摘要
在全球变化背景下,全球陆地植被生态系统如何响应和适应日益加剧的干旱环境,即干旱胁迫下植被生态韧性的空间格局和演变机理,成为当前生态学和生态水文学研究的核心内容之一。近年来,围绕植被变化与水分胁迫关系的研究不胜枚举,对其机理的认识不断深入。然而,对于植被生态韧性的阐释仍存在较大的分歧和争议,主要原因之一是对生态韧性内涵的理解尚未统一。针对这一问题综合了国内外学者的观点,认为解析生态韧性不仅应当考虑干旱事件下的系统抵抗和恢复能力,更应从系统演化的角度解析变化环境下的系统应对与适应行为,即抵抗力、恢复力和适应性应该是衡量生态韧性的3个最重要的维度。围绕这3个主要维度梳理了国内外近期研究成果,从生态韧性特征的空间格局、影响机理以及适应策略方面,总结了学术界当前对生态韧性的主要认识和待解决的关键问题。旨在通过对生态韧性概念的辨析和研究现状的梳理,促进学界就生态韧性的界定及其定量方法方面展开讨论,从而为解释韧性演变规律及其内在机理奠定基础。
Ecological resilience,the ability of an ecosystem to absorb and adapt to environmental change to maintain its sustainability,was first systematically introduced by the Canadian ecologist C.S.Holling in 1973 and has since rapidly attracted attention and been used across multiple disciplines.In the context of global change,the response of terrestrial ecosystems to increasingly intensifying arid environments,specifically the spatial patterns and evolutionary mechanisms of vegetation ecological resilience under drought stress,has become a core focus of current ecological and ecohydrological research.In recent years,numerous studies have been conducted on the relationship between vegetation change and water stress,enhancing our understanding of this mechanism.However,the interpretation of the ecological resilience of vegetation varies widely and remains controversial,and one of the main reasons for this is that the understanding of the connotations of ecological resilience is not yet unified.To address this issue,we synthesized the views of researchers worldwide and suggested that the analysis of ecological resilience should not only consider the system resistance and recovery capacity under drought events but also the system response and adaptation behavior under changing environments from the perspective of system evolution.These include resistance,recovery,and adaptation,which should be the three most important dimensions for determining ecological resilience.Focusing on these three main dimensions,we reviewed the results of recent research conducted globally and summarized the current understanding of ecological resilience and the key issues to be addressed in terms of spatial patterns,impact mechanisms,and adaptation strategies for ecological resilience.Through an analysis of the concept of ecological resilience and the current state of research,we hope to promote academic discussions on the definition of ecological resilience and its quantitative methods to facilitate an understanding of the evolution of resilience and its underlying mechanisms.
