions such as biodiversity protection, hydrological regime reduction, pollution sediment filtration, and tourism service etc., though wetland areas have been shrunken and fragmented largely recently, especially where nearby cities. A great application significance can be o...
