Abstract: The paper aims to understand the temporal and the spatial distribution of solar resource in Shigatse and rational layout of agricultural structure in local condition, and increase the crop yield with the usage of solar resources. Based on the sunshine duration, sunshine percentage and the maximum temperature at 7 meteorological stations during 1985-2014 and solar radiation data of Shigatse District during 2010-2014, this paper estimated the annual total solar radiation in Shigatse on the basis of its calculation formula, analyzed the temporal and spatial distribution of solar energy and potential of solar resource in recent 30 years. The results showed that: most of the regions in Shigatze had rich solar energy resources, thereinto, Tingri, Gyantse, Shigatse District and Lazi were the richest solar resource districts with long sunshine duration and strong solar radiation, followed by Namling, Nyalam and Parry with abundant solar energy resource; the annual total radiation and sunshine duration displayed a decreasing variation trend during 1985-2014 while the decreasing trend of sunshine duration presented a more obvious variation than that of the annual total radiation; the number of days with the daily sunshine duration more than 6 h were about 263~327 days at 7 stations in the past 30 years; the number of days were more than 290 days at most of stations; the solar resource was quite stable in the southern part of Shigatse, the western part of Shigatse and areas along the Yarlung Zangbo River. As a whole, the regions with stable solar energy resources have the highest total radiation and the longest sunshine duration.
