摘要
作为沟通自然生态系统与人类社会的重要桥梁,生态系统服务一直以来都是地理学、生态学等学科的研究前沿和热点。正确认知生态系统服务之间的关系,是开展多种生态系统服务可持续管理决策的前提,有助于人类福祉的全面提升。本文通过厘定生态系统服务权衡的概念内涵,梳理了生态系统服务权衡的空间、时间和可逆性特征,将多层次人类福祉的满足作为权衡的最终目标,视生态补偿为权衡决策的基本保障途径。生态系统服务权衡关系的识别依托于定量指标法和综合模型法,且权衡关系可能随时空尺度的推移发生改变;情景分析与多目标分析是生态系统服务权衡决策的有效手段。生态系统服务权衡多尺度关联、生态系统服务流与远程耦合、生态系统服务消费与生态补偿,成为当前生态系统服务权衡研究的重点方向。
As a hot spot in geography, ecology and related disciplines, ecosystem services have been playing a vital role in bridging the human society with the ecosystem. A deep understanding of the relationship among ecosystem services is a critical enabling factor for sustainable management and decision-making in multiple ecosystem services, in turn realizing the dual goals of economic development and ecological protection and thus contributing to the overall wellbeing of human. Through a systematic review of the concept of ecosystem service trade-offs, this article explores their characteristics in terms of spatial scales, temporal scales and reversibility, considering human＇s wellbeing at different levels as the ultimate goal of ecosystem service trade-offs and ecological compensation as a baseline method of protection in trade-offs. Such ecosystem services trade-offs are expressed by quantitative indexing and integrated modelling. While such trade-offs and synergies among ecosystem services could present significant variations by spatial and temporal scales, scenario simulation and multi-objective analysis are effective ways to support decision-making in ecosystem service trade-offs. Based on these findings, the multi-scale correlation of ecosystem service trade-offs, the flow of ecosystem service based on telecoupling, and the consumption and compensation of ecosystem services are identified to be the main directions for future research on ecosystem service trade-offs.
