    摘要:

    利用CO2FIX V3.1模型对福建省原有森林生态系统和无林地造林两部分的碳汇潜力动态变化进行计算,为CDM造林碳汇项目的开展提供参考。假设采伐、非采伐两种情景,模拟显示福建省原有森林生态系统2004至2050年可净固定大气碳量为254.74—334.79TgC,而无林地造林可净固定大气碳量49.23—58.42TgC。马尾松、杉木及硬阔类的面积在福建省森林中占较大比重,自2004至2050年,三者可分别固碳92.26—103.17TgC、71.09—107.39TgC和114.97—132.41TgC。在福建省9个地级市中,南平、福州和三明的无林地造林碳汇潜力最大,龙岩、漳州、宁德次之,沿海的莆田、泉州和厦门最小。

    Abstract:

    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.
