摘要
城市发展带来下垫面性质的变化﹑空气污染和人为废热的大量排放,使得城市热岛效应作为全球性的环境问题逐渐受到重视.城市中的绿色廊道是城市生态基础设施的组成部分,对城市小气候起着重要的调节作用,通过这种线性的绿色空间保护城市生态环境的做法已经被广泛实践于许多城市中.利用气象预报软件WRF及其耦合的城市冠层模式(UCM,Urban Canopy Model)对上海市夏﹑冬两季(7月和12月上旬)的城市温度及规划中的市域性绿色廊道对城市温度的影响进行了数值模拟.研究表明绿色廊道对缓解夏季上海市内陆地区城市热岛效应有明显的作用.研究同时证明了气象预报软件WRF-UCM可对城市尺度下的温度进行有效模拟,今后可应用于对城市土地利用规划﹑建设规划﹑生态保护规划等相关规划的环境影响评估中,提高规划和决策的科学性.
The Urban Heat Island,as a global environmental problem,is drawing people’s attention with the rapid development of city.The green corridor in the city is part of the urban ecological infrastructure,which plays an important role in regulating the urban microclimate.The method of protecting this linear green space has been widely practiced in many cities.The meteorological forecast software WRF-UCM was used to simulate the urban temperature in the seasons of summer and winter in Shanghai(early July and December)and the influence of the planning urban green corridors on the city temperature.Research showed that the green corridors have obvious effect on mitigating urban heat island effect in the inland area of Shanghai in summer.The study also proves that the meteorological forecast software WRF-UCM can effectively simulate the temperature under the urban scale,and can be applied to the environmental impact assessment of urban land use planning,construction planning,ecological protection planning and other related planning in the future,so as to improve the scientificity of planning and decision-making.
