摘　　要：运用美国PSU/NCAR的中尺度数值模式(MM5-V3)模拟上海有无林带冬夏温、湿和风场。结果表明:上海地区林带对上海西部大部地区夏季的平均气温有0.5℃的降幅作用,对冬季的平均气温影响不大;使上海地区冬季的平均比湿提高了0.2 g/kg左右,显示出其增湿的气候生态效应,但使上海西部夏季高比湿的范围有一定缩小;对上海地区冬夏10 m高度平均风速的影响较小。The numerical simulation of city climate effect by forest bands in Shanghai is studied. The temperature, humidity and wind fields in winter and summer of Shanghai with forest and without are simulated by using the PSU/NCAR MM5 mesoscale model. Results show that the summer mean temperature in most of the western Shanghai is reduced by 0.5 degree due to the forest of Shanghai, about 0. 2 but a weak influence in winter. The winter mean specific humidity is increased by g/kg due to the forest of Shanghai, which displays the climatic ecological effect of increasing humidity, and but in summer, only the area of high specific humidity in western Shanghai shrinks definitely. There is little influence on the mean wind field at 10m height level in winter and summer. There are some numerical simulation works in research of the regional climate effect by ecosystem at home and abroad, but the focus of the research is the role of climate affect by vegetation area.
