海洋食物网结构稳定性及干扰响应研究综述OA北大核心CSTPCD

A review of stability of marine food web structures and response to disturbance

中文摘要英文摘要

海洋食物网是海洋生态系统运行的核心机制之一,其复杂性和多维度稳定性保障了生态平衡、促进能量流动和物质循环,并且对生物多样性的维系至关重要.人类活动如过度捕捞、污染排放等可能对食物网结构造成干扰,进而影响到整个海洋生态系统的生产力和服务功能.同时,随着气候变暖和海洋酸化等全球变化进程的推进,食物网的结构和功能可能会发生改变,这不仅影响现有生态系统的动态平衡,还关系到未来海洋生态系统的适应能力和恢复潜力.本文梳理了食物网结构稳定性在不同维度的概念,总结稳定性与复杂性之间的内在联系.通过综述不同类型干扰如何作用于海洋食物网,从网络重构、物种更替、群落演变等角度揭示食物网在应对干扰时的适应机理.最后指出了当前海洋食物网研究过程中存在的局限性,例如数据获取难度大、食物网模型对动态过程的模拟不足以及种群功能界定的精度不够等问题,为未来海洋食物网研究提供改进方向.

The marine food web constitutes a core mechanism within marine ecosystems,with its complexity and multidimensional stability ensuring the maintenance of ecological balance,promoting energy flow and material cycling,and playing a critical role in preserving biodiversity.Human activities such as overfishing and pollution discharge may disrupt the structure of the food web,consequently impacting the productivity and service functions of the entire marine ecosystem.Concurrently,under the progression of global changes like climate warming and ocean acidification,the structure and functionality of the food web are likely to undergo alterations,which not only affect the current dynamic equilibrium of ecosystems but also bear upon the adaptability and resilience of future marine ecosystems.Thepaper employs ecological network analysis to systematically review and organize the concepts of food web structural stability across various dimensions,elucidating the intrinsic relationship between stability and complexity.Through an extensive overview of how different types of disturbances act on the marine food web,the paper uncovers the adaptive mechanisms at play from perspectives including network reconfiguration,species substitution,and community evolution.Finally,the paper highlights existing limitations in current research on marine food webs,such as the difficulty in acquiring data,insufficient modeling of dynamic processes in food web models,and inadequate precision in defining population functions.These insights provide directions for improvement in future studies of marine food webs,aiming to gain a more comprehensive understanding of their responses to environmental changes.
