Correction of Urban “Heat Island” Strength and Forecast of Heat Load

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.
