摘要
利用京津冀地区1961年-2015年逐日平均气温数据,分析了采暖度日(HDD)与降温度日(CDD)的时空分布与变化特征,探讨了城市化和地形对HDD与CDD的影响。结果表明:京津冀地区HDD与CDD分布具有明显的纬度特征,同时又受到地形影响。年均HDD总体表现为下降趋势,西北山地和一些城区站的下降趋势较大;CDD总体表现为增加趋势,城区上升趋势最大且年际波动较大。北京地区代表台站分析表明,不论是HDD还是CDD,均表现为城市化对近郊和城区的站点影响明显,对远郊站点影响较小。度日与海拔之间具有较好的相关性。
Using daily average temperature data from 1961 to 2015 in the Beijing-Tianjin-Hebei region,the spatiotemporal distribution and variation characteristics of heating degree days(HDD)and cooling degree days(CDD)were analyzed,and the effects of urbanization and terrain on HDD and CDD were explored.The results show that the distribution of HDD and CDD in the Beijing Tianjin Hebei region has obvious latitude characteristics,and is also affected by terrain.The overall annual average HDD shows a downward trend,with a larger downward trend observed in the northwest mountainous areas and some urban stations;The overall performance of CDD is an increasing trend,with the urban area showing the greatest upward trend and significant interannual fluctuations.The analysis of representative stations in the Beijing area shows that both HDD and CDD show that urbanization has a significant impact on stations in the suburbs and urban areas,while the impact on stations in the suburbs is relatively small.There is a good correlation between degrees and altitude.
