以华北落叶松人工林为研究对象，对赛罕乌拉生态系统定位站内华北落叶松人工林生物量及碳储量进行研究。应用Landsat TM影像，提取遥感影像各波段信息及相关的植被指数。将遥感影像的波段信息、相关的植被指数分别与野外实测的样地生物量数据进行一元回归分析，建立一元回归模型，分析比较后得出由波段信息建立的一元回归模型较合理；将提取的波段信息、植被指数分别与野外实测样地生物量数据进行相关分析，然后采用逐步回归的方法进行多元回归分析，建立森林生物量多元遥感回归模型；将选择出的一元回归模型与建立的多元回归模型进行对比分析，最后得到适用于研究区森林生物量研究的最优遥感回归模型， Y＝-1617.863＋573.312×SAVI＋32.475×TM5-35.379×TM7，进而得到碳储量遥感模型。

The main subjects of the study for this article are Larix prinicipis-rapprechii plantation,re-search on biomass and carbon storage of Larix prinicipis-rapprechii plantation in Saihanwula Forest Eco-system Research Station.This paper employs TM images for extracting bands of TM images and related vegetation indexs.Univariate regression analysis between bands,vegetation indexs and biomass is con-ducted and the unitary regression model is constructed,and the models are scientific and rational;The correlation analysis between bands,vegetation indexs and biomass is done.Step wise regression is used and equation of multiple linear regression established.Comparative Research on multiple regression mod-el and unitary regression model is conducted.The best multiple regression model is selected,and estab-lishment of carbon storage model developed.
