长期森林恢复实验项目（FREP）于1991年在中国江西省泰和县的亚热带、贫瘠、退化、地形起伏的红土上建立。FREP的目的是评估通过造林各种当地顶极物种恢复对生态功能的影响，为中国南方常见的严重退化景观的未来恢复项目提供指导。在这项研究中，我们选择了五个恢复森林：枫香（Liquidamber formosana），木荷（木荷极好），马尾松（Pinus massoniana），湿地松（湿地松）、枫香×湿地松混交林和一个试验对照（自然恢复），以评估碳储存和碳库结构的差异，包括地上和地下碳库、森林地面凋落物、木质残体、土壤有机碳（SOC）还根据所研究物种的分组，对物种功能组（针叶林、阔叶林和混合物种林-阔叶林×针叶林物种混合物）进行了类似的评估。我们还通过与当地生态系统的比较，评估了FREP的万年青阔叶林的恢复轨迹。在19年的研究期间，在5个恢复类型的总生态系统碳（TEC）储量显着高于对照，但有没有显着差异的TEC库存之间的恢复类型。枫香、木荷、马尾松、湿地松和混交林的TEC分别为119 MgCha-1、118 MgCha-1、105 MgCha-1、104 MgCha-1和124 MgCha-1。然而，有一个显着的变化，在恢复功能组之间的碳库结构。阔叶林和混交林土壤有机碳库分别显著高于针叶林25%和16%。这种差异可以用恢复轨迹来解释，这表明森林资源保护方案中的万年青林（木荷）仍处于早期发展阶段，其预测增长率比该区域的平均增长率低得多。这项研究清楚地表明，主动恢复可以提高生态系统的碳固存。显然，一个长期的监测计划是至关重要的，以获得更多的信息，这将使我们能够推断我们的研究结果，更广泛的恢复计划，并增加恢复森林的固碳强度。
The long-term Forest Restoration Experimental Project (FREP) was established in 1991 on a sub-tropical, barren, degraded, red soil with a rolling terrain located in Taihe County, Jianxi province, China. The objective of the FREP was to evaluate the effects of restoration, through afforestation of various local climax species, on ecological functions to provide guidance for future restoration projects on severely deteriorated landscapes, which are very common in southern China. In this study, we selected five restoration forests: Chinese sweetgum (Liquidamber formosana), schima (Schima superb), masson’s pine (Pinus massoniana), slash pine (Pinus elliottii), Chinese sweetgum×slash pine mixtures, and one experimental control (natural recovery) to evaluate the differences in carbon storage and pool structures, including above- and below-ground carbon pools, forest floor litter, woody debris, and soil organic carbon (SOC). A similar assessment was also conducted on the species functional groups (coniferous forest, broad-leaved forest, and mixed-species forest – broad-leaved×coniferous species mixture) based on groupings of studied species. We also evaluated the recovery trajectory of FREP’s evergreen broad-leaved forest by comparing it with local ecosystems. Over the 19-year study period, the Total Ecosystem Carbon (TEC) stocks in the five restoration types were significantly higher than that in the control sites, but there were no significant differences in the TEC stock among the restoration types. The TEC was 119MgCha−1for Chinese sweetgum, 118MgCha−1for schima, 105MgCha−1for masson’s pine, 104MgCha−1for slash pine, and 124MgCha−1for the mixture. However, there was a significant variation in the carbon pool structure among restoration functional groups. The SOC pool sizes of broad-leaved and mixed-species forest were 25% and 16% significantly higher than the coniferous forest, respectively. This difference may be explained by the recovery trajectory, which suggests that the evergreen forest (schima) in FREP is still in the early developmental stage, and its projected rate of growth is much slower than the average growth rate in the region. This study clearly demonstrated that active restoration can enhance ecosystem carbon sequestration. Clearly, a long-term monitoring program is critical for obtaining more information that will enable us to extrapolate our findings for broader restoration plans and to increase the carbon sequestration strength of restored forests.
