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。
Geographic weighted regression analysis (GWR) is applied to calculate the annual solar radiation in the region. With the support of GIS technology, by using the monthly observation data of 194 meteorological observation stations, the average annual temperature, annual sunshine hours, And elevation as an influential factor, and using geographical weighted regression analysis as a calculation method, a regional annual solar radiation calculation model based on the GWR model was established. Comparing the total amount of annual solar radiation and the annual solar radiation observed in the same area calculated by the model, the maximum error between the fitted value and the observed value is 9.65% and the minimum error is 0.02%, indicating that the GWR model is established Of the region annual solar radiation calculation model has good calculation accuracy.
