摘要: Aegiceras corniculatum grows as single-stemmed evergreen shrub or small tree in the Sundarbans mangrove forest of Bangladesh. The objectives of this study were to derive allometric models for estimating above-ground biomass, nutrients (N, P and K) carbon stock A. corniclatum. A total of 8 linear (y = aX + b, , y aLogX Logy = Logy alnX Lny b b) with 64 regression equations tested model biomass of each plant part; total aboveground biomass. best fit selected by considering values of R2, CV, Rmse, MSerror, Sa, Sb, F value, AICc Furnival Index. were Logbiomass 0.76LogDBH2 - 1.39; Biomass 0.07DBH2 - 0.49; Logbiomass 1.04LogDBH2 1.80; 0.99; 0.48DBH 0.13 leaves, branches, bark, stem without bark total above-ground biomass respectively. Nitrogen, Phosphorous, Potassium Carbon above-ground 0.67DBH 0.11; 0.94DBH 0.08; 1.06DBH 0.18; 0.33DBH 0.09
