摘要
利用遥感技术估算森林生物量是快速准确地获取森林生态系统生物量信息的重要途径。森林生物量的遥感估测精度受遥感数据、自变量选择及模型建立方法等多种因素的影响。其中遥感数据和自变量选择是影响遥感技术森林生物量估算的主要因素。分析了2个主要因子的特点及当前解决方法,并简要总结了遥感技术在森林生物量估算应用方面的发展趋势。
Remote sensing technology provide a very quick way to improve the accuracy of the estimation of forest biomass.Yet there are many factors affecting this process such as remote sensing data,the selection of independent variables and model methods.Among these factors,remote sensing date and independent variable selection are regarded as the factors having more impacts.This paper discussed the two factors and corresponding solutions to them.At the same time,this paper also briefly analyzed the trend of estimation of forest biomass by remote sensing.
