The Study Of Urban Rainwater Collection And Utilization Based On Qingdao

Environmental and ecological problems in the urban development process hasalways been plagued by people，and they become the outstanding problems. With thedevelopment of the city, the problem of water shortage become more apparent.Today,we have been unable to avoid a reality that is: water shortage has had a negative impacton China’s economy overall coordination and sustainable development.
