通过调查七坡林场的森林资源家底,科学评估林场森林碳储量和价值量.将七坡林场 2015年与2020 年资源现状进行对比,采用森林资源蓄积量扩展法,核算森林碳储量,分类统计碳汇价值变化.结果表明,5 年间,七坡林场森林面积增长 78.1 hm2,森林蓄积量增加 174 954 m3,森林碳储量增加202 688.58 t;森林碳储量从2015 年的1 047 184.95 t增加到2020 年的1249873.54 t,增加202 688.58 t,增长率为 19%;混交林面积从 2015 年的 130.0 hm2 增加到 2020 年的 1 218.9 hm2,2020 年碳储量198885.15 t,较2015 年增长近13 倍.由此可见,七坡林场2015-2020 年期间林场坚持在分区施策、分类经营和可持续发展原则的基础上,有计划、有步骤地开展森林经营管理活动,加强森林资源保护与建设,在森林碳储量和碳汇价值提升上取得显著成效.以期为七坡林场科学改进森林资源保护、经营和利用措施提供数据支撑,对评估区域森林生态系统碳汇能力、评价森林碳汇价值提供借鉴.
Value Assessment of Forest Carbon Sequestration in Qipo Forest Farm
This paper analyzed the forest resources in Qipo Forest Farm,scientifically evaluated the forest carbon stock and value.By comparing the current resource status in 2015 with that in 2020,the method of expanding forest resource stock to calculate forest carbon stock and classify the changes in carbon sink value.The results showed that during the five years,the forest area of Qipo Forest Farm increased by 78.1 hm2,the forest stock increased by 174954 m3,and the forest carbon stock increased by 202688.58 t.The forest carbon stock increased from 1 047 184.95 t in 2015 to 1 249873.54 t in 2020,increasing by 202688.58 t,with a growth rate of 19%.The area of mixed forest increased from 130.0 hm2 in 2015 to 1 218.9 hm2 in 2020,and the carbon stock was 198 885.15 t,with an increase of nearly 13 time com-pared to 2015.From 2015 to 2020,Qipo Forest Farm insisted on carrying out forest management activi-ties in a planned and step-by-step manner on the basis of the principles of zoning policy,classified man-agement and sustainable development to strengthen the protection and construction of forest resources,a-chieving remarkable results in the enhancement of forest carbon stock and carbon sink value.The results aimed to provide data support for the scientific improvement of forest resource protection,management,and utilization measures in Qipo Forest Farm,and to provide reference for evaluating the carbon sink ca-pacity and value of regional forest ecosystems.
