四子王旗冬季采暖期和采暖强度的变化分析

利用四子王旗1971—2015年(10月至次年4月)日平均气温资料,通过线性趋势分析方法、度日法和MannKendall方法,分析近45a四子王旗采暖强度、采暖期长度、采暖初日和采暖终日变化特征,根据《民用建筑采暖通风与空气调节设计规范》(GB50019—2003)的规定确定了理论采暖的初日和终日。分析结果表明:近45a来,四子王旗冬季采暖初日在推迟,终日无明显变化;采暖强度呈显著减少趋势,变化速率为-77.04%;采暖期长度呈现下降趋势,但是下降趋势不显著。

Analysis on the Change of Heating Period and Heating Intensity in Siziwang Banner during Wintertime

Based on the daily mean temperature data of Siziwang Banner from 1971 to 2015(from October to next April),this paper analyzes the heating intensity,length of heating period,daily variation characteristics of heating period in Siziwang Banner nearly recent 45 years by using linear trend analysis method,degree-day method and Mann-Kendall method According to the national standard‘Civil Building Heating Ventilation and Air Conditioning Design Code’(GB50019-2003),the beginning and ending days of theoretical heating are confirmed.The results show that.In the past 45 years,the beginning day of heating is delayed and the ending day of heating has not significant change.The heating intensity shows a significant decrease trend,and the rate of change is-77.04%.The length of heating period is decreasing,but the decreasing trend is not significant.
