Abstract： Aims To clarify the status of the carbon storage of forest ecosystem at different ages in Anhui Province, and to identify the maximum carbon sequestration potential of climax forest controlled by current natural environment conditions. Methods Field investigation method and BIOME4 model. Important findings At present, the total carbon storage of forests in Anhui Province is 714.5 Tg C, including 402.1 Tg C in vegetation and 312.4 Tg C in soil. Generally, the total and vegetation carbon density always present an increasing trend in the natural growth process of forest ecosystems in Anhui Province. Soil carbon density increases at the periods from young to near mature forests, but decreases gradually after near mature forest. Young and middle-aged forests account for 75% of the total forests area in Anhui Province, and there will be a potential additional carbon of 125.4 Tg C in case of young and middle-aged forests developing to near mature stand stage. Results from BIOME4 simulation showed that there will be a potential additional carbon of 245.7 Tg C (i.e. total carbon sequestration), including vegetation carbon sequestration of 153.7 Tg C, and soil carbon sequestration of 92 Tg C if forests develop to climax forest ecosystems in Anhui Province.
