摘要
利用焉耆、和静、和硕气象站1961—2020年春季(3—5月)地面气象资料和作物生育期观测资料,采用气候趋势系数、滑动平均等方法,分析焉耆盆地春季灾害性天气特征及对农业生产的影响。结果表明:(1)焉耆盆地近60年来春季终霜日均呈提早变化趋势,霜期年际变化均呈明显的减少趋势。(2)春季寒潮天气年均1.5次,最多出现在4月,月均0.8次。(3)春季年均大风日数6.3 d,和静最多为10.2 d,焉耆为5.0 d,大风天气最多均出现在5月,年均2.8 d,3月最少。(4)春季大雾年均0.2 d,对农业生产的影响较小。
Based on the surface meteorological data and crop growth period observation data of Yanqi,Hejing and Heshuo meteorological stations from 1961 to 2020,the characteristics of disastrous weather in spring and its impact on agricultural production in Yanqi Basin are analyzed by using the methods of climate trend coefficient and moving average.The results show that:(1)in recent 60 years,the final frost day in spring in Yanqi Basin shows an early change trend,and the interannual change of frost period shows an obvious decreasing trend.(2)The cold wave weather in spring occurs 1.5 times a year,up to April,with an average of 0.8 times a month.(3)The average annual number of gale days in spring is 6.3 days/year,the maximum number of peaceful days is 10.2 days/year,and the maximum number of gale days in Yanqi is 5.0 days/year.The most gale days occur in May,the average annual number of gale days is 2.8 days/year,and the least in March.(4)The average annual fog in spring is 0.2 days/year,which has little impact on agriculture.
