Abstract

To increase future forest research efficiency and management,a model of branch biomass and growth increment for mid-young-aged Pinus elliottii was determined. Estimates were made using the branch analysis method with regression models of crown biomass and increment-established. Results showed a significant power correlation existed between branch biomass(WB) and branch diameter(DB) (WB=0.017 8 DB3.006 1) with r2=0.840 8(PATB) and diameter at breast height(DBH) was well fitted by ATB=1.850 2 DBH1.541 8 with r2=0.750 9(PWC) and DBH(WC=7.105 9 DBH2.596 5) with r2=0.920 5(Py) and DBH increment(x) was also well fitted by y=29.354 1x0.255 4 with r2=0.956 6(P<0.01).
