摘要
在分析国内外太阳辐射估算方法的基础上,建立了一种简单实用、易操作的模拟逐日太阳辐射的方法,仅需要输入站点的日照时数和地理信息.对我国不同区域9个代表站点的模拟结果与实际观测结果进行比较与统计检验,结果表明:模拟值与实测值之间相关显著(相关系数为0.81～0.93),模拟得到的晴空辐射值与多年实际观测最大值基本一致.该模拟方法的平均误差为16.5%,平均偏差、平均绝对偏差和均方根偏差分别为0.77、2.09和2.65MJ·m-2·d-1.但此方法对于特定环境区域的模拟参数还需调整.
Based on analysis of the different kinds of calculation methods on solar radiation, a simple, practical and easy operative model was built to estimate daily solar radiation in China. The inputs of the model needed were the sunshine hours and geological information of calculating stand. The simulated results for 9 representative stations in the different regions of China were compared and statistically validated with the observation values. The results showed that the simulated solar radiafions had significantly related to the observation values （R^2=0.81-0.93）. The average error of calculation was 16.5%, the average absolute and the standard deviation were 0.77, 2.09 and 2.65 MJ m^-2 d^-1 respectively. The simulation parameters needed to be adjusted in the special regions.
