摘要
以1984年至2015年7次森林资源清查数据为对象,采用模型法研究山西省森林资源碳储量及碳汇量变化情况.结果表明,从1984年至2015年,山西省森林覆盖率净增长14.20％,森林蓄积量净增长9 172.88 ×104 m3.森林覆盖率拟合曲线呈线性,拟合方程为y=0.453 x-892.820;森林蓄积量拟合曲线呈二项式分布,拟合方程为y=0.000 9x2-3.487 5x+3 459.600 0.山西省森林资源单位面积蓄积量为30.05 m3/hm2～40.25 m3/hm2,远低于全国平均水平,有较大增长空间;森林资源碳储量为4 343.79 × 104 t～14 970.80 × 104 t,碳密度为14.28 t/hm2～19.12 t/hm2,碳汇量为128.82 ×104 t/a～737.56 × 104 t/a.森林资源碳储量拟合曲线呈二项式分布,拟合方程为y=0.001x2-4.040x+4 008.000.
Abstract
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.
