- Abstract:
-
Based on the forest inventory data of China, the carbon storage and carbon density of forest vegetation in Yellow River Basin were assessed by means of the regression equation between vegetation biomass and volume, and with the carbon fraction of dry matter. The results showed that during the period 1989-2008, total carbon storage of forest vegetation increased from 131.15 Tg C to 265.63 Tg C in the Yellow River, the percentage increased from 2.83% to 4.18% of carbon storage of the national forest vegetation; and the average carbon density of forest vegetation was 34.47~39.00 Mg/hm2 during the period; the distribution of the carbon storage in the Yellow River Basin was not significantly different among all forest age groups from 2004 to 2008, ranging from 46.64 to 68.31 Tg C; the carbon storage of natural forests mainly distributed in middle-aged and over-mature forest, mature forest, near-mature forest; and carbon storage of planted forest mainly concentrated in young and middle-aged forests; the average carbon densities of forest vegetation, natural forest and planted forest in the basin all showed the increasing trend with the increase of forest ages. The carbon storage of natural forest in the Yellow River Basin was 3.5 to 4.5 times higher than that of planted forests; the carbon storages of both natural forests and planted forest showed an increasing trend over time; the carbon storage of forest vegetation in the Yellow River Basin mainly concentrated in the upper and middle reaches of the Yellow River, accounting for more than 97% of the whole basin; the carbon storage of forest vegetation in the upper, middle and lower reaches of the Yellow River Basin from 2004 to 2008 increased by 7.61%, 13.13% and 136.98%, respectively, compared to those in the period 1999-2003. Furthermore, the results also showed that the forest in the Yellow River Basin would play an important role in enhancing national forest carbon sequestration due to higher carbon sequestration in the forest in comparison with national level, and the huge potential for carbon sequestration in the future.
