摘要
利用植物光合作用原理及群落生物量、林地面积等基本监测数据,对黑龙江省东折棱河林场长白落叶松人工林固碳释氧能力及其经济价值进行了初步估算,并分析了不同林龄结构的碳密度和年固碳能力。结果表明:不同林龄长白落叶松人工林的碳储存能力大小依次为:中龄林>近熟林>成熟林>幼龄林>未成林,平均碳密度为91.672 t.hm-2,总碳储量为40659.627 t,年固碳量为3.223t.hm-2,CO2和释放O2的经济价值分别为3893.1729万元和3636.918 3万元。
A study was conducted to assess the carbon sequestration and oxygen release of Lar/x olgensis plantations and its ecological service values by the investigation of the biomass and area of L. olgensis plantations of different ages at Dongzhelenghe Forest Farm, according to the principle of plant photosynthesis. The carbon density and annual carbon sequestration capacity of different forest age structures were analyzed. Results showed that the carbon sequestration capacity of the middleaged forest was the highest, followed by near-mature forest, mature forest, young forest, and unwoodland. The mean carbon density was 91. 672 t ·hm^-2 the carbon storage 40 659. 627 t, annual carbon sequestration 3. 223 t·hm^-2, and the economic values ror carbon sequestration and oxygen release were 38 931. 729 and 36 369. t83 thousand yuan respectively.
