摘要
森林生物量是指林分在一定时间内累积的有机质总量,通常用单位面积或单位时间积累的干物质量或能量来表示,单位g/m2或t/hm2。本文以2007年landsat 5 TM遥感影像为数据源,以塔河林业局作为研究区域,在固定样地数据基础上,建立了研究区域内七个主要树种的生物量模型,并尝试应用TM影像与对应样地的数量关系,建立多元线性回归模型来估算研究区域生物量。
Forest biomass is the total cumulative organic matter within one year in the forest and was usually computed by cumulative dry biomass or energy in the unit area or unit time with the unit of g/m^2 or t/hm^2. The particle took RM data from landsat 5 TM as an example and used Tahe forest bureau as the research area. Based on the permanent plot, the main biomass model for the 7 tree species was developed and tried to construct multi - level linear regression model to estimate biomass in large region by employing the relationship between TM image and plots.
