摘　　要：根据世界气象组织二倍标准差和降水量距平百分率±60%标准，统计分析了广西88站1960年以来春季（2-4月）、前汛期（4-6月）、夏季（6-8月）、秋季（9-12月）和冬季（12-2月）的平均气温和降水量表明，近二十多年来，异常气候增加了，从季节看，冬季，不仅是发生异常高温和异常低温最多的季节，也是发生异常多雨和异常少雨最多的季节，更是异常气候空间分布范围最大的季节。Based on the double standard deviation made by WMO and the percentage of precipitation departure with ±60% and the temperature and precipitation data since 1960 on 88 stations in Guangxi, the mean temperature and precipitation in spring （from February to April）, in presummer flood period （from April to June）, in summer （from June to August）, in autumn （from August to September）, and in winter （from September to December） is analyzed. Results show that abnormal climate increases in the recent 20 years and the extreme high temperature and extreme low temperature with abnormal precipitation in winter is more significant than the other seasons and it is most abnormal climate season with the largest range in spatial.
