| 摘 要： | 本文以水稻抽穗扬花与灌浆结实两个高温敏感期为切入点,确定了水稻高温热害气象指标,并划分轻、中、重度3个等级,利用重庆34个气象站48年(1961～2008年)日平均气温与日最高气温资料,分析了水稻高温热害的时空分布.结果表明:自20世纪80年代中期以来,水稻高温热害尤其是重度高温热害的发生呈上升趋势.水稻抽穗扬花期,重庆东北部、中部、西南部高温热害较重；灌浆结实期,长江河谷地区高温热害重.

| Abstract: | This article pointed on the influence of earing-flowering stage and filling stage of the rice,determines the meteorological index of rice heat damage,and classified as three levels,mild,moderate and severe.Using the daily mean temperature and daily maximum temperature data of thirty-four meteorological stations in forty-eight years(1961-2008)of Chongqing,the heat damage on Rice spatial-temporal distribution of Chongqing was analyzed.The results showed that: since mid-1980s,the heat damage on rice was more a... |
