A sustainable development strategy was put forward based on low impact development(LID).An experimental study of surface temperature monitoring on spot was implemented through the different road surfaces(granite road,cement road,permeable pavement and green ground)with the traditional flat roof and ecological roof.The performances of permeable pavement,green ground,ecological roof and other LID measures to alleviate the urban“heat island” were quantitatively described.The experiment showed that permeable pavement and green ground could cool the surface temperature more obviously.Ecological roof,especially planting shrubs roof,brought a significant decrease in temperature,as compared with the traditional flat roof.As time goes on of the day,all the underlying surface temperatures showed a parabolic trend from low to high and then high to low,and the maximum surface temperature occurred at 12:00.The heating rates of flat roof and granite road were higher than those of green ground,permeable pavement and ecological roof.
