龙山林场森林碳储量及碳密度研究

Carbon Storage and Carbon Density in Longshan Forest Farm

通过对龙山林场人工林及天然林的碳储量及碳密度进行计量研究,结果表明10种林分类型固定二氧化碳总量为113.08万t,其中红松林为57 085.86t,落叶松林为94 395.86t、樟子松林为77 493.36t、云杉林为540.8t、柞树林为838 309.87t、白桦林为3 306.04t、山杨林为1 890.56t、椴树林为2 102.03t、软阔混交林为3 655.93t、硬阔混交林为52 011.58t;天然林碳密度平均为179.26t CO_2-e·hm^(-2),人工林碳密度平均为88.03tCO_2-e·hm^(-2),天然林碳密度比人工林高,是人工林的103.64%。

Carbon storage and carbon density of plantation and natural forest in Longshan Forest Farm were calcu lated. Result shows that the total amount of carbon dioxide fixation for 10 kinds of forest types are 1,130,800 t. The carbon storage of the plantation of Pinus koraiensis ,Lari3c gmelinii ,Pinus sylvestris var. mongolica,Picea aspe rata, Quercus mongolica , Betula platyphylla , Populus davidiana , Tilia tuan , soft leaved mixed forest, broad - leaved mixed forest is 57 085.86 t,94 395.86,77 493.36 t,540.8 t,838 309.87 t,3 306. 04 t,1 890.56 t,2 102.03 t, 3 655.93 t,52 011.58 t, respectively. The mean carbon density of natural forest are 179.2G tCO2-e hm 2,the mean carbon density of plantation is 88.03 tCO2 -e hm 2 ;carbon density of natural forest is higher than that of the plantation;carbon density of natural forest is 103. 64% as large as that of plantation.
