| 摘 要： | 根据博州地区4个测站1958—2008年的年、季日照时数资料,分析博州地区日照时数的时空变化,并对年日照时数进行Mann—Kendall突变检验,结果显示:博州地区日照时数空间分布由西向东逐渐递减,日照时数随时间变化呈下降趋势,1983年前后为日照时数发生突变的开始年,空气污染可能是日照时数下降的主要原因之一。

| Abstract: | Based on Temporal and spatial change of sunshine hour data of the 4 weather stations of Boertala Mongolia Autonomous Prefecture from 1958 to 2008,the temporal and spatial variety of sunshine hour was analyzed,and M-K test for the climate abrupt change was carried out.The results showed that the spatial distribution of sunshine hour in Boertala Mongolia autonomous prefecture decreases gradually from west to east.There was a sunshine hour appears to decrease along with time series.There was a abrupt change of... |
