摘要
森林生物量是森林碳汇能力的重要标志之一,同时也是众多林业问题和生态问题的研究基础。估测生物量的方法可分为传统地面实测法、基于遥感经验模型的生物量估测法以及基于遥感机理模型的生物量估测法。对3种不同方法进行比较分析,结合研究现状,探讨森林生物量估测的发展趋势。
One of the important signs of forest carbon sink ability is forest biomass,which is also the research basis of numerous forestry and ecological problems. There are three methods for estimating biomass,the traditional above- ground biomass estimation method,the remote sensing experience model based biomass estimation method and the remote sensing mechanism model based biomass estimation method. After comparing and analyzing of the three different kinds of methods and combining the current state of research,the development trend of forest biomass estimation was discussed.
