摘　　要：科学估算湖北省森林植被的碳储量和碳密度,可为研究区域尺度的森林碳汇和碳潜力提供科学依据。本研究以湖北第五次森林资源普查数据为基础,采用生物量转换因子方法,结合不同树种含碳率,分析湖北省乔木林地不同地类、优势树种和龄组的碳储量分布特征。结果表明:湖北省森林植被层平均碳密度为32.51 Mg C/hm 2,碳储量总量为2.62×108 t,不同地类碳密度大小排序为乔木林>竹林>疏林地>灌木林。天然林碳密度和碳储量均明显高于人工林。随林龄的增加,森林碳储量逐渐升高,中幼龄林碳储量占全省森林碳储量总量的83.59%。湖北省森林植被层碳储量主要集中分布于鄂西北、鄂西南、鄂东等山区,优先提升该区域的森林质量,将有利于全省森林植被碳密度和碳储量水平的快速提升。Scientific estimation of carbon storage and carbon density of forest vegetation in Hubei Province,which can provide scientific basis for studying forest carbon sink and carbon potential at regional scale.Based on the data of the fifth forest resource census in Hubei Province,the biomass conversion factor method and carbon content of different tree species were used to analyze the carbon storage distribution characteristics of different land classes,dominant tree species and age groups in the arbor forest in Hubei Province.The results showed that the average carbon density of forest vegetation layer in Hubei Province was 32.51 Mg C/hm 2,the total carbon storage was 2.62×108 t,and the carbon density of different land types was ranked as tree forest>bamboo forest>woodland>shrub forest.The carbon density and carbon storage of natural forest were significantly higher than that of plantation forest.With the increase of forest age,the forest carbon storage gradually increased,and the carbon storage of middle-aged and young forests accounted for 83.59%of the total forest carbon storage in the province.The forest vegetation carbon storage in Hubei Province is mainly distributed in the mountainous areas of northwest Hubei,southwest Hubei and east Hubei,the priority to improve the forest quality in this region will be conducive to the rapid improvement of the carbon density and carbon storage level of forest vegetation.
