城市的人为热对城市热岛的产生有重要作用 ,通过对北京冬季的居民采暖排放废热、汽车排放废热和工业生产排放废热的估算 ,制定了考虑随时空变化的北京市人为热排放清单。利用北京大学城市边界层模式对北京冬季城市边界层结构特征进行模拟 ,通过考虑和忽略人为热的排放研究北京地面温度的变化 ,并通过几种方案减少人为热的排放对缓解城市热岛作用作出评价。
Urban anthropogenic heat plays an important role to urban heat island. A heat em ission inventory was carried out for Beijing in winter which includes sources such as m otor vehicles, waste heat from industrial activities and space heating. A urban boundary layer model was used to simulate a case in Beijing in winter. The effect of urban heat island is studied by considering and ignoring urban anthropologic heat.
