摘要
第九次全国森林资源清查结果,广西桉树人工林面积达到256.05万hm^(2),其中幼龄林面积最大,比例占到45.23%。桉树人工林蓄积量10989.47万m^(3),其中中龄林蓄积量最大,比例占到50.48%。本文利用相关计算公式根据森林资源清查结果得出广西桉树人工林固碳总量为3260.11万t,平均固碳效率为12.73 t·hm^(-2);释放氧气总共为7759.06万t,生态效益十分可观。
According to the results of the Ninth National Forest Inventory,the area of Eucalyptus Plantations in Guangxi has reached 2.560 million hm^(2),of which the area of young forest is the largest accounting for 45.23%.The total standing volume of these Guangxi Eucalyptus plantations is 109.895 million m^(3),of which the volume of middle-aged plantations is the largest,accounting for 50.48%.According to the results of forest resources inventory,the total carbon sequestration of Eucalyptus plantations in Guangxi is 32.601 million t,the average carbon sequestration efficiency is 12.73 t·hm^(-2),and the total oxygen release is 77.591 million tons,which has considerable ecological benefits.
