摘  要:
By the methods of sampling plot harvesting method and allometric dimension analysis,we measured the belowground and aboveground standing biomass and net primary productivity(NPP) of the secondary evergreen broadleaved forest in Huangmian Forest farm of Guangxi,southern China,with the location of 24°51′N and 109°51′E and an altitude of about 315 m.The total biomass was 99.96 t·hm -2 ,aboveground and belowground biomasses accounted for 69.41% and 30.59%,respectively.The leaf area index of trees and undergrowth shrubs was 6.50,and the total annual NPP was 24.65 t·hm -2 ·yr -1 by estimate,aboveground and belowground NPP accounted for 44.54% and 55.46%,respectively.The NPP of fine roots was 11.79 t·hm -2 ·yr -1 ,being 86.24% of the belowground NPP.
