| Biomass is the measure of forest ecological system function of the number of the most basic characteristics, biomass based data has become a measure forest structure and function change is the important index of the ecological system for the carbon and carbon cycle research provide key data in carbon cycle, global climate change study play an important role. This study on Cyclobalanopsis glauca plantation of biomass and productivity were determined, understanding of forest age and tree height, DBH, and volume, the correlation between them, to master the tree species in this area growth dynamics, to make effective management measures to improve the quality and quantity of forest resources has important practical significance.This paper adopt standard sample plot survey method, by using trunk analytic method, the quadrat harvest method, the method of layered harvest in guangxi d all 1980 forest reforestation Cyclobalanopsis glauca plantation biomass, productivity and growth rule was research. The results of the study showed that:1, Cyclobalanopsis glauca tree height, DBH and volume total increment growth rule are basically the same, all increases with age, and when a three increment were 18.1 m,33.21 cm and 0.54035 m3. Tree height growth in maximum （0.90 m） appeared in the afforestation after a 6, the highest average increment appeared in afforestation after a 9. Years of DBH growth overall present a first growth falling growth trend, the highest average increment for 6 a 2.02 cm. The volume growth in successive years with tree age of increasing first growth decline, in successive years increment peak for a 220.03585m3, volume number for a mature age of 32.2, Cyclobalanopsis glauca growth rule regression equation fitting, tree height, DBH and forest age regression model with Richard model optimal, volume to Sumake model for optimal, fitting correlation coefficient R2 were all above 0.997, the sum of squared residuals is lesser, growth prediction model has higher accuracy, and can be applied to production practice.3,32 year old Cyclobalanopsis glauca plantation monoclonal total biomass as high as 935.87 kg · strains-1,of which the ground part is 757.17 kg, underground part is 178.70 kg, respectively accounted for 80.91% and 19.09% of the total biomass. Each organ biomass the largest is the trunk （426.40 kg）, and the youngest is fine root （2.75 kg）, accounted for 45.56% of the total biomass per and 0.29%, the whole plant each organ biomass size order:trunk> great branches> root hill> bark> branchlets> leaf> coarse root> deadwood>> root of fine roots.4, Cyclobalanopsis glauca plantation forest stand total biomass for 600.601 · hm-2, tree layer of total biomass for 592.411 · hm -2, accounting for 98.64% of the total forest biomass, tree layer aboveground part and underground part were 479.29t·hm-2 and 113.121 · hm-2, the ground part of the biomass accounted for the total biomass of the tree layer and the stand total biomass of 80.90% and 79.80%, respectively underground part of tree layer always stand biomass and total biomass of 19.10% and 18.83%; Forest biomass in vertical direction in the order of the size of the tree layer> litter layer> shrub layer> herb layer, the distribution of forest biomass present ground cover （litter layer） than live ground cover, shrub layer and herb layer) distribution pattern.5,32 years raw Cyclobalanopsis glauca stand productivity for 23.10t · hm-2per year, in Joe, irrigation and herb three vegetation layer productivity size distribution for tree layer (22.25 t · hm-2)> shrub layer (1.261 · hm-2)> herb layer (0.441 · hm -2), respectively in the forest stand total productivity of 96.31%,5.46% and 1.92%.6.32a of Cyclobalanopsis glauca Artificial forest carbon storage for 411.83 t-hm"2, the layer of vegetation carbon storage 283.78 t·hm-2, soil carbon storage for 128.05 t·hm-2. Cyclobalanopsis glauca tree layer in various organs of the carbon storage in proportion to the size of the order:trunk> Branch> root> bark> leaf> root diameter> root>small root. Cyclobalanopsis glauca Artificial Forest shrub layer carbon storage:3.80 t·hm-2 Cyclobalanopsis glauca Artificial Forest and grass layer carbon storage:0.38t·hm-2, and the Cyclobalanopsis glauca Artificial forest litter layer carbon storage quantity is 2.29 t·hm-2.7,32 year old Cyclobalanopsis glauca plantation ecological system provided by the ecological service value totaled 220800 · hm-2 per year, including single ecological service value size sequence is as follows:the soil and water conservation value> fixing carbon and releasing oxygen value> water conservation value> purify air value, single ecological service value of the soil and water conservation value, fixing carbon and releasing oxygen value, water conservation value and purify air value value respectively for 104200 · hm-2 per year,65400 · hm-2 per year,45500 · hm-2 per year and 5700 · hm-2 per year. |
