The forest carbon storage estimation methods based on the forest inventory data(FID) are important in assessing forest carbon budget in terms of landscape

regional

and national scales

and play an important role in studying terrestrial ecosystem carbon cycle and global changes.The vegetation carbon storage in forest ecological system is usually calculated by multiplying forest biomass of the forest ecological system with its biomass carbon content

and in the world

the coefficient commonly is 0.45~0.55.There are basically four methods for forest biomass estimation based on FID: IPCC method

a constant BEF of biomass expansion factor method

biomass expansion factor continuous function method and biomass experience(regression) model method.The quantitative methods of forest carbon storage estimation based on FID of forest vegetation were reviewed.The problems related to the methods were pointed out

and improvement proposals were put forwards for future forest carbon storage estimation methods.In forest carbon storage estimation

remote sensing techniques need to be stressed

the carbon flux in the forest inventory need to be increasingly employed and the inversion models fitted to the actual situation in China need to be developed in the future.
