Abstract
[Objective]The researeh aimed to study climadc change trend in Xinetai 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 climatic vailability.Moreover,the concrete charatcteristlcs of climatic climatic trend were discussed.[Result]The annual rainfall in Xingtai City in recent 57 years presented obvious decrease trend at velocity 20.952 mm/1O a.The annual average temperature,annual average maximum temperatutre and annual average minimum temperature all presented rise trend.The rise speed of minimum temperature was the fastest,followed by average temperature.The rise speed of maximum temperature was the slowest.The annual relative humidity decreased at velocity of 1.460%/10 d.The ground temperature of 0 cm presented rise trend,but the ground temperatures of shallow layem(5-20 cm)all presented decline trend.The ground temperatures of deep layers(0.8 and 1.6 m)both presented weak decline trend.The ground temperature of 3.2 m presented obvious rise trend.The annual total cloud amout increased at velocity of 1.673 into/1O a.The annual sunshine hours decreased at velocity of 100.600 h/10 a.The annual average and annual minimum atmospheric pressures both presented decline trend.The decline trend of annual minimum atmospherie pressure was very obvious,but the annual maximum atmospheric pressure presented obvious rise trend.[Conclusion]The research provided theoretical basis for development and utilization of agricultural production resourees in Xingtai City.关键词
