Abstract: The main subjects of the study for this article are Larix prinicipis-rapprechii plantation,research on biomass and carbon storage of Larix prinicipis-rapprechii plantation in Saihanwula Forest Ecosystem 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 conducted 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 model and unitary regression model is conducted.The best multiple regression model is selected,and establishment of carbon storage model developed.

Key words: Larix Prinicipis-rapprechii plantation, biomass, carbon storage, remote sensing
