Total solar radiation and its distribution characteristics in Yulin region are analyzed and its potential use value is evaluated based on the meteorological observation.Results show that the best seasons for theuse of solar energy were the spring,summer and autumn.The highest value of annual total solar radiationoccurs along the Great Wall and the lowest value,in the Southwestern Dingbian County and Southern ZizhouCounty.All of the counties(district)in the region belong to the solar resource-rich area,of which the subareas of Fugu-Shenmu-Yulin-Hengshan-Jingbian-Jiaxian-Mizhi-Wubu-Suide-Northern Zizhou arein the very rich area and Dingbian-Southwest Jingbian-Southern Zizhou,in the rich area.The solar energyresources of the city are rich and stable and have a high potential? for the development and utilization.The results can provide the guidance to agricultural production,research on climate change and further use of solarenergy.
