The model method was used to study the carbon storage and carbon sink changes of forest resources in Shanxi Province with 7 forest resource inventory data from 1984 to 2015 as the object.The results showed that from 1984 to 2015,the forest coverage rate in Shanxi Province increased by 14.20%and the forest volume increased by 9 172.88 × 104 m3.The fitting curve of forest coverage was linear,and the fitting equation was y=0.453 x-892.820.The fitting curve of for-est volume was a binomial distribution,and the fitting equation was y=0.000 9x2-3.487 5x+3 459.6000.The unit area storage volume of forest resources in Shanxi Province was 30.05 m3/hm2~40.25 m3/hm2,which was much lower than the national average level and had significant growth potential.The carbon storage of forest resources was 4 343.79 x 104 t~14 970.80 × 104 t.The carbon density was 14.28 t/hm2~19.12 t/hm2,and the carbon sink was 128.82 × 104 t/a~737.56 × 104 t/a.The fitting curve of forest resource carbon storage was a binomial distribution,and the fitting equation was y=0.001x2-4.040x+4 008.000.
