[ABSTRACT]Through observation data of daily solar radiation of Yinchuan station of Ningxia, using linear relationship between observation values of solar radiation and extraterrestrial radiation and relative sunshine duration and daylength, we obtained regional coefficients as =0.18, bs =0.62 by their linear correlation of past five years(1981-1985). Using the same method, coefficients of Guyuan region were confirmed too. Applying regional coefficients to be gotten and calculation formula of solar radiation, we validated daily solar radiation of two years(1986-1987) of Yinchuan station and four years(1991-1994) of Guyuan station through comparison with observation data, the results showed there were higher relationship because of the high square error R2=0.94 in Yinchuan and R2=0.85 in Guyuan. Simulation effect was evaluated through those methods called mean bias error, mean absolute bias error, root mean square error, mean absolute percentage error on solar radiation of Yinchuan(l 973-2006) and Guyuan(l 986-2006) stations. Results showed the root mean square error was large slightly, mean absolute bias error was not up to 13% and 17% in Yinchuan station and Guyuan station respectively. We estimated daily solar radiation of Yongning station using the related formula of solar radiation and regional coefficients and comparing with daily solar radiation of observation of Yinchuan of the past twelve years(1989-2000). The results showed there were good linear relationships in the twelve years, the minimum of correlation coefficient R2 equaled 0.88 in twelve years.
