摘　　要： 应用湘鄂两省气象代表站1961～2008年气象资料,采用30年滑动累积统计方法,分析气候变化背景下湘鄂双季稻低温冷害的变化特征。初步分析表明,近50年来,湘鄂轻度春播期低温30年滑动累积日数呈下降趋势;湖北中南部、湖南北部和西部中度春播期低温30年滑动累积日数呈下降趋势;但湖南南部呈上升趋势;湘鄂重度春播期低温30年滑动累积日数呈上升趋势。湘鄂轻度5月低温30年滑动累积日数呈下降趋势;湖北中南部中度5月低温30年滑动累积日数呈上升趋势;湖南北部、湖南南部呈下降趋势;湖南西部变化不显著;湖北中南部、湖南北部、湖南西部重度5月低温30年滑动累积日数呈下降趋势;湖南南部呈上升趋势。湘鄂轻度寒露风30年滑动累积日数呈下降趋势;湖北中南部、湖南北部和西部中度寒露风30年滑动累积日数呈下降趋势;湖南南部呈上升趋势;湖北中南部重度寒露风30年滑动累积日数呈下降趋势;湖南北部和南部未出现,湖南西部呈上升趋势。 Using the weather data in the weather representative station in Hunan Province and Hubei Province from 1961 to 2008,adopting 30 years glide accumulation method,the change characteristics on cold damage for double rice in Hunan Province and Hubei Province under the background of global climate change were analyzed.The initial analysis showed that the days of 30 years glide accumulation on low-grade cold damage in spring rice in Hunan Province and Hubei Province were declined trend during the past 50 years.The days of 30 years glide accumulation on medium-grade cold damage in spring rice in Hubei Province and the northern and western part of Hunan Province were declined trend.Ones in the southern part of Hunan Province were increased trend.The days of 30 years glide accumulation on heavy-grade cold damage in spring rice in Hunan Province and Hubei Province were increased trend.The days of 30 years glide accumulation on low-grade low temperature in May in Hunan Province and Hubei Province were declined trend.The days of 30 years glide accumulation on medium-grade low temperature in May in the middle and southern part of Hubei Province were declined trend.Ones in the northern and southern part of Hunan Province were increased trend.Ones in the western part of Hunan Province were not marked trend.The days of 30 years glide accumulation on heavy-grade low temperature in May in the middle and southern part of Hubei Province amd the northern and western part of Hunan Province were declined trend.Ones in the southern part of Hunan Province were increased trend.The days of 30 years glide accumulation on low-grade low temperature in September in Hunan Province and Hubei Province were declined trend.The days of 30 years glide accumulation on medium-grade low temperature in September in the middle and southern part of Hubei Province and the northern and western part of Hunan Province were declined trend.Ones in the southern part of Hunan Province were increased trend.The days of 30 years glide accumulation on heavy-grade low
