| 摘 要： | 比较了3种以常规地面气象资料为基础估算太阳总辐射的气候学估算模型(晴天辐射模型、天文辐射模型和MTCLIM气候模型),并以2004年福建省仅有的福州站和建瓯站太阳总辐射实测值进行验证.研究结果表明:以晴天总辐射为基值计算太阳总辐射估算模型的精度最高,运用该模型在ARCGIS支持下对福建省太阳总辐射进行空间插值,拟合了福建省区域尺度太阳总辐射月总量和年总量的空间分布,为省区域尺度生态系统碳循环模型,水文模型及植被净第一性生产力的估算研究提供了重要的空间表达参数.

| Abstract: | In Fujian province, there are only two meteorological stations that have direct solar radiation records. Therefore, it is a need to use indirect meteorological data such as temperature, water pressure and sunshine to estimate solar radiation for the region. Three major cli- matological models were evaluated, by which we found that the model based on maximum radiation of clear day is most precise. Validated with actual measured solar radiation, the values came out of the model based on maximum radiation of clear day hardly had errors, and for 9 months, the deviation from actual measurements was almost zero. Using the estimated values based on the model, and other meteorological data, and with the help of GIS, spatial and temporal distribution of global solar radiation of Fujian Province in 2004 was simulated and revealed. The results would help the creation of models, such as C recycling model and hydrological model at regional level. |
