摘要
调查了南京市两种行道树配置方式在夏季调节区域性气温和湿度中的不同效应。从北京夏令时8:00～18:00,在路面和绿带宽度以及交通流量等物理因素相近的条件下,单一以悬铃木成行栽植(第1类型)的中山东路和黄埔路的路中央、路边和人行道上,日气温的上升和日相对湿度的下降较慢;而在以雪松、水杉、龙柏及海桐混交成行,两边配植薄壳山核桃(第2类型)的太平北路和御道街,相对应点上的气温和相对湿度日变化较快。协方差分析的结果表明,在排除其它物理因素(测定日期、时间、测定位置和路宽等)干扰的情况下。第1类型的道路比第2类型的道路白天平均气温低1.9℃。相对湿度高10.4％。
The role of specics and planting designs of street trees in the modification of air temparature (T) and relative humidity(RH) in meso-climate were investigated. Four streets, namely, East Zhongshan Street (EZ), North Taiping Street(NT), Huangpu Street(HP) and Yudao Street (YD), were selected in Nanjing City on the basis of the comparable traffic flow and the width of the street and the green belt. The planting in EZ and HP were Type A, 'close system'. The plantings in NT and YD were type B, 'open system'. The meso-climate in four streets were significantly different and were associated with the types of street tree plantings. The increase in T and the decrease in RH in the morning was much slower in the type A streets (EZ and HP) than in the type B streets (NT and YD). Analysis of covariance indicated that the ambient temperature on average was 1.9℃ lower and relative humidity was 10.4% higher on streets with the type A plantings than those with the type B plantings.
