摘　　要：利用康保县1960~2018年逐日气温、降水量资料以及1960~2016年逐日日照时数、风速资料,采用气候倾向率法和M-K突变检验法对康保县气候变化特征进行分析和研究。结果表明:康保县年平均气温呈显著上升趋势(P<0.01),倾向率为0.383℃/10 a,2月和3月升温最快,在1993年发生突变;降水量波动较大,倾向率为1.09 mm/10 a,变化不明显;年日照时数呈显著下降趋势(P<0.01),倾向率为-41.4 h/10 a,其中第二季度和第四季度降低较为明显,在1998年发生突变;年平均风速显著下降趋势(P<0.01),倾向率为-0.37 m/(s·10 a),其中除7、8两月外风速均在3.29 m/s以上。Based on the daily temperature and precipitation data from 1960 to 2018 and the daily sunshine hours and wind speed data from 1960 to 2016 in Kangbao County,its climate change characteristics were analyzed and studied by using the climatic tendency rate and M-K mutation test.The results showed that the annual average temperature in Kangbao County had a significant upward trend(P<0.01)with a tendency rate of 0.383 C/10 a,in which the temperature increased fastest in February and March,and mutation occurred in 1993;precipitation fluctuated greatly with a tendency rate of 1.09 mm/10 a,and the trend was not obvious;annual sunshine hours had a significant downward trend(P<0.01)with a tendency rate of-41.4 h/10a,in which the second quarter and the fourth quarter were more obvious,and mutation occurred in 1998;the average wind speed significantly decreased(P<0.01)with a tendency rate of-0.37 m/(s·10a),in which the wind speed was above 3.29 m/s except in July and August.
