摘      要：Allometric equations are important for quantifying biomass and carbon storage in terrestrial forest ***,equations for dry deciduous woodland ecosystems,an important carbon sink in the lowland areas of Ethiopia have not as yet been *** study attempts to develop and evaluate species-specific allometric equations for predicting aboveground biomass(AGB)of dominant woody species based on data from destructive sampling for Combretum collinum,Combretum molle,Combretum harotomannianum,Terminalia laxiflora and *** at breast height ranged from 5 to 30 *** empirical equations were developed using DBH(Eq.1)and height(Eq.2).Equation 2 gave better AGB estimations than *** inclusion of both DBH and H were the best estimate biometric variables for ***,the equations were evaluated and compared with common generic allometric *** result showed that our allometric equations are appropriate for estimating *** development and application of empirical species-specific allometric equations is crucial to improve biomass and carbon stock estimation for dry woodland ecosystems.
