Biomass Structure Comparison on Moso Bamboo Mixed Forest Communities

Four different management mode Moso Bamboo stands are selected from Datian Township,Taining County,Fujian Province,i.e.,Mode A,Moso Bamboo and broadleaf tree mixed forest(crown projection ratio of 5:5);Mode B,Moso Bamboo and broadleaf tree mixed forest(crown projection ratio of 8:2);Mode C,Moso Bamboo pure forest;Mode D,Moso Bamboo and China fir mixed forest.Through analysis and comparison to different mode Moso Bamboo stand biomass structure,the results show that:the differences are outstanding between such growing factors as Moso Bamboo DBH C diameter at breast height) and bamboo height,etc.of different mode stand,and the Moso Bamboo mean individual biomass,DBH and bamboo height value in broad leaf mixed forest are relatively high;the individual organ biomass of Moso Bamboo takes bamboo stem,s percentage as the biggest one,up to 46.81 %~54.27 %,among them,Mode B is the highest one;for the individual gross biomass of Moso Bamboo,the highest one is Mode A,up to 34.98 kg/tree;for community gross biomass of Moso Bamboo,the highest one is Mode D,i.e.,bamboo and China fir mixed forest,up to 139.42 t/hm2.
