Studies on the biomass and productivity of Tsoongiodenron odorum plantation
摘要
Abstract
This study was to explore the biomass and the productivity of a 27 year old Tsoongiodenron odorum plantation, analyze the biomass distribution of the different diameter grades, stand biomass and the productivity, and establish estimation models between D2H and biomass of different organs according to the correlations among different organs. The results showed that biomass of Tsoongiodenron odorum increased along with the increasing of diameter grades. The accuracy of the biomass estimating model established by the D2H of different diameter grades was high. The model could be used to estimate the biomass in the actual production, the stand biomass of Tsoongiodenron odorum plantation was 102.57 t/hm2. A-mong them, the biomass of tree layer accounted for 87.07% , the biomass of shrub layer, herb layer and humus layer was 8.61 t / hm2, 1. 83 t / hm2and 2.82 t/ hm2 respectively. The productivity of Tsoongiodenron odorum plantation was 7.4 t / hm2, indicating a relatively high net productivity.关键词
