The concept of 'ecological resilience' has gained prominence in environmental science as a framework for understanding how ecosystems respond to disturbances. Unlike traditional stability, which emphasizes return to a pre-disturbance state, resilience focuses on the capacity of a system to absorb shocks, reorganize, and maintain its essential functions. A resilient ecosystem may shift to a new state that is functionally similar but structurally distinct. This perspective challenges management strategies that aim solely at preserving historical conditions, suggesting instead that adaptive governance should anticipate change and foster diversity. Critics argue, however, that resilience theory is difficult to operationalize due to vague metrics and the complexity of defining thresholds. Nevertheless, it remains a valuable heuristic for policy-making in an era of rapid global change.
❓ According to the passage, what is a key difference between traditional stability and ecological resilience?
A. Traditional stability prioritizes structural change, while resilience focuses on returning to original conditions.
B. Traditional stability emphasizes returning to a pre-disturbance state, while resilience allows for functional continuity despite structural change.
C. Resilience rejects the idea of absorbing shocks, whereas stability encourages system reorganization.
D. Resilience is only applicable to marine ecosystems, while stability applies to terrestrial ones.
✅ 正确答案
Traditional stability emphasizes returning to a pre-disturbance state, while resilience allows for functional continuity despite structural change.
