摘  要：
提出了基于对城市低冲击开发影响(low impact development,LID)下的可持续发展策略思想,通过对不同路面(花岗岩路面、水泥路面、透水路面及草坪地面)和传统平屋顶与生态屋顶实地进行的地表温度监测对比实验,定量地阐述了透水路面、草坪地面及生态屋顶LID措施在缓解城市"热岛效应"方面的效能。结果表明,透水路面与草坪地面对地表降温较明显,生态屋顶尤其是种植灌木的屋顶相对传统平屋顶降温显著。一天中随着时间的推移,所有下垫面地表温度呈现由低到高,再由高到底的抛物线趋势,地表最高温度均出现在中午12点。平屋顶与花岗岩路面的升温速率最高,草坪地面、透水路面与生态屋顶升温速率较低。

摘  要：
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.
