摘　　要：介绍了以编程实现编制卫星图像立木材积表的过程,着重介绍了使用最小二乘法计算经验模型中参数的算法及部分代码,并以北京市密云县雾灵山的落叶松为例,利用软件建立了胸径和冠幅的一元回归模型:D1.3=3.301 4+6.312 2Ck,并据此编制了一元卫星图像立木材积表。To achieve programming of volume table of stumpage based on satellite images, the process was de- scribed in this paper, parameters and some codes in empirical model were calculated by using least squares method, and taking Larix gmelinii of Wuling moutain in Miyun country of Beijing as an example, one-variable regression model of diameter at breast height and canopy diameter： D1.3=3.301 4＋6.312 2Ck were built by using the software, and one-variable volume table of stumpage based on satellite images were compiled accordingly.

关 键 词：卫星图像 最小二乘法 立木材积表
