摘要

English

Multiple stable states - the coexistence of two or more distinct ecological configurations under identical environmental conditions - have attracted sustained interest in ecology, yet the field still lacks a unified framework connecting ecological mechanisms to dynamical models. Here, we review empirical and theoretical approaches to multiple stable states, synthesising perspectives on stability, tipping, hysteresis, and transient dynamics, and contextualise these within a common mathematical framework. Drawing on examples of well-known ecosystem models, we highlight the central and necessary role of positive feedback loops and identify other common, unifying features of ecological systems that exhibit multiple stable states. We further discuss the relationship between stable and transient dynamics, the roles of spatial and temporal scales in feedback identification, and the implications for ecological restoration and management. We conclude with open questions and challenges for the field, including extending multistability theory to persistent-transient frameworks and harnessing emerging data-collection technologies to sharpen empirical inference.

多重稳定状态——相同环境条件下两种或多种不同生态配置的共存——引起了生态学的持续关注,但该领域仍然缺乏连接生态机制和动力学模型的统一框架。在这里,我们回顾了多种稳定状态的经验和理论方法,综合了稳定性、倾斜、滞后和瞬态动力学的观点,并将这些观点置于共同的数学框架中。借鉴著名的生态系统模型的例子,我们强调了正反馈循环的核心和必要作用,并确定了表现出多种稳定状态的生态系统的其他共同的、统一的特征。我们进一步讨论稳定动态和瞬态动态之间的关系、时空尺度在反馈识别中的作用以及对生态恢复和管理的影响。最后,我们提出了该领域的开放性问题和挑战,包括将多稳定性理论扩展到持续瞬态框架,并利用新兴的数据收集技术来加强经验推理。

核心贡献

本文对生态学中的多重稳定状态(multiple stable states)现象进行了系统综述与理论综合。作者将分散在经验观察、数学建模、稳定性理论和生态管理中的概念整合进一个统一的数学框架。核心发现是:正反馈回路(positive feedback loops)是多重稳定状态的中心且必要的机制——它们同时充当每个稳定状态的自我维持引擎和状态间转换的开关(图1用势能景观和分岔图进行了直观阐释)。文中还系统梳理了空间代时间(space-for-time)替代法的数学基础及其局限性。

方法概述

这是一篇综述性论文,采用自上而下的综合方法:(1) 回顾历史发展脉络(1947年 Watt 的群落格局→1974年 Sutherland 的污损群落→现代定义);(2) 综合浅湖、珊瑚礁、热带森林-稀树草原等经典案例的数学模型和实证证据;(3) 构建统一的动力学框架:用向量场和势能景观的语言形式化稳定性、倾覆(tipping)、滞后(hysteresis)和瞬态动力学(transient dynamics)的定义;(4) 识别正反馈回路作为跨系统的统一特征;(5) 讨论空间-时间替代法的遍历理论(ergodic theory)基础及其在实际应用中的断裂。
