Zhao Ti · He'nan nongye daxue xuebao · 1999
Based on the 35 plots and 35 analytic trees, this paper deals with the biomass and productivity of Larix kaempferi. The results showed that the biomass increases in pace with the accretion of ages, density and dominant height. In the same age period, influence of dominant height upon biomass is greafer than that of density. The biomass of 23 ages Larix kaempferi is 249.43 t·hm -2 . Net productivity is 16.83 t·hm -2 ·a -1 . The biomass is estimated by means of W=a(D 2H) b . The correlation coefficient comes up to significant level.
