| 摘 要： | 为分析全省平均以及各气候带光能、热量、水分资源的时空变化特征,使用云南115站及6个气候带代表站1961—2018年的气候要素计算各地农业气候资源统计量。结果表明,光能资源变化以减少趋势为主,出现显著突变,各气候带太阳辐射变化可能会引起云南太阳辐射高低值中心发生变化,2009年以来辐射明显增加可能会导致太阳辐射出现新的变化趋势和突变点;热量资源一致显著增加,喜凉及喜温作物的活动积温、积温持续时间及无霜期长度均显著增加,并且呈现初日提前、终日推后的趋势,对作物生长有利;水分资源总体呈现减少趋势,尤其21世纪以来下降趋势明显,亚热带地区暖干化现象突出,干旱风险等级较高。

| Abstract: | The climatic elements of Yunnan’s 115 stations and 6 representative stations of different climate zones from 1961 to 2018 are used to analyze the spatial and temporal change characteristics of light energy, thermal energy and water resources in the whole province and in each climate zone. The results suggest that: (1) the change of light energy resources mainly show a decreasing trend, and there are considerable mutations, the change of solar radiation in each climate zone may cause the change of the maximum center and minimum center of Yunnan solar radiation, the obvious increase of radiation since 2009 could lead to new change trends and mutation points of solar radiation; (2) the thermal resources are consistently and significantly increased, the active accumulated temperature and duration of accumulated temperature of cool climate crops and thermophilic crops and the length of frost-free period all increase significantly, there is a trend that the beginning date of frost-free period is advanced while the ending date is postponed, which is beneficial to the growth of crops; (3) water resources generally show a decreasing trend, especially since the beginning of this century, warming and drying are prominent in subtropical zones, and the drought risk is high. |
