近30a陕西省森林植被碳储量及其动态变化
Forest Carbon Storage and Its Dynamic Change in Shaanxi Province in Recent 30 Years
摘要
Abstract
The IPCC method was used to estimate the dynamic change of the forest carbon storage and carbon density in Shaanxi Province in recent 30 years using the inventory data in seven periods from 1987 to 2014.The results showed that the forest carbon storage and carbon sink in Shaanxi Province were significantly increased in recent 30 years,and the forest carbon storage was increased from 121 million tons in 1987 to 238 million tons in 2014,the net increase was 117 million tons,and the average annual increase rate was 2.3％.Especially since the 21th century,the effect of forest carbon sink was the strongest,the net carbon sink amount was 85 million tons,and the contribution to total forest carbon sink was 72.65 ％.There was an inverse correlation between the annual forest carbon sink and the forestry harvest volume.Thehttp://dict.cnki.net/dict_result,aspx? searchword =％ e4％ b8％ 8d％ e5％90％ 8c％ e8％ b5％ b7％ e6％ ba％ 90&tjType =sentence&style =&t =different + original forest carbon storage,carbon density and carbon sink capacity of natural forest were much higher than those of artificial forest,and the natural forests were the main contributors to the carbon storage and carbon sink in Shaanxi Province.In different forest types,the quercus,hard broad-leaf species and soft broad-leaf species were the main contributors to the forest carbon storage.The carbon storage was mainly in the near-mature forest,mature forest and over-mature forest with low proportions.There was a positive correlation between the carbon density and the forest age.关键词
