中文摘要：

利用遥感技术获取森林生态系统生物量是快速获取森林生物量的重要途径.文章以香格里拉县遥感影像图所提取的各植被指数及DEM所提取的地学因子为自变量,以云冷杉林生物量为因变量,建立多元线性回归模型.对模型的精度进行检验,选出最优模型.

英文摘要：

Using the technology of remote sensing to obtain ecosystem bimass is an important way to get forest biomass.This paper takes the vegetation indexes fron remote sensing images and geological factors extracted from DEM in Shangrila county as independent variables,and also takes spruce-fir forest biomass as the dependent variable,to establish multiple linear regressive models.The precision of the models have been examined and the optimum model has been chosen.
