The trends in the provision of ecosystem services during restoration and succession of subtropical forests and plantations were quantified, in terms of both receiver and donor values, based on a case study of a 3-step secondary succession series that included a 400-year-old subtropical forest and a 23-year history of growth on 3 subtropical forest plantations in Southeastern China. The 'People's Republic of China Forestry Standard: Forest Ecosystem Service Valuation Norms' was revised and applied to quantify the receiver values of ecosystem services, which were then compared with emergy-based, donor values of the services. The results revealed that the efficiencies of subtropical forests and plantations in providing ecosystem services were 2 orders of magnitude higher than similar services provided by the current China economic system, and these efficiencies kept increasing over the course of succession. As a result, we conclude that afforestation is an efficient way to accelerate both the ability and efficiency of subtropical forests to provide ecosystem services. The ability of different ecosystems to provide services depends on the concentration of available natural resources in the system at a large scale, but also on the ability of the ecosystems to capture natural resources in the same or similar environments.
基于中国东南部一个包含400年历史的亚热带森林以及3个亚热带人工林23年生长历程的3阶段次生演替系列案例研究，从受体价值和供给者价值两方面对亚热带森林和人工林恢复及演替过程中生态系统服务供给趋势进行了量化。修订并应用《中华人民共和国林业行业标准：森林生态系统服务功能评估规范》来量化生态系统服务的受体价值，然后将其与基于能值的服务供给者价值进行比较。结果表明，亚热带森林和人工林提供生态系统服务的效率比当前中国经济系统提供类似服务的效率高2个数量级，且这些效率在演替过程中持续增加。因此，我们得出结论，造林是提高亚热带森林提供生态系统服务的能力和效率的有效途径。不同生态系统提供服务的能力不仅取决于系统中大规模可用自然资源的浓度，还取决于生态系统在相同或相似环境中获取自然资源的能力。
