摘要
探讨了用在ＴＭ数据中与地面对应的样点上测得的密度值和波段比，并加上定性因子与地面样地中分别测得的蓄积量进行多元回归，从而估测森林二类调查中所需的林业局、场、林班之蓄积量的方法。并与实测结果进行了对比，证明这一方法是可行的。为遥感在二类调查中的应用提供了必要依据。
A multi-regression equation was established by using density value, band ra-tid of
sample points on TM image,which were corresponding to the field sample plots,3 qual-itative
factors and the stock value measured from the field sample plots.This equation can beused to
estimate the stock values of forestry bureaus,forest farms,or forest compartments inforest
management inventory.Finally,the data obtained from the remote sensing estimationwas
compared with that obtained from the field inventory.It proved that this method is ef-fective.It
provides scientific basis for remote sensing application in forest management
in-ventory.
