摘要

[Objective]The research aimed to study climatic change trend in Xingtai City in recent 57 years.[Method]Based on climate data(rainfall,temperature,sunshine,relative humidity and ground temperature,etc.) in Xingtai City during 1954-2010,the climatic change trend in Xingtai City in recent 57 years was analyzed by using line chart,trend chart and climate variability.Moreover,the concrete characteristics of climatic change trend were discussed.[Result]The annual rainfall in Xingtai City in recent 57 years presented obvious decrease trend,and the decrease velocity was 20.952 mm/10 a.The annual average temperature,annual average maximum temperature and annual average minimum temperature all presented rise trends.The rise speed of minimum temperature was the fastest,and was followed by average temperature.The rise speed of maximum temperature was the slowest.The annual relative humidity decreased at the velocity of 1.460 % /10 a.The ground temperature of 0 cm presented rise trend,but the shallow-layer ground temperatures of 5-20 cm all presented decline trends.The deep-layer ground temperatures of 0.8 and 1.6 m both presented weak decline trends.The ground temperature of 3.2 m presented obvious rise trend.The annual total cloud amount increased at the velocity of 1.673 into/10 a.The annual sunshine hours decreased at the velocity of 100.600 h/10 a.The annual average and annual minimum atmospheric pressures both presented decline trends.The decline trend of annual minimum atmospheric pressure was very obvious,while the annual maximum atmospheric pressure presented obvious rise trend.[Conclusion]The research provided theoretical basis for development and utilization of agricultural production resources in Xingtai City.
