Estimation of aboveground biomass of different mangrove trees based on canopy diameter and tree height

Determination of aboveground biomass (AGB) is an important step in planning the protection and sustainable use of mangrove resources. In the present paper, allometric relationships for estimating AGB of different morphology mangrove trees on the basis of canopy diameter (CD) and tree height (H) were studied. By comparing of correlation between AGB and CD2*H, and of relative error rates between measurement value and simulation value within the three mangrove specie, results show that regression equation, in the form of AGB=a(CD2*H)b, is very suitable for estimation of AGB of multi-stemmed mangrove trees such as Aegiceras corniculatum, and is not suitable for single- stemmed mangrove trees such as Kandelia candel, but may be applied to those mangrove trees between multi- stemmed and single-stemmed in morphology such as Avicennia marina.
