ABOVE-GROUND BIOMASS AND CARBON STOCKS ESTIMATION USING ALLOMETRIC EQUATIONS IN TROPICAL FOREST

摘要

Tropical forests contribute to the extensive amount of above-ground biomass (AGB) and carbon stocks for the whole world. Over the past few centuries, the concentration of carbon dioxide (CO:) including greenhouse gases to the atmosphere has become increased due to anthropogenic activities and natural consequences, which has an enormous influence on the impact of climate change. Therefore, forests play an important role in human life in supplying oxygen (O_2) and absorbing carbon dioxide (CO_2) to stabilize the earth's ecosystem. In protecting forests that have a variety of trees, many researchers have developed a variety of methods and ways to estimate the above-ground biomass and carbon stock. In general. AGB was an estimate based on the structure and volume of the trees, which is the trees height and diameter at breast height (DBH) consider as major parameters. In the absence of species-specific biomass equation of the tree, many equations will be used to estimate for individual tree species in tropical forest type which had been developed by world global researchers. The aim of this study was to measure the estimation of AGB and carbon stock using regression model. Hence, the objective of this study: 1 to estimate AGB and carbon stock in a tropical forest using allometric equation, and 2 to investigate the relationship between Diameter at Breast Height (DBH) with AGB and carbon stock estimation. Based on the result, there was a relationship between DBH with AGB and carbon stock estimation by using different equation.
