    摘要:

    采用太原市1951~2003年冬季采暖期逐日氣溫資料,應用氣候方法分析了采暖期平均氣溫以及與能耗相關的采暖初日、終日、采暖度日等要素的變化特征。結果表明:采暖期氣溫存在明顯升高趨勢,而且在20世紀80年代末發生躍變;采暖初日在逐年推后,采暖終日的年代際變化振蕩較大,90年代以來有明顯提前趨勢,采暖期在逐年縮短;采暖度日存在明顯減少趨勢。結合供暖指標,分別從平均氣溫升高、采暖期縮短及采暖度日減少等方面進行節能效應分析,指出有必要改變傳統的采暖模式,城市采暖具有很大的節能潛力。

    Abstract:

    By using of daily temperature from 1951 to 2003 during heating periods in Taiyuan, the variation characteristics of mean temperatures during heating periods and elements about energy consumption (the dates of first and last days of heating periods, heating degree days, etc.) are analyzed. The result indicates that: the temperatures in heating periods increased significantly, having a jump at the end of the 1980’s; the dates of first days delayed year after year, and the dates of last days show an advanced tendency since the 1990s and remarkable interdecadal changes, thus heating periods shortened year by year; heating degree days showed an obvious decreasing tendency. Based on heating indexes, an analysis of energy saving effect is made, which shows that there is high potential in energy saving in Taiyuan and it is necessary to change the traditional heating pattern.
