The Contribution and Potential of Natural Forests to Carbon Sink in China
摘要
Abstract
The carbon storage and carbon density of natural forests in China were calculated by biomass con-version factor method based on the data of 9 forest resource inventories,and the logistic growth equation was used to predict the carbon sink potential of natural forests in China during 2023-2063.The results showed that 1)during the inventory period of over 40 years,China's natural forest carbon storage had in-creased significantly,with a net increase of 2 369.502 7 million t and an increment rate of 65.27％.The carbon density as a whole showed a"rising-declining-rising"trend.2)Among the 9 inventory results,except for the second inventory in which the carbon sink value was in negative growth,all other periods showed positive carbon sink growth and the average carbon sink of the nine periods was 5.800 06 million t.3)In the seventh to ninth inventory,the top six provinces in terms of carbon storage contribution were Tibet(918.773 3-936.465 6)＞Yunnan(697.126 7-810.151 0)＞Heilongjiang(638.102 5-746.833 6)＞Sichuan(551.342 0-623.479 5)＞Inner Mongolia(497.950 4-617.869 9)＞Jilin(329.973 1-388.3395 million t),and the relationship between carbon stock contribution in different regions were Southwest China(42.54％-45.67％)＞Northeast China(20.29％-20.54％)＞North China(10.93％-11.56％)＞Central and South China(8.92％-9.86％)＞East China(7.13％-8.56％)＞Northwest China(6.81％-7.20％),and the carbon density relationships were all Southwest China(66.68-68.09)＞Northeast China(41.69-47.42)＞Northwest China(41.29-45.82)＞North China(32.38-39.18)＞East China(27.35-38.69)＞Central and South China(24.11-31.57 t·hm-2).4)The carbon sink potential of China's natural forests in 2030 under the Logistic growth equation amounted to 7 153.202 9 million t in 2030 and 8 676.207 1 million t in 2060,China's natural forest resources will play a huge role in the carbon neutrality target.关键词
