Application of LID measures in sponge city landscape design
The concept of low-impact development(LID)is one of the core elements of sponge city.Measures taken in sponge city construction include ecological grass gully,receding green space,rain garden,green roof,underground seepage storage,permeable pavement,etc.This paper mainly puts forward the application research of LID measures in municipal road landscape design from three aspects:permeable paving,grass planting ditch and rain garden,and puts forward certain reflections on the selection of plants under such measures.Through the test comparison of actual projects,it is concluded that when the retention zone standard is lower than 10.0mm/min,there is no overflow on the road,and the maximum overflow flow is only 4.95mm/min,and the corresponding infiltration volume is always stable above 5.0mm/min,which can realize the effective utilization of water resources.
