Based on the result of study on aboveground biomass of Pinus massoniana Lamb at dashan zongyang and yansi huangshan indicated:based on relative growth-style W=a(D~2H)~b and data of DBH,tree height,biomass of all organs of standard wood, established the biomass regression equation of all aboveground organs of Pinus massoniana Lamb at dashan zongyang and yansi huangshan.Biomass model have high correlation coefficient at two sites,the lowest was 0.9169,most of them were hyper-0.99,it can be used to calculate the aboveground biomass of Pinus massoniana Lamb.The proportion of biomass of trunk without bark in total biomass of Pinus massoniana Lamb at dashan zongyang were respectively,26%for 7a,34.6%for 10a, 53.7%for 14a,52.2%for 19a,58%for 23a.The proportion of biomass of trunk without bark in total biomass of Pinus massoniana Lamb at yansi huangshan were respectively, 51.2%for 4a,27.5%for 7a,48.5%for 11a,63%for 17a,58%for 22a.The proportion of biomass of bark in total biomass of Pinus massoniana Lamb at dashan zongyang were respectively,2.7%for 7a,3.3%for 10a,4.1%for 14a,3.3%for 19a, 3.3%for 23a.The proportion of biomass of bark in total biomass of Pinus massoniana Lamb at yansi huangshan were respectively,7.8%for 4a,3.6%for 7a,4.8%for 11a,3.8% for 17a,4%for 22a.The proportion of biomass of branch without bark in total biomass of Pinus massoniana Lamb at dashan zongyang were respectively,33.9%for 7a,29.8%for 10a, 20.1%for 14a,33.2%for 19a,23.5%for 23a.The proportion of biomass of branch without bark in total biomass of Pinus massoniana Lamb at yansi huangshan were respectively, 24.3%for 4a,43.9%for 7a,32.3%for 11a,21.4%for 17a,23.3%for 22a.The proportion of biomass of bark of branch in total biomass of Pinus massoniana Lamb at dashan zongyang were respectively,4%for 7a,3.2%for 10a,1.7%for 14a,2.1% for 19a,1.4%for 23a.The proportion of biomass of bark of branch in total biomass of Pinus massoniana Lamb at yansi huangshan were respectively,3%for 4a,4.9%for 7a, 2.7%for 11a,1.5%for 17a,1.9%for 22a.The proportion of biomass of pine needle in total biomass of Pinus massoniana Lamb at dashan zongyang were respectively,33.4%for 7a,29.1%for 10a,20.5%for 14a,9.8% for 19a,13.7%for 23a.The proportion of biomass of pine needle in total biomass of Pinus massoniana Lamb at yansi huangshan were respectively,13.7%for 4a,20.3%for 7a, 11.9%for 11a,10.1%for 17a,12.7%for 22a.Vertical distribution of biomass of all aboveground organs of Pinus massoniana Lamb at dashan zongyang were respectively:biomass of trunk without bark distributed mainly under 6m,biomass of bark also distributed mainly under 6m,biomass of branch without bark distributed in 4-8m,biomass of bark of branch also distributed in 4-8m,biomass of pine needle distributed hyper-6m.Vertical distribution of biomass of all aboveground organs of Pinus massoniana Lamb at yansi huangshan were respectively:biomass of trunk without bark distributed mainly under 8m,biomass of bark also distributed mainly under 8m,biomass of branch without bark distributed in 5-9m,biomass of bark of branch also distributed in 5-9m,biomass of pine needle distributed hyper-7m.
