摘要: 以华安县桉树林为研究对象,基于最近的2008年20块桉树林固定样地和同期Landsat5 TM影像,选用20个自变量,建立多元线性生物量遥感信息模型,并采用8个检验样本对模型进行检验,总体预估精度达到83.58%,均方误差为1.42t/hm2,利用建立的多元线性模型反演生成华安县桉树林生物量分布图,估测华安县桉树林总生物量为404 765.316t,公顷生物量为32.344t/hm2

关键词: TM, 生物量, 多元线性回归模型, 桉树林

Abstract: By taking Huaan county's Eucalyptus Plantation Biomass as an object of study,using 20 fixed sample plots in 2008 and Landsat5 TM images of the same period and selected 20 variables,multivariate linear biomass remote sensing information model was established.Eight check samples were used to test the model,and the overall forecast accuracy was 83.58%,the mean square error was 1.42 t/hm2.Eucalyptus plantation biomass distribution map was inverted by using multivariate linear model,and eucalyptus plantation biomass of Huaan county was 404 765.316t in total,and 32.344t per hectare.

Key words: TM, biomass, Multiple Linear Regression Model, eucalyptus plantation
