当前大部分学者通常只研究太阳辐射大范围区域,对具体地域的研究很少;为此,对河北涞源太阳辐射的时空分布差异及应用可行性进行分析.给出河北莱阳地理位置;太阳辐射数据来源为当地气象站53599.采用Dubayyah太阳辐射估算法对太阳总辐射进行计算,把地表太阳辐射划分成太阳直接辐射、太阳散射辐射和周围地形反射辐射,采用求和方式求出总太阳辐射.给出涞源典型月份太阳直接辐射、散射辐射、周围地形反射辐射和总辐射时空分布差异分析结果,分析了涞源太阳辐射每天不同时段的时间分布差异.对太阳能资源光热转换和光电转换应用可行性进行分析.结果表明:涞源7月太阳辐射值最高,1月太阳辐射值最小,太阳能最佳利用时间为夏季中午;资源应用可行性强.%At present,most scholars usually only study salar radiation of large areas,and there is little research on specific areas. Therefore,the temporal and spatial distribution of solar radiation in Hebei Laiyuan and the feasi-bility of the application is analyzed. Given the geographical location of Hebei, Laiyang, the source of solar radia-tion data for the local meteorological station 53599. Radiation estimation method for the total solar radiation was cal-culated using Dubayyah to the sun,the surface solar radiation into direct solar radiation,diffuse solar radiation and reflected radiation surrounding terrain,calculate the total solar radiation using sum. The temporal and spatial distri-butions of solar direct radiation, scattered radiation, reflected radiation and total radiation in typical months of Laiyuan are analyzed. The temporal distributions of solar radiation in different periods of Laiyuan are analyzed. The feasibility of solar energy photothermal conversion and photoelectric conversion is analyzed. The results show that Laiyuan has the highest solar radiation value in July, the smallest solar radiation value in January, the best solar energy utilization time is noon in summer,and the feasibility of resource application is strong.
