摘  要:
该文以山区的高空间分辨率DEM数据为主要数据源,从中分别提取经度、纬度、坡度、坡向等相应的地形要素栅格数据,再结合多年平均的实际日照百分率资料,利用GIS技术建立山区实际太阳直接辐射的高空间分辨率分布模型,实现太阳直接辐射空间分布规律的可视化表达,分析了山区各月太阳直接辐射的空间分布特征,对于山区的农业、林业和生态环境等方面的研究具有重要的指导意义。

摘  要:
In this paper, digital elevation model(DEM) data with high spatial resolution and relative sunshine data in some years in mountainous areas were used. The topographic factors of longitude, altitude, slope and aspect, etc. were derived from DEM. With the assistance of GIS technology, the distribution model of direct solar radiation with high spatial resolution was developed to realize the visual expression of the actual spatial distribution of direct solar radiation value. The spatial distribution characteristics of monthly direct solar radiation were (analyzed). The research results have great significance to the research fields of agriculture, forestry and ecology in mountainous areas.
