Review of Forest Biomass Estimation Methods

As the main component of terrestrial ecosystem, forest ecosystem has strong carbon sequestration ability. Forest biomass is an important index to evaluate forest carbon storage capacity and its estimation method has been a hot topic in ecological research. This paper introduces several classical methods of biomass estimation, including direct observation and indirect estimation. And it summarizes their research trends and shortcomings. It also points out the direction of improvement and perfection in the future. In the context of global warming, it is significant to understand and master the research trend of forest biomass estimation methods. People should face up
