    Plantations in China are facing a series of issues, such as structure degradation and function reduction. Thus, it is urgently requested to implement effective measures on plantations through reasonable forest management strategies. The Moshao forest farm of Huitong ecological station, which is a typical forest ecosystem in Red Soil Hilly Region of South China, is the study area to examine the dynamics of forest area and aboveground biomass (AGB) in the next century. The landscape disturbance model named LANDIS-II was employed in this study to simulate the effects of harvesting intensities and artificial regeneration on artificial coniferous forest, artificial broad-leaved forest, and natural broad-leaved forest by six scenarios. The scenarios included low, middle, high harvest intensity and each scenario had an artificial regeneration option after harvesting. The results showed that as the harvesting intensity went heavier, the area of artificial coniferous forest decreased. Conversely, natural forest area increased. And the forest AGB decreased sharply when the harvesting intensity was high. Plantations could take advantages of artificial regeneration to remain the area and facilitate the AGB accumulation. The scheme of harvesting with 20% of plantations every 10 years and followed by artificial regeneration would basically retained the area and AGB at the initial level in the next century. Therefore, this scheme was more applicable to the long term development of the forest in the study area and helpful to achieve the forest sustainable management of Chinese fir and masson pine plantations.
