| 英文摘要: | Forest degradation is a global environmental issue, but its definition is problematic. Difficulties include choosing appropriate reference states, timescales, thresholds, and forest values. We dispense with many such ambiguities by interpreting forest degradation through the frame of ecological resilience, and with reference to forest dynamics. Specifically, we define forest degradation as a state of anthropogenically induced arrested succession, where ecological processes that underlie forest dynamics are diminished or severely constrained. Metrics of degradation might include those that reflect ecological processes shaping community dynamics, notably the regeneration of plant species. Arrested succession implies that management intervention is necessary to recover successional trajectories. Such a definition can be applied to any forest ecosystem, and can also be extended to other ecosystems. Forest degradation results in biodiversity loss, greenhouse gas emissions, and diminution of ecosystem goods and services, but scientists, practitioners, and policy-makers are unable to agree a framework for defining degradation. Forests are spatially and temporally dynamic, and this stymies the selection of appropriate reference states, timescales, and thresholds against which degradation might be determined. Degradation is often defined as reduced capacity to provide goods and services. This definition takes little account of forest resilience - the ability of a system to reorganize and recover following disturbance. Advances in describing and quantifying ecosystem functioning have been fundamental in understanding forest dynamics, and provide a promising framework by which degradation might be better understood and, ultimately, defined. © 2015 Elsevier Ltd. |
