摘要
针对利用计算机模拟模型进行森林冠层BRF模拟时,地形因子——高程、坡度和坡向对森林冠层接收太阳辐射的影响等问题,本文探讨了利用RGM(Radiosity-Graphics combined Model)模型进行森林冠层反射特性的研究,研究了将森林生长ZELIG模型和L-系统结合起来构建三维森林场景,并采用RGM模型模拟森林冠层的二向性反射特性。研究结果表明地形因子对BRF分布影响非常明显。
There were difficulties for the computer simulation method while to study the BRF（Bidirectional Reflectance Factor） distribution of the forest canopies.Terrain factor,including elevation,slope and aspect,has an impact on the vegetation of solar radiation received.Radiosity-Graphics combined Model（RGM） was applied to investigate the radiance distribution of forest canopy in this study.Combined use of the forest growth model ZELIG and L-systems to render 3-D forest scenarios,and RGM model was used to calculate BRF.The results show it is very obvious that the terrain factors have an influence on the BRF distribution.
