摘要
选用1981—2017年铜陵市气象局3—11月逐日降水量、最长连续降水日数资料,利用线性回归方法分析铜陵市连阴雨天气特征及其对农业生产的影响。结果表明,近37年铜陵市连阴雨天气过程年代际变化特征较明显,连阴雨出现次数呈现出明显减少的趋势;铜陵市连阴雨季节分布特征较明显,春季连阴雨发生次数最多,其次是夏季,秋季连阴雨发生次数最少;连阴雨天气持续时间越长,降水量越大,对农作物产生的危害也随之增加。春季连阴雨天气影响农作物春播和夏收粮油作物,而秋季连阴雨天气则会对农作物秋收秋种产生影响。
Based on the data of daily precipitation and the longest continuous precipitation days from Tongling Meteorological Bureau from March to November during 1981-2017, the characteristics of continuous rain and its influence on agricultural production in Tongling City were analyzed by using linear regression method. The results showed that the inter-decadal variation characteristics of continuous rain in Tongling City were obvious in recent 37 years, and the frequency of continuous rain showed a trend of obvious decrease. The seasonal distribution characteristics of continuous rain in Tongling City were obvious, spring continuous rain occurred the most times, followed by summer, autumn continuous rain occurred the least times. The longer the cloudy weather lasted, the greater the rainfall and the greater the damage to crops. Continuous rain in spring affected crop sowing and grain and oil crops in summer, while continuous rain in autumn affected crop harvest and sowing in autumn.
