摘要: 利用1961—2010年沈阳市的年平均气温和供暖期及供暖期前一个月、供暖期后一个月的逐日平均气温资料,采用线性趋势分析方法及度日法,分析近50 a沈阳市年平均气温和供暖期平均气温变化的总体趋势,并对供暖初日、供暖终日和供暖期长度及供暖强度的变化特征进行分析。结果表明:近50 a沈阳市年平均气温与供暖期平均气温均呈上升趋势,近50 a年平均气温上升明显,通过了显著性检验;气候变暖使得供暖初日推迟;供暖终日提前;供暖期长度缩短;气候变暖使实际供暖强度逐渐减弱。

Abstract: Based on the annual mean air temperature data and the daily mean air temperature data of the one month before heating and after heating from 1961 to 2010 in Shenyang, the annual mean air temperature trend and mean air temperature trend of heating period were analyzed using methods of a linear trend and a degree-day. The beginning date and ending date of heating, heating duration and heating intensity were discussed. The results show that the annual mean air temperature and mean air temperature of heating are in increasing trends from 1961 to 2010, especially the former and it passes the significance test. The beginning date of heating is put off because of climate warming, and the ending date of heating is in advance. The heating duration is shortened. The climate warming makes the heating intensity decreasing.

Key words: Climate change, Average air temperature, The beginning date of heating, The ending data of heating, Heating duration, Heating intensity
