摘　　要：将地理加权回归分析(GWR)应用于区域年太阳辐照量计算,在GIS技术支持下,利用194个气象观测基本站逐月观测数据,以年平均气温、年日照时数、年平均总云量以及海拔高程作为影响因子,以地理加权回归分析作为计算方法,建立基于GWR模型的区域年太阳辐照量计算模型。对比利用模型计算的区域年太阳辐照总量与同一地区观测的年太阳辐照总量,拟合值与观测值之间的误差最大为9.65%,最小误差为0.02%,表明基于GWR模型建立的区域年太阳辐照量计算模型具有较好的计算精度。With GIS technology support, taking the annual average temperature, annual sunshine hours, annual average total cloudiness and elevation obtained from 194 meteorological stations as impact factors, the geographical weighted regression （GWR） analysis as the calculation method, the regional annual solar radiation calculation model was then proposed based on GWR model. The results show that the fitting values of the regional annual solar radiation from the model has a maximum error of 9.65% and a minimum error of 0.02% when compared with the observed values of the regional annual solar radiation of the same area. This indicates that the regional annual solar radiation calculation model based on GWR has better accuracy.
