【摘要】 利用公主坟自动气象站 (供热区 )和北京市观象台 (郊区 )间 1 997～ 2 0 0 1年 4个冬季逐月 ( 1 1月～ 3月 )逐日 4次气温差值 ,研究了城市热岛变化特征 ,结合其他研究提出了北京市各供热区城市热岛强度订正原则和初步结果。对北京市 2 0 0 1～ 2 0 0 2年采暖季的室内外气象 热力试验数据进行科学分析 ,求出不同环境温度条件下单位面积供热量模式 ,按此模式运行则存在较大节能空间。更多还原

【Abstract】 The properties of urban “heat island” variation in Beijing and the correction role of urban “heat island” strength to every heating district and the preliminary results are given out according to the daily temperature difference between automatic meteorological station in Gongzhufen(representing for heating area) and Beijing Meteorological Station(representing for suburb area) during every heating period (Nov. to Mar.)from 1997 to 2001. Through scientific analysis of meteorological and heating data inside and outside for heating period in 2001—2002,a relation- model between heat load and surrounding temperature are obtained that can be put into use for saving energy greatly.更多还原
