摘　　要：利用郑州市1951-2007年日平均气温资料,按照国家采暖规范从气候角度上确定了符合郑州特点的采暖初终日,较规定的初、终日(11月15日至次年3月15日)有明显推迟和提前的趋势,并分析了采暖期长度及采暖期的气候变化特征,结果表明:进入90年代特别是21世纪初采暖期明显缩短,平均较80年代缩短了14 d左右。在此基础上研究了近57 a来采暖期气候条件的变化,并通过构建采暖强度、采暖指数指标,讨论这种变化对能源消耗和环境保护的影响,从科学角度提出节能的可能性。By using of daily mean temperature from 1951--2007 in Zhengzhou, according to the national standard, the climatic significance of beginning and ending data of heating periods, and there is a clear trend of delayed and early in the requirement of the early day （ November 15 -- March 15）. The length of heating periods and the variation characteristics of climate during heating periods in Zhengzhou is discussed. Based on this analysis, from 1990s to the 21st century, the heating period was significantly shorter on average than the 80＇ s about 14 days, the change of heating climatic condition in the past 57 years. New heating intensity and heating index were erected, and discussed the influence on energy con- suming and environmental protection; put forwards the possibility of energy-saving from a scientific point of view.
