摘要:
利用广西双季稻区1961-2016年逐日气象资料和1986-2016年水稻物候观测资料，运用气候倾向率等方法研究气候变化背景下广西双季稻低温冷害演变特征。结果表明：（1）广西水稻生育期低温阴雨、五月寒、寒露风平均频率分别为84%、41%、81%，三种低温冷害的高值区均在桂北稻区，低值区一般出现在沿海地区。（2）广西绝大部分县区水稻低温阴雨总次数、总天数、强度呈微弱减少趋势；大部分县区水稻五月寒呈微弱减少趋势。（3）桂北稻区以及桂中、桂南稻区的部分县区寒露风总次数呈微弱增加趋势，其余县区寒露风总次数呈微弱减少趋势；绝大部分县区寒露风总天数及强度呈微弱减少趋势。（4）低温冷害年平均出现总次数、总天数、强度均是桂北 > 桂中 > 桂南，三个稻区低温冷害中五月寒强度最小，桂南、桂北稻区寒露风强度稍比低温阴雨强度大，桂中稻区则是寒露风与低温阴雨两者强度相近。
Abstract:
Based on the daily meteorological data from 1961 to 2016 and the rice phenological observation data from 1986 to 2016, the chilling injury evolution characteristics of double-cropping rice in Guangxi under the background of climate change were studied by using the methods of climate tendency rate. The results showed that(1) the average frequency of low temperature rain, cooling in May and cold dew wind were 84%, 41% and 81%, respectively. The high value areas of these three chilling injuries were all in the rice area of Northern Guangxi, and the low value areas were generally in the coastal areas.(2) The total frequency, total days and intensity of low temperature rain in most rice regions of Guangxi showed a weak decreasing trend; cooling in May in most counties also showed a weak decreasing trend. (3) The total number of cold dew wind in northern Guangxi and some counties in central and southern Guangxi showed a weak increasing trend, while the rest showed a weak decreasing trend; the total days and intensity of cold dew wind in most counties showed a weak decreasing trend. (4) The average annual frequency, total days and intensity of chilling injury in north Guangxi > central Guangxi > south Guangxi. The chilling injury intensity of cooling in May was the smallest in the three rice areas. The chilling dew wind intensity in the south and the north of Guangxi was slightly higher than low temperature rain; in central Guangxi, the chilling dew wind intensity was similar to low temperature rain.
