摘要
河西地区是一特殊的自然地理区域，有气候干燥、荒漠地理景观和地形狭窄等三大特点。本文利用河西地区东部的民勤和西部的敦煌二个日射站的三年（1981－1983年）资料，计算了各种因子对散射辐照应的贡献。
Hexi is a special physiographical area. It is characterized by arid climate, desert landform and narrow topography. The contributions of various factors forming scatter are calculated with the data of Minqin Meteorological Station in the east and Dunhuang Meteorological Station in the west of Hexi area from 1981 to 1983. The results show that the contribution of coarse particle (Mie scatter) is the first, which takes for 3456 of annual scattering irradiation, both of the cloud and molecule 28%, the great coarse particle drifted by wind 10%. The maximum value of monthly scattering irradiation appears in May, and the aerosol has the most contribution, then, cloud and molecule.
