Abstract: Seedlings of five broad leaved tree species including Castanopsis lamontii , Cyclobalanopsis myrsinaefalia ,Castanopsis fissa ,Castanopsis kawakmii and Castanopsis sclerophylla were separately interplanted in mature Pinus massoniana plantation to form uneven-age mixed stands .The analysis of data on the biomass showed that arbor biomasses in the five communities were 259.882 , 221.745 , 221.652 , 245.941 and 200.875 t hm-2 respectively .The biomass in the pure Pinus massoniana stand was 172.90 thm-2 .Trunk biomass was the highest in the arbor biomass and root , branch and leaf came to the next .In the mixed forests , thick roots of Pinus massoniana were mainly distributed in the 0 -20 cm layer and the layer under 60 cm , and fine roots of broad leaved trees and Pinus massoniana were distributed in the 0 -20 cm layer .Vegetation biomass in Pinus massoniana stand was 3.678 t hm-2 , the highest among the six communities .The vegetation biomasses in the five mixted communities were 0.937 , 1.816 , 1.625 , 0.987 and 0.801 t hm-2 respectively .Except for the mixed community of Pinus massoniana and Castanopsis lamontii , biomasses of vegetation in other communities were concentrated in the parts above ground .[ Ch , 2 fig .2 tab .11 ref .]
