摘　　要：利用邻水县2020年森林资源数据资料和IPCC材积源—生物量法,研究估算了邻水县2020年林地碳储量和碳密度,结果为:2020年邻水县总碳储量为134.7万吨,平均碳密度为23.59 mg·hm^(-2),林地碳储量无论是天然林还是人工林,都主要储存在成熟林中;林地平均总碳密由大到小依次是成熟林、过熟林、中龄林、近熟林、幼龄林,其中天然林碳密度近熟林>成熟林>中龄林>幼龄林,人工林碳密度成熟林>过熟林>中龄林近熟林>幼林林;乔木林碳储量主要分布在森林公园、林场以及森林资源比较丰富的乡镇;同龄级不同类型乔木林的面积与蓄积量各不相同,碳汇能力表现各异。Based on the forest resource data of Linshui County in 2020,this paper estimated the total carbon storage and carbon density of Linshui County in 2020 using the IPCC volume source and biomass method.The results showed that the total carbon storage of Linshui County in 2020 is 1.347 million tons,and the average carbon density is 23.59 mg/hm2.The comprehensive analysis showed that the carbon storage of natural forest and artificial forest was mainly stored in mature forest.The total carbon density of natural forest from large to small was in the order of mature forest,over mature forest,middle aged forest,near mature forest and young forest.The carbon density of natural forest from large to small was in the order of near mature forest,mature forest,middle aged forest and young forest.The carbon density of artificial forest decreased from large to small in the order of mature forest,over mature forest,middle age forest,near mature forest and young forest.The carbon storage of arboreal forests in Linshui County is mainly distributed in forest parks,forest farms,and towns with rich forest resources.With the same age class,the area and growing stock of different types of arbor forests are different,and the carbon sequestration capacity is different.
