吉林西部森林植被碳汇功能的研究

Study on carbon sink of forest cover in west Jilin Province

以吉林省西部地区2010年森林资源面积、蓄积量及生长量、消耗量为基础数据,按IPCC清单法测算了该区域森林植被生物量、碳储量和年固碳量。结果表明:吉林西部森林植被生物量为3 015.91万t,单位面积生物量为55.65 t.hm-2;森林植被碳储量为1 494.67万t,森林植被碳密度为27.58 t.hm-2,森林植被年固碳量为26.89万t.a-1。

According to the inventory method from IPCC,the biomass,carbon storage and annual carbon fixation of forest cover were calculated,based on the data of forest area,stock volume,growth rate and specific consumption in west Jilin Province.The results indicated that： the biomass was 3 015.91×10^4 t,biomass per unit area was 55.65 t·hm^-2,carbon storage was 1 494.67×104 t,carbon intensity was 27.58 t·hm^-2,and annual carbon fixation was 26.89 ×10^4 t·a^-1.
