中文摘要	建立了一个任意地形和实际天气条件下,能够计算大范围、长时间、高时空分辨率的太阳入射短波辐射模型,模型采用简化的辐射传输参数化方案和NCEP/NCAR资料相结合的方法,并成功应用于黑河流域2002年度每小时、1 km*1 km分辨率的总辐射、直接辐射和散射辐射的计算,所应用的地面资料仅为流域的地形信息.鉴于模型中总辐射是根据直接辐射和散射辐射推算的,而黑河流域2002年度缺乏直接辐射和散射辐射实测资料,模型采用分别位于黑河山区西水、中游临泽和下游额济纳旗3套自动观测仪器的总辐射资料进行验证,西水实测总辐射与计算总辐射的R~2=0.71,而临泽和额济纳旗R~2分别为0.90和0.91,但各站点均出现部分结果相差很大的情况.出现地域差异和部分结果相差很大的主要原因是由于总云量资料时空分辨率低造成的,另外计算和实测数据空间尺度的不一致也部分造成山区计算效果较差.
英文摘要	This paper describes an hourly incident solar radiation model under actual weatlier and terrain conditions, which could be used to calculate the long term global radiation, direct radiation and diffuse radiation flux in large regions, with high spatial and temporal resolution. Based on the parameterized radiation transfer theory, the model just uses NCEP/NCAR data and the topographical data, such as the DEM data, hill slope data and hill aspect data. The model was successfully used to calculate the hourly solar radiation with a spatial resolution of lkm 1km of the Heihe river basin with a catchment area 13 * 10~4 km~2 in the whole 2002. The coordinate is set up on Alberts projection. Because the model is based on the parameterized radiation transfer theory, there is no adjustable parameter, and the global radiation is calculated from the diffuse and direct radiation flux. But there are only global radiation data observed at the 3 automatic stations, thus we just use global radiation to calibrate the model. The 3 automatic stations respectively lie in mountainous area (named Xishui), oasis area (named Linze), and desert area (named Erji-naqi) of the Heihe river basin. The relationship between the observed hourly global radiation and the calculated series is not high at the Xishui station, with the correlation coefficient R~2 = 0. 71, and at the Linze and the Erjinaqi station, R~2 = 0. 90 and R~2 =0. 91, respectively. However, there are some calculated global radiation data is different largely from the observed data. The main reason of the result are not good is that the total cloud percent data from the NCEP/NCAR have not the high spatial and temporal resolution as the task required; another reason is that the spatial resolution of the observed data disagrees with that of the calculated ones.
