摘要

Based on the daily meteorological data with preliminary quality-control from 94 meteorological stations in North China during 1961- 2009,the impact of climate change on energy consumption in North China was analyzed by calculating heating and cooling degree-day.It’s shown that the heating degree-days( HDDs) in most areas of North China reduced obviously during 1961-2009.The heating energy consumption tended to decrease with temperature rising and the reduction rate in the northern region was greater than that in the southern region.The cooling degree-days( CDDs) in most areas of North China in summer tended to increase.Besides the west of Inner Mongolia,the regions where the CDDs increased significantly in North China corresponded to the urban agglomerations of Beijing,Tianjin,Hebei and Shanxi.The rise in temperature made the cooling energy consumption increase greatly in most areas of North China in summer.The result from future climate projection reveals that the HDDs in most areas of North China will reduce persistently and the reduction rate in the northern region is also higher than that in the southern region.Simultaneously,the CDDs in most areas of North China in summer will continue to increase.The increasing rate in the southern region is higher than that in the northern region,and the most obviously increasing regions are located in the west of Inner Mongolia,Beijing,Tianjin,middle-southern region of Hebei,and south of Shanxi.This reveals that the cooling energy consumption in most areas of North China in summer will significantly increase due to climate warming.
