Abstract: This study analyzed characteristics of biomass and productivity in Larix gmelinii natural forests with different stand structures,and established models for the total biomass and the biomass of trunks,branches and leaves. Results show that:i) As to the productivity,total biomass and biomass proportion of branches and leaves,the grasses + larch forest is higher than the Ledum palustre + larch forest,while for the ratio of the biomass of trunks in the total biomass,the latter is higher than the former. With a density of 1 000 - 3 000 plantshm-2,the highest biomass and productivity of grasses-larch forest and Ledum palustre + larch forest are respectively 55.82 thm-2,0.99 thm-2a-1 and 50.36 thm-2,0.83 thm-2a-1. The lowest biomass proportion of trunks,branches and leaves in the grasses + larch forest is respectively 79.6%,14.6%,and 4.8%;and 83.4%,8.8%,and 3.6% in the Ledum palustre + larch forest. ii) Along with the increase of density,the productivity,total biomass of the grasses + larch forest as well as its biomass proportion of branches and leaves increase,whereas the biomass of branches decreases. iii) As the quota of larch forest increases in the species composition,the productivity,total biomass and the biomass proportion of trunks of forest stand are tending to increase,whereas the biomass proportion of branches and leaves decreases.[Ch,5 tab. 19 ref.]
