| Abstract: | The forest ecosystem is the largest terrestrial carbon pool which plays an irreplaceable role in mitigating the global climate warming.Estimation of forest biomass can provide a basis for assessing the contribution of forest ecosystem to global carbon cycle.The status of single-tree biomass modeling abroad was reviewed in this paper.The key technical aspects on single-tree biomass modeling,including sample data collection,modeling procedure,model evaluation,and model application,were summarized systematically.In addition,considering the needs of conducting national forest biomass monitoring,the general single-tree biomass modeling was suggested to be the study emphases. |
