摘    要:本文采用气候倾向率、趋势系数、距平、Mann—Kendall检验等方法,通过对滁州市日照变化的研究,结果表明:滁州市年日照时数变化总趋势是减少的,气候倾向率为-123.52h,10a,减少趋势非常明显,发生了突变。1979年是突变的开始年份,突变后减少了393.3h。季日照时数,夏季减少最快,春季减少最慢;月日照时数8月减少最快,4月减少最慢。季平均日照时数,夏季最多,冬季最少。各季节日照时数的突变特征不尽相同。

关 键 词:日照  气候特征  突变分析

Abstract:Using the rate of climate tendency, the trend coefficient, anomaly, Mann-Kdndall testing and so on studied the sunshine changes in Chuzhou. The result showed that the general trend of sunshine hours in was to reduce and the rate of climate tend was 123.52 h/10a in Chuzhou. The decline was very clear that the mutation occurs. The mutation occurred in 1979 first time. The sunshine hours reduced 393.3h after that. Quarter of sunshine hours in Summer to reduce the fastest and the slowest reduction in Spring. Sunshine hours in August reduced the fastest and the slowest in April. Quarter of the average number of hours of sunshine was the most in Summer and the least in Winter. There were different sunshine hours' characteristics of mutations in different season.
Keywords:Sunshine  Climatic characteristic  Mutation ananlysis
