摘　　要：石羊河流域光照资源充足,太阳辐射强,准确估算其太阳总辐射对石羊河流域农业生产具有重要意义。为了对常见太阳辐射总模型在石羊河流域的模拟精度进行评价,确定适合石羊河流域太阳总辐射估算的模型,本研究基于中国农业大学石羊河实验站2014-2018年的气象数据资料,选取5种太阳总辐射模型,采用决定系数R2、平均绝对误差MAE、均方根误差RMSE、一致性指数d以及整体评价指标GPI共5个指标进行适用性评价,并进行了基于不同天气类型的太阳总辐射模型模拟与评价。结果表明:基于日照百分率、日平均温度、相对湿度的综合模型具有最佳的模拟效果;晴天天气下,三次函数型A-P模型具有最佳模拟效果;多云天气下,综合模型模拟效果最佳,提出了基于天气组合的石羊河流域太阳总辐射估算模型,为石羊河流域太阳总辐射估算提供了进一步的模型支持。There are sufficient illumination resources and strong solar radiation in Shiyang River Basin.It is of great significance to estimate the total solar radiation accurately for agricultural production in Shiyang River Basin.In order to evaluate the simulation accuracy of common total solar radiation models in the Shiyang River Basin and determine the model suitable for the estimation of total solar radiation in the Shiyang River Basin,this paper selects 5 types of total solar radiation models based on the meteorological data of Shiyang River Experimental Station of China Agricultural University from 2014 to 2018.Five indexes,namely determination coefficient R2,mean absolute error MAE,root mean square error RMSE,consistency index d and overall evaluation index GPI are used to evaluate the suitability of the solar total radiation model based on different weather types.The results show that the comprehensive model based on percentage of sunshine,average daily temperature and relative humidity has the best simulation effect.In sunny weather,the cubic function A-P model has the best simulation effect.In cloudy weather,the comprehensive model has the best simulation effect,and the estimation model of total solar radiation in Shiyang River Basin based on weather combination is proposed,which provides a further model support for the estimation of total solar radiation in Shiyang River Basin.
