根据沧州市1971-2010年逐年、各季地温资料，采用差值法、折线图、气候变率等分析方法，对40年来沧州市地温变化趋势进行分析，发现沧州市近40年地面温度、地面最高温度、地面最低温度年平均值分别为14.8、29.3、6.5℃；地面温度四季气候变率只有秋季是降温趋势，各月气候变率、年气候变率均为上升趋势，近40年年代际变化呈波状变化；地面最高温度四季气候变率只有春季是升温趋势，各月气候变率为上升趋势，年气候变率为下降趋势，近40年年代际变化呈线性变化，总体下降趋势；地面最低温度四季气候变率均为升温趋势，以秋季升温速度最快，各月气候变率、年气候变率均为上升趋势，近40年年代际变化呈线性变化，总体呈上升趋势。

According to the data of mean ground temperature for all years and seasons in Cangzhou City from 1971 to 2010 ,using the difference method,line graph and climate change rate analysis method ,the ground temperature change trend during recent 40 years in Cangzhou City was analyzed.The result showed that the annual ground temperature ,annual ground highest and lowest temperature in Cangzhou City in recent 40 years were 14.8 ℃,29.3 ℃,6.5 ℃ respectively.Climate variability of ground temperature decreased in autumn ,the others showed rising trends.Interannual variation showed wavy distribution;Climate variability of the highest ground temperature increased in spring. The climate variability of each month showed an ascending trend ,the change rate showed a declined tendency in the last 40 years ,and interannual variation was a linear change;Climate variability of the lowest ground temperature increased ,and that of the autumn increased most significantly.The climate variability of each month and year both increased.Interannual variation was a linear change for 40 years ,and showed increasing trend in general.
