摘要
提出了一种利用遥感数据、气象数据、地形数据以及森林调查数据反演森林生物量和碳储量的新方法,以尺度生长理论为基础,利用环境和地形因子、森林资源调查样地数据等资料,估算了三峡库区森林树高、树高与胸径之间的尺度关系、以及森林胸径分布图,并在此基础上,利用生物量样地数据建立了胸径和生物量之间的尺度关系方程,反演得到2008年研究区的生物量为1.34×108t和碳储量为6.37×108t。
An inversion method of forest biomass estimation and carbon was proposed in this paper.Remote sensing data,climate data,topographic data and field measured data were used in this research based on allometric scale theory to estimate forest heights,the scale relation between forest heights and diameter,and the diameter at breast height.Finally,allometrica scale function was built,and the forest biomass and carbon in 2008were separately estimated as 1.34×108t and 6.37×108t.
