基于生态系统服务权衡的生态系统管理策略研究进展
Research progress in ecosystem management strategies based on ecosystem services trade-offs
【摘要】 生态系统服务是连接社会系统与生态系统间的桥梁,根据生态系统服务间此消彼长的权衡关系制定生态系统管理策略是进行生态系统可持续管理的重要前提。本文旨在对基于生态系统服务权衡的生态系统管理策略进行全面总结,并针对现有管理策略的不足提出潜在解决方案。按照需求—需求权衡、供给—需求权衡和供给—供给权衡分类体系,系统梳理了国内外基于生态系统服务权衡的生态系统管理策略,并在现有管理策略的基础上创新地提出了耦合三种权衡的生态系统管理框架。结果显示:需求—需求权衡管理策略的实质是生态系统服务优先级排序,供给—需求权衡主要通过调控供需权衡驱动力以改变生态系统服务供给量与需求量,供给—供给权衡主要依据权衡特征进行分区管理,或者调控权衡驱动力提高ES供给量并缓解权衡强度。研究表明:(1)生态系统管理的目标是缓解供给—需求权衡强度,同时达到“效率性”与“公平性”两个管理要求,即缓解供给—需求权衡强度的同时缓解供给—供给权衡与需求—需求权衡。现如今管理策略大多孤立地缓解某一种生态系统服务权衡,缺少耦合三种生态系统服务权衡的生态系统管理框架。(2)优先缓解主客观重要性较高生态系统服务的供给—需求权衡强度可同步缓解需求—需求权衡,综合调控供需权衡驱动力与供给权衡驱动力可同时缓解供给—需求权衡强度与供给—供给权衡,从而最终实现三种权衡的耦合。
【Abstract】 Ecosystem services are the bridge between social system and ecosystem. It is an important prerequisite for sustainable ecosystem management to formulate ecosystem management strategies based on the ecosystem services trade-offs. This study aims to provide a comprehensive summary of ecosystem management strategies based on ecosystem services tradeoffs and to propose potential solutions to the deficiencies of existing management strategies.Based on the classification system of demand-demand trade-offs, supply-demand trade-offs and supply-supply trade-offs, this study systematically reviewed the ecosystem management strategies based on ecosystem service trade-offs at home and abroad, and innovatively proposed an ecosystem management framework coupled with three types of trade-offs. The research results show that the essence of the demand-demand trade-offs management strategy is the prioritization of ecosystem services. Supply-demand trade-off mainly changes the supply and demand of ecosystem services by regulating the driving forces of supply-demand trade-off, and the supplysupply trade-off is mainly managed by zoning according to the tradeoff characteristics, or regulating the driving forces of trade-off to increase the supply of ES or relieve the trade-off strength. The research shows that:(1) The goal of ecosystem management is to alleviate the strength of supply-demand trade-offs and achieve the two management requirements of "efficiency" and "fairness". That is, to ease the strength of the supply-demand trade-offs and simultaneously ease the supply-supply trade-offs and the demand-demand trade-offs. Currently, most management strategies are designed to alleviate one ecosystem services trade-offs in isolation and lack an ecosystem management framework coupling the three ecosystem service trade-offs.(2) Prioritizing mitigation in the supply-demand trade-off intensity of ecosystem services with higher subjective and objective importance can simultaneously alleviate the demand-demand trade-off. Comprehensively regulating the driving forces of supply and demand trade-offs and supply trade-offs can simultaneously alleviate the strength of supply-demand trade-offs and supply-supply trade-offs. Finally, the coupling of the three trade-offs is achieved.
