摘要：

Chinese fir (Cunninghamia lanceolata) is not only a valuable timber species, but also plays an important role in the provision of ecosystem services. Forest management decisions to increase the production of fiber for economic gain may have negative impacts on the long-term flow of ecosystem services from forest resources. Such tradeoffs should be taken into account to fulfill the requirements of sustainable forest management. Here we employed an established, ecosystem-based, stand-level model (FORECAST) in combination with a simplified harvest-scheduling model to evaluate the potential tradeoffs among indicators of provisional, regulating and supporting ecosystem services in a Chinese-fir-dominated landscape located in Fujian Province as a case study. Indicators included: merchantable volume harvested, biomass harvested, ecosystem carbon storage, CO2 fixation, O-2 released, biomass nitrogen content, pollutant absorption, and soil fertility. A series of alternative management scenarios, representing different combinations of rotation length and harvest intensity, were simulated to facilitate the analysis. Results from the analysis were summarized in the form of a decision matrix designed to provide a method for forest managers to evaluate management alternatives and tradeoffs in the context of key indicators of ecosystem services. The scenario analysis suggests that there are considerable tradeoffs in terms of ecosystem services associated with stand and landscape-level management decisions. Longer rotations and increased retention tended to favor regulating and supporting services while the opposite was true for provisional services. (C) 2016 Elsevier B.V. All rights reserved.
