近30年天津西青区农业气象条件变化特征分析

Characteristics of Agrometeorological Conditions in Xiqing District of Tianjin in Recent 30 Years

利用1989-2018年天津市西青区气象局近30年的气温、降水量、日照时数资料,对天津市西青区农业气象条件变化特征进行分析,以期为天津市西青区农业的健康生产提供科学指导。近30年天津西青区年平均气温整体呈波动上升变化趋势,气候倾向率为0.392℃/10年,增暖趋势较为明显;降水量在年际间波动起伏较大,极易引发旱涝灾害,给农业生产带来不利影响;四季日照时数分布较为均匀,光照条件好,有利于小麦、玉米、棉花、蔬菜等作物进行光合作用。

Based on the data of temperature,precipitation and sunshine hours from 1989 to 2018 from Xiqing District Meteorological Bureau of Tianjin,the characteristics of agrometeorological conditions in Xiqing District of Tianjin were analyzed. In the past 30 years,the annual average temperature in Xiqing District of Tianjin showed a trend of fluctuation and increase.
