根据2015-2016年同期平江县逐日降水量资料,利用相关检验、分析等技术方法,对平江县内的水稻受洪涝灾害及年降水量变化影响的特征进行了分析。结果表明,洪涝对水稻产量影响的关键生育期和致灾因素,同时得出在抽穗开花期遭受暴雨洪涝对水稻产量影响最大,充分考虑洪涝灾害和早稻发育期抗灾力的不同影响,为我县早稻生育过程中开展气象服务提供参考依据。
Based on the daily precipitation data of Pingjiang County in 2015-2016, this paper analyzed the characteristics of flood and waterlogging disasters and the changes of annual precipitation in Pingjiang County by using the relevant test and analysis methods. The results showed that the key growth period and the disaster-causing factors of the impact of flood on rice yield, at the same time, it was concluded that the heavy rain and flood at heading and flowering had the greatest impact on the rice yield, taking into account the different impacts of flood disasters and the resilience of early rice during development. Provide reference for carrying out meteorological service in the process of early rice growth.
