摘要
从单传感器和多传感器遥感数据集成两个方面介绍和阐述了遥感技术估算森林生物量的发展现状,以此提炼遥感技术估算森林生物量研究面临的问题。
To further confirm the role that forest ecological system plays on global warming and global carbon cycle, quantitative study on forest biomass of large scale areas is needed. Traditional approaches based on field measurement are highly accurate, while they are only fit for small place and difficult to implement in large place. With the breakthrough progress in quantitatively obtaining forest parameters such as height of forest, canopy density, etc. , remote sensing has become the primary source for biomass estimation. We review research progress of remote sensing-based biomass estimation from single- and multi-sensor data, and discuss existing issues influencing biomass estimation.
