新疆太阳能资源及区划

The solar energy resources of Xinjiang and its distribution

分析了新疆太阳能辐射年分布状况和月分布状况。通过月总辐射分布曲线、月直达辐射分布曲线、月散射辐射分布曲线,分析了不同地区、不同月份太阳能辐射分布状况。采用三级区划指标对新疆太阳能资源进行了区划。第一级区划采用太阳能资源年总量;第二级区划采用水平表面直达辐射量(Qb)与总辐射量(Q)的比值;第三级区划采用环境温度和日照时数大于6 h的天数。通过三级区划划分了太阳能资源带、区;分析了带、区季节分布特征、日照大6 h的天数和日照气温大于10℃的天数。全面了解和掌握新疆太阳能资源状况,可为本地区的太阳能利用提供可靠的资料。

This text analyzed the annual and monthly radiation distribution of solar energy in Xin-jiang.Based on the monthly total radiation distribution curve,monthly direct radiation distribution curve and monthly diffuse radiation distribution curve,the solar radiation statuses of different re-gions in different months have been analyzed.Three grades of indexes have been used for classify-ing the solar energy resource.The first grade index is the annual total solar energy resource;the second grade index is the ratio of the direct radiation on the horizontal surface（Qb）to the total ra-diation（Q）;the third grade index is the ambient temperature and the number of days for sunshine duration over 6 hours.The solar energy resource has been divided into belts and regions by the three grades of indexes;the solar energy distribution of the belts and regions in different seasons has been analyzed,the number of days in which the sunshine duration is over 6 h and the number of days in which the ambient temperature is over 10 ℃ has also been analyzed.It gives thoroughly information of the solar energy resource in Xinjiang,and could be used as reference for utilizing the local solar energy.
