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一1980’s in Heze and the abrupt year of climatic warming in winter is1986；the inter—annual variation of the first heating date，the last heating date and heating days are obvious；there are more warmer winters since 1 986．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．
