The Brazilian Ministry of Science and Technology (MCT) / National Council for Science and Technological Development (CNPq) financed the research project "Identification and Quantification of the Main Chemical Components of Mimosa scabrella Benthan, related to Forest Management Parameters". One of the objectives of the study was to determine the dynamics and structure of carbon fixation in reforestation, quantitatively and qualitatively. It examined permanent carbon storage in living trees using conventional reforestation practices aimed at producing diverse traditional products. The carbon density decreased with the diameter class of the stands : the carbon density in non-dominant trees was 310 kg/㎥, while it was 280 kg/㎥ in dominant trees. The production function for carbon assimilation C (ton/ha) was given by the model : C=I^2/(0.154397-0.011314×I+0.026268×I^2),where I is stand age (years). This permitted calculation of the productive structure. For continuous production, in the optimized regime, the forest in 30 rural farms should be divided into four age classes, each with the same area of production (167.84 ha) ; this would maintain a permanent stock of 13, 131 tons of carbon in the living population of Mimosa scabrella.農林水産研究情報センターで作成したPDFファイルを使用している。
