以综合考虑天空因素和地面因素的起伏地形下太阳直接辐射分布式模型为基础,采用1∶25万高分辨率数字高程模型(DEM)数据和气象站观测资料,计算了100 m×100 m分辨率的浙江省气候平均月太阳直接辐射以及年直接辐射的精细分布,并分析了起伏地形下浙江省太阳直接辐射的逐月变化规律。结果表明:浙江省太阳直接辐射量以7、8月份最高,1、2月份最低,全省气候平均年太阳直接辐射量为2 083 MJ/m2;地形因子对起伏地形下浙江省太阳直接辐射的影响程度具有随季节变化的特性;局地地形对太阳直接辐射的影响程度随季节而变,在冬半年,太阳高度角较低的季节,局地地形的影响较为显著。

Direct solar Radiation (DSR) is the key component of the global radiation reaching the Earth. The DSR quantity reaching the rugged terrain is the compositive action results of sky and terrain factors. Based on a distributed model, with DEM data of 1:250 000 scale and routine meteorological data as input, normals of monthly and annual DSR quantity with the resolution of 100 m×100 m over rugged terrains of Zhejiang province were simulated and their spatial distribution characteristics were analyzed. Surface and atmospheric factors were all considered in the used model. The results suggest that DSR in Zhejiang province reaches the highest quantity in July and August and the lowest in January and February; the normals of annual DSR quantity is 2 083 MJ/m2; the influences of local topographic factors on DSR are changing with seasons and are more obvious in cold seasons that have a lower solar elevation angle.
