摘　　要：利用森林资源监测数据,运用换算因子连续函数法对额尔古纳市优势树种进行生物量和碳储量的估算,分析不同龄组的碳储量,并推算出优势树种的碳储量价值。结果表明:额尔古纳市优势树种的生物量为49945.94×10^(3) t,碳储量为22475.63×10^(3) t,碳储量价值为191087.81万元。不同的优势树种碳储量有较大差异,白桦占7个优势树种总碳储量的91.71%。不同龄组的碳储量由高到低为:中龄林>近熟林>幼龄林>成熟林>过熟林,中龄林和近熟林有较大的碳储能力。额尔古纳市森林碳储量潜力较大,要继续提高林分质量,扩大森林蓄积量,挖掘森林潜在碳汇能力。Using forest resource monitoring data,the biomass and carbon storage of dominant tree species in Erguna City were estimated using the conversion factor continuous function method.The carbon storage of different age groups was analyzed,and the carbon storage value of dominant tree species was calculated.The results showed that the biomass of dominant tree species in Erguna City was 49945.94×10^(3) t,with a carbon storage of 22475.63×10^(3) t and a carbon storage value of 1910878100 yuan.There are significant differences in carbon storage among different dominant tree species,with white birch accounting for 91.71% of the total carbon storage among the seven dominant tree species.The carbon storage capacity of different age groups from high to low is as follows:middle-aged forest>near mature forest>young forest>mature forest>over mature forest,with middle-aged and near mature forests having greater carbon storage capacity.This indicates that there is great potential for forest carbon storage in Erguna City,and efforts should be made to continue improving forest quality,expanding forest stock,and tapping into the potential carbon sink capacity of forests.
