森林生物量的估算方法及其研究进展

Forest Biomass Estimation Methods and Their Prospects

总结分析生物量模型(包括相对生长关系和生物量-蓄积量模型)和生物量估算参数这2类常用的生物量估算方法,提出今后我国在森林生物量估算领域的研究重点:1)整合经验相对生长方程;2)系统研究生物量估算参数的规律性及其不确定性;3)构建以传统估算方法和3S技术相结合的生物量估算系统。

Two widely accepted methods for forest biomass estimation （i. e. biomass function and biomass factors） were summarized and analyzed, where biomass function includes biomass allometric equation and biomass-volume model. Based on these analyses, the prospect in forest biomass estimation in China was proposed： 1） collection and comprehensive studies of empirical biomass allometric equations; 2） definitions, rules and uncertainties of estimation of biomass factors; 3） development of a biomass estimation system that integrates the frequently used methods and 3S technologies.
