摘要
利用菏泽地区1954—2005年气温观测资料,分析了菏泽地区近50a的气温变化趋势,探讨了该地区冬季采暖初日、终日及采暖天数的统计规律。结果表明:20世纪80年代中期以来,菏泽地区冬季气温变暖已成为事实,1986年是冬季气候变暖的突变年;采暖初日、终日及采暖天数年际变化较大;1986年以来多暖冬,与1986年以前相比,采暖初日后移,采暖终日前移,采暖天数减少。对确定冬季采暖初日、终日,实施科学供暖有一定的参考价值。
Using winter temperature data during 1954-2005 in Heze, the temperature tend in the last 50 years is analyzed, and the statistical regularities of the first heating date, the last heating date, heating days are discussed. The result shows that air temperature warming has been coming into fact since mid-1980＇s in Heze and the abrupt year of climatic warming in winter is 1986; the inter-annual variation of the first heating date, the last heating date and heating days are obvious; there are more warmer winters since 1986, the first heating date becomes later, the last heating date becomes earlier and the number of heating days has decreased. It is valuable to determine the first and the last heating date and to put scientific heating into practice.
