摘　　要：太阳能具有清洁环保、可再生等优势,未来发展潜力巨大,前景广阔。以冀西北地区中心城市张家口市为例,对1956-2019年间张家口市日照时数变化进行分析,并利用全自动跟踪太阳辐射仪对紫外光和可见光辐射量进行分析。结果表明:1956-2019年间张家口市日照时数呈现先下降再上升的趋势,但是通过M-K突变检验呈下降趋势;紫外光和可见光辐射量呈现夏季高,冬季低的特点,同时受到天气的影响而存在波动;可见光包含的三种色光辐射量所占比例不同,且占可见光的比例在全年中的变化趋势存在差异。Solar energy has the advantages of clean environmental protection,renewable and so on,and has great potential for future development and broad prospects.Taking Zhangjiakou,the central city of northwest Hebei as an example,the variation of sunshine hours in Zhangjiakou from 1956 to 2019 was analyzed,and the ultraviolet and visible radiation was analyzed by using automatic tracking solar radiometer.The results show that the sunshine duration in Zhangjiakou from 1956 to 2019 showed a trend of first decreasing and then increasing,but showed a trend of decreasing through M-K mutation test.The UV radiation and visible radiation are high in summer and low in winter,and fluctuated under the influence of weather.Visible light contains three kinds of color light radiation in different proportions,and the proportion of visible light in the change trend of the whole year is different.
