摘要

[Objective]The aim was to study climate change trend in Cangzhou City in recent 38 years. [Method]Based on the climate date such as temperature,precipitation,sunshine,temperature,relative humidity,pressure,the climate change trend in Cangzhou in recent 38 years was studied by statistical analysis methods like trend image and climate tendency rate. [Result]The annual mean temperature,annual mean maximum and minimum temperature in Cangzhou in recent 38 years were increasing and the minimum temperature rose most quickly. The annual mean precipitation decreased at a rate of 45. 804 mm /10 a. The annual mean sunshine hours reduced at a rate of 104.2 h /10 a. The annual mean cloud amount reduced at a rate of 0.355% /10 a. The temperature rose at 0, 10, 15 and 20 cm,but the temperature decreased at 5 cm. Annual mean relative humidity decreased. Annual mean air pressure,mean maximum and minimum air pressure reduced and the annual mean lowest air pressure reduced most distinctly. [Conclusion]The study provided theoretical basis for the climate change in Cangzhou under global warming background.
