【 摘 要 】

Carbon storage in forests in Inner Mongolia Autonomous Region plays a significant role in the terrestrial carbon budget due to its largest forest coverage and forest growing stock among all the provinces in China. Nevertheless, scientific research on forest carbon is comparatively less as compared with the research on the main ecosystem, steppe in this area. We are still short of knowledge of forest carbon sequestration's rate, mechanism and potential in the area. Now we are conducting a research program aiming at making clear the above scientific issues. So knowing well previous research work and key findings is essential and helpful for our underway study. In this paper we reviewed the current knowledge, opportunity and challenges of forest carbon research in Inner Mongolia. The total carbon storage in forest of this region increased significantly from 0.417Pg carbon in 1949 to 0.719Pg carbon in 2008 with an annual increase of 2.842Tg∼5.226Tg carbon and a dramatically increment of carbon storage in shrub. Carbon storage varied with dominant tree species, forest age and forest growth situation with an average forest carbon density of 42.68 t-C·hm-2, displaying a downtrend before 1980 and later a slow smooth uptrend. It is suggested that increase in vegetation carbon sequestration potential be achieved through selection of plant species and forest management.
