摘要
利用1954-2019年田东县国家自动气象观测站日平均气温和日最高气温资料,分析田东县水稻高温热害发生规律,并运用实时温度监测数据和短时临近预报业务平台实现对田东县水稻高温热害监测预警。结果表明,近66a田东县出现高温热害284次,年均出现4.3次,频次在波动中呈上升趋势。年代际变化中,20世纪60年代初期呈上升趋势,60年代中期至70年代初呈下降趋势,70年代中期至90年代末处在相对稳定状态,进入21世纪以来又呈上升的趋势。水稻高温热害监测预警系统在实际业务中取得良好应用服务效果。
Based on daily average temperature and daily maximum temperature of national automatic meteorological observation station in Tiandong County from 1954 to 2019,the occurrence regularity of rice heat injury in Tiandong County was analyzed.The real-time temperature monitoring data and short-term nowcasting platform were used to realize the monitoring and early warning of rice heat injury in Tiandong County.The results show that in the past 66 years,Tiandong County has experienced 284 times of heat injury,with an average annual occurrence of 4.3 times,and the frequency is increasing in fluctuation.In the interdecadal changes,there was an upward trend in the early 1960s,a downward trend from the mid-1960s to the early 1970s,a relatively stable state from the mid-1970s to the end of the 1990s,and an upward trend since the beginning of the 21st century.The rice heat injury monitoring and early warning system has achieved good application service effects in actual business.
