Abstract: To explore and utilize solar radiation in Suizhou more efficiently, and better serve local Sannong issues (namely agriculture, rural community and farmers) and ecological civilization construction, based on the percentage of sunshine and daily total solar radiation from 4 radiation stations and 16-city(county) weather stations around Suizhou, we found a suitable formula parameter for calculating total solar radiation and the monthly total solar radiation in Suizhou, and analyzed annual and seasonal spatial and temporal distribution of solar radiation with the methods of climatological calculation and space interpolation. The results showed that: the spatial distribution of solar radiation in Suizhou was less in the north and more in the south of the whole year and each season; for temporal distribution, the total solar radiation was the highest in summer, and the lowest in winter; in addition, there was a decreasing trend in total solar radiation, especially during summer. The spatial and temporal distribution of total solar radiation in Suizhou is consistent with that in China and Hubei Province. However, due to its unique geographical environment, the total solar radiation is more in south and less in north in Suizhou.
