起伏地形下天文辐射分布式估算模型

Distributed modeling of extraterrestrial solar radiation over rugged terrains

实验结果显示，随着DEM栅格分辨率的降低，天文辐射逐渐增大；

The experimental result shows that simulated astronomic radiation increases gradually with the decrease of DEM resolution .

以1km×1km分辨率的DEM数据作为地形的综合反映，计算了我国全年各月天文辐射的空间分布。

Using DEM data as the general characterization of terrains , ESR quantity with resolution of 1 km × 1 km for the rugged terrains of China is calculated .

本文以黄土丘陵和秦岭高山为实验样区，以一系列不同分辨率的DEM，模拟日、月及年总天文辐射，比较其误差大小及地形分析的差异。

Taking loess hilly area and Qingling Mountain as test area , this paper studies the relationship between simulated astronomic radiation and DEM resolution through simulating daily , monthly and yearly astronomic radiation based on a serial of DEMs with different resolutions .

计算了重庆地区的天文辐射分布。

Later the paper calculated the distribution of astronomical radiation of chongqing .

四季中，地形对天文辐射影响的程度为冬季>秋季>春季>夏季。

And ( 6 ) the sequence of influence strength for topography is winter > autumn > spring > summer .

而在太阳高度角较高的夏季，天文辐射空间差异较小，7月份不同地形极端天文辐射的差异仅在16%左右；

The spatial differences of ASR are relatively small in summer where a higher sun elevation angle exists and the extreme difference of ASR for different terrains is only 16 % in July ;

在起伏地形下天文辐射分布式模型的基础上计算了重庆市各月的天文辐射的空间分布，详细分析了坡向和坡度对天文辐射分布的影响以及重庆市实际地形下天文辐射的空间分布。

The spatial distribution of extra radiation every month in Chongqing based on the calculation model of the real terrain , and labored the influence of aspect and slope on the distribution of extra radiation , and the spatial distribution of extra radiation in Chongqing were calculated .
