摘　　要：利用广西融安1961—2010年逐日气温和降水量数据,按2008年中国气象局颁布的"寒露风等级气象行业标准",统计该地区近50 a寒露风发生情况。结果表明,近50 a晚稻寒露风屡年发生;从危害日数和天气过程次数来看,以轻度和湿冷型为主;从危害敏感期来看,抽穗开花期影响最严重,花粉母细胞减数分裂期次之,幼穗分化期影响相对较小;从寒露风出现早晚、危害日数和过程次数来看,寒露风年际变化较大,且自21世纪以来寒露风危害呈现减弱趋势。Based on the national meteorological industry classification standard of cold-dew wind issued by CMA,the 1961—2010 daily temperature and precipitation data of Rong＇an are employed to analyze the characteristics of cold-dew wind over the past 50 years.The results show that the cold-dew wind occurs almost every year,mainly in mild and wet-cold types.During flowering stage,it is the most serious,followed by the pollen mother cells meiosis stage,panicle initiation stage is relatively light.The occurrence of cold-dew wind varies interannually,however,the clod-dew wind damage tends to decreasing since 21st century.
