PetroChemical Research Institute of PetroChina, Beijing 100195, China） Abstract: Forest ecosystem, as the main body of the Earths terrestrial biosphere and the largest terrestrial carbon pool, plays an important role in fixing atmospheric CO2 and mitigating climate change. This paper summarized three main estimation methods of forest sequestration: inventories, eddy covariance and application of remote sensing modeling, with their advantages and shortages and the computational method which with the forest biomass, carbon reserves and carbon density. The internal relations that the comprehensive application of several methods should be further studied to consummate a long-term continuous observation system and regional monitoring network construction. These studies will improve estimation accuracy and provide reasonable parameters. Keywords: forests, carbon storage, estimation methods 碳是地球外壳生态系统中分布最广泛的元素之一，它以各种形式存在于海
