| 摘 要： | 应用19532010年桓仁县逐日平均气温序列,对桓仁山区月、年的热度日（HDD）和冷度日（CDD）的变化规律进行分析,并探讨度日与平均气温的关系。结果表明,平均月HDD以1月最大,年HDD呈明显的下降趋势,其线性倾向率为-98.96（℃.d）/10a;平均月CDD以7月最大,CDD多年呈上升趋势,上升率为7.13（℃.d）/10a。年HDD和CDD与年平均气温具有较高的相关性;年际、年代际HDD与年际、年代际平均气温具有反位相变化趋势;随着气候变暖,桓仁山区HDD将趋于减小,冬季用于供暖的能源将减少,CDD将趋于增加,夏季用于制冷降温的能源将增加。

| Abstract: | Based on the mean daily temperature during 1953-2010 from Huanren Weather Observatory,the changing rules of monthly and annual HDD and CDD in Huanren mountains were analyzed and the relationship between DD and average temperature were discussed.The results indicated that the mean monthly maximum HDD was January,annual variations of HDD were in a decreasing tendency with-98.96(℃·d)/10a.The mean monthly maximum CDD was July.While those of CDD were in a increasing tendency with 7.13(℃·d)/10a.The annual HDD,CDD were highly correlated with the annual temperatures with the temperature warming,the smaller the HDD,the less the energy consumption in winter,the larger the CDD,the more the energy consumption in summer in the future. |
