As an effort to provide a benchmark for the CDM afforestation project, dynamics of carbon sequestration potential for both indigenous forests and non\|forested lands in Fujian Province was modeled using a computerized ecological model known as CO2FIX V3.1. Two human interference scenarios, harvesting and non\|harvesting, were simulated. Simulation results suggested that the net carbon sequestrated by indigenous forest ecosystem between 2004 and 2050 may reach 254.74-334.79TgC, while afforestation practices during the same period may fix additional 49.23-58.42TgC. With high proportions among all forest species, Pinus massoniana, Cunninghamia lanceolata, and Hardwood may solidify carbon dioxide up to 92.26-103.17TgC, 71.09-107.39TgC, and 114.97-132.41TgC, respectively. All nine prefecture\|level cities in Fujian were rank ordered using the model output, with Nanping, Fuzhou, and Sanming presenting the greatest potential in carbon sequestration, Longyan, Zhangzhou, and Ningde in the middle, and such costal cities as Putian, Quanzhou, and Xiamen tailing the list.
