摘　　要：太阳辐射是地球上最基本、最重要的能源。在实际情况下,由于地面的起伏变化(如坡度、坡向),造成地面接受太阳光的状况存在很大差异,太阳辐射在地面还存在一个重新分配的过程,从而形成复杂的太阳辐射空间分布,造成局部的小气候特征的差异。根据国内、外山地太阳辐射研究进展,研究利用ARC/INFOAML开发出山地入射潜在太阳辐射模型,实现对地面所获得太阳辐射量的数值模拟。To the Earth, solar radiation is the most basic and important energy resource .Because of the complexity of land surface (such as aspect, slope etc.), solar radiation will be redistributed on the land surface. Thus, there exists spatial distribution of solar radiation and leads to the characteristics difference in local climate. According to the development of mountainous solar radiation study in domestic and overseas ,this paper simulate the solar radiation received on surface through the incoming potential solar radiation model developed by ARC/INFO AML.
