Comparison of alternative approaches of estimating above-ground tree biomass in a forest ecosystem of Turkey

摘要

This paper discusses different above-ground biomass estimation approaches in a forest ecosystem consisting of one tree species in Turkey. The first and second approaches are based on the use of growing stock volumes converted to above-ground biomass using forest type-level and species-specific biomass factors, respectively. The third and fourth approaches use different species-specific biomass regression equations. These equations used for estimating above-ground biomass are based on diameter at breast height in the first one, tree height as well as diameter at breast height in the second one. Results of above-ground biomass estimation approaches showed that more total above-ground biomass estimated in biomass expansion factors than that in biomass regression equations. It is concluded that species-specific biomass regression equations that are more practical, accurate and useful should be developed.
