【摘要】 以地形特征及周围地形遮蔽状况、经纬度位置等作为影响太阳辐射空间分布差异的变量,在地理信息系统(GIS)支持下,建立黄土丘陵沟壑区数字高程模型(DTM)和太阳辐射值计算模型,并实现理论太阳辐射值空间分布的可视化表达。更多还原

【Abstract】 using the topographic feature and the shading situation nearby and the position of longitude and latitude as the variation that effects the spatial distribution diversity of solar radiation,the author es-tabishes DTM of yellow earth hill and ravine region and the computer model of solar radiation value with the assistant of GIS to realize the visual expression of the theoretical spatial distribution of solar ra-diation value.更多还原
