摘要

[Objective] The aim was to analyze the ground and shallow ground temperature trend in Sanhe in recent 40 years.[Method] According to the annual and seasonal average ground temperature in 2010,by dint of line charts and trend diagram,the ground temperature in Sanhe City in recent 40 years was discussed.[Result] The annual ground temperature,annual ground highest and lowest temperature in Sanhe City in recent 40 years was increasing.The lowest temperature in annual and seasonal surface temperature increased at fastest speed.The annual changes of the 5,10,15 and 20 cm ground temperature was decreasing and the 20 cm ground temperature decreased most significantly.In spring,the 5-15 cm ground temperature increased and the 20 cm reduced.In summer,the 20 cm temperature decreased significantly.In autumn,the 10 cm ground temperature enhanced fastest.In winter,the 10 cm and 15 cm temperature increase rate was large and the 15 cm temperature increased fastest.[Conclusion] The study provided reference for the influence of global warming on the ground and shallow ground temperature.
