吉林市冬季气候变化对设施农业的影响

Influence of Winter Climate Change on Facility Agriculture in Jilin City

利用吉林市气象台的气象观测资料建立时间序列,采用数理统计、趋势相关分析和MannKendall突变检验,对吉林的气温、降水和日照年序列进行了分析,以揭示吉林气候变化特征及其突变事实。结果表明,近57年来因气候变暖,吉林市冬季温度升高,气候要素变化稳定性较差。冬季气温升高、日照减少、降水量增加、连续阴雨天数增多等气象要素不稳定变化是吉林冬季气候特点,这种气候特点对设施农业影响较大。

Based on the meteorological observation data of Jilin meteorological station,the time series was established,and the temperature,precipitation and sunshine year series of Jilin were analyzed by using mathematical statistics,trend correlation analysis and Mann Kendall mutation test,so as to reveal the climate change characteristics and mutation facts of Jilin.The results showed that in recent 57 years,due to climate warming,the temperature of Jilin City in winter increased,and the stability of climate change was poor.The unstable changes of meteorological elements such as the increase of winter temperature,the decrease of sunshine,the increase of precipitation and the increase of continuous rainy days were the characteristics of Jilin winter climate,which had a great impact on facility agriculture.
