Dynamics of ecosystem services provided by subtropical forests in Southeast China during succession as measured by donor and receiver value

- Dynamics of ecosystem services provided by subtropical forest during succession.
- Forest ecosystem services was valued from both donor and receiver aspects.
- Quantify the efficiencies of subtropical forests in providing ecosystem services.

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 the 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.
