摘要
本文介绍了在地理信息系统(GIS)的空间数据席支持下的区域坡面太阳辐射计算方法。使用该方法,可用计算机按地表实际的地形参数计算山区地表接受太阳总辐射,直接辐射和散射辐射的日、月、年总量,揭示其空间分布规律。这对区域的自然与生态环境研宄具有更要价值。
A comfuting model of Solar radiation in mountain area based on Geographic Information System(GIS) is introduced in this paper .Radiation on sloping surface is computed by using digital spatial data of solar radiation on horizontal surface and Digital Terrain Model, composed of digital data of elevation, Slope gradient and aspect as input data.
