The concept of 'environmental resilience' has gained traction in ecological studies, referring to an ecosystem's capacity to absorb disturbances while maintaining its fundamental structure and functions. Unlike mere resistance, which implies a static defense against change, resilience involves dynamic adaptation. For instance, a coral reef that bleaches under thermal stress but subsequently recovers with a different species composition demonstrates resilience, not resistance. Recent research suggests that biodiversity plays a crucial role in enhancing resilience, as diverse communities are more likely to contain species capable of thriving under altered conditions. However, human-induced pressures, such as pollution and overexploitation, can erode this natural buffer, pushing ecosystems beyond their tipping points. Consequently, conservation strategies increasingly focus on preserving not just current states but the adaptive capacities of ecosystems, acknowledging that dynamic change is inevitable in the Anthropocene.
❓ 根据文章所述,生态系统中恢复力与抵抗力的关键区别是什么?
A. A) 韧性涉及静态防御,而抗性涉及动态适应。
B. B) 韧性指的是在干扰后的恢复能力,而抗性则意味着在干扰下保持不变。
C. C) 韧性仅适用于珊瑚礁,而抵抗力适用于所有生态系统。
D. D) 恢复力降低生物多样性,而抵抗力则增强生物多样性。
✅ 正确答案
B) Resilience refers to recovery after disturbance, while resistance means withstanding disturbance without change.
