生态系统服务权衡与协同研究：发展历程与研究特征

生态系统服务与人类福祉密切相关,生态系统服务之间的权衡协同关系是当前的研究重点,分析其概念内涵与研究特征,能够更好地认识区域生态系统服务之间的关系,从而面向各方需求实现总体效益最大化,为区域发展提供决策依据.本文采用文献分析法和比较分析法统计了国内外1996—2020年生态系统服务权衡与协同研究的文献数量特征,梳理了国内外自发展起始至当前不同时段的研究主题,归纳了生态系统服务权衡与协同的概念内涵和研究特征,指出了目前研究存在的不足以及未来的研究方向.研究表明:国内外文献数量均处于持续增长的趋势,并且国外增长速度高于国内;生态系统服务权衡与协同具有很强的时空尺度依赖性,时空尺度的差异共同驱动权衡协同关系的动态变化,但是目前该领域相关研究仍有很大的探索空间,未来需加强时空变化的框架模型、定量分析、驱动机制、内在机理、阈值效应、供给与需求等方面的研究,从而更好地认识生态系统服务权衡与协同的时空变化机理,实现区域生态环境与社会经济发展的双赢.

Trade-offs and synergies of ecosystem services: Development history and research characteristics

Ecosystem services are closely related to human well-being, and the study of the trade-offs and synergies between ecosystem services is currently a pressing research topic. By analyzing its conceptual connotation and research characteristics, we can better understand the relationship between the regional ecosystem services, adapt to the need of the parties to maximize the overall benefits, and provide a basis for decision-making for regional development. This study focused on the literature quantitative characteristics of domestic and foreign research on ecosystem services trade-offs and synergies from 1996 to 2020 by literature analysis and comparative analysis. Domestic and foreign research themes from different periods, from the beginning of development to the present, were analyzed. The conceptual connotation and research characteristics of the trade-offs and synergies of ecosystem services were summarized. Finally, shortcomings existing in current research and future research directions were identified. The specific conclusions are as follows: the number of domestic and foreign studies is increasing, with the foreign growth rate faster than domestic; Ecosystem service trade-offs and synergies are strongly dependent on time and space scales, the difference of spatio-temporal scale jointly drives the dynamic change of the relationship between trade-offs and synergies, but there is still a lot of research space in this field. In the future, it is necessary to strengthen the research on the framework model, quantitative analysis, driving mechanism, internal mechanism, threshold effect, supply and demand of temporal and spatial changes to better understand the mechanism of temporal and spatial changes in ecosystem service trade-offs and synergies, and achieve a mutually beneficial situation for regional ecological environment and socioeconomic development.
