Abstract

Realized ecosystem services (ES) are the actual use of ES by societies, which is more directly linked to human well-being than potential ES. However, a general analysis framework is lacking to understand how much ES was realized. In this study, we first proposed a Supply-Demand-Flow-Use (SDFU) framework that integrates the supply, demand, flow, and use of ES and differentiates these concepts into different aspects (e.g., potential vs. actual ES demand, export and import flows of supply, etc.). Then, we applied the framework to two examples of ES that can be found in typical urban green parks (i.e., pollination and recreation). We showed how the framework could assess the actual use of ES and identify the supply-limited, demand-limited, and supply–demand-balanced types of realized ES. We also explained the scaling features, discussed the temporal dynamics and spatial characteristics of realized ES, and asked several critical questions for future studies. Although facing challenges, we believe that the applications of the SDFU framework can provide a systematic way to accurately assess the actual use of ES and better inform policy-making for the sustainable use of nature’s benefits. Therefore, we hope our study will stimulate more research on realized ES and contribute to a deeper understanding of their roles in enhancing human well-being.

供应、需求、流动和使用综合分析框架,更好地了解已实现的生态系统服务
已实现的生态系统服务(ES)是社会对生态系统服务的实际利用,与潜在的生态系统服务相比,它与人类福祉的联系更为直接。然而,目前还缺乏一个通用的分析框架来了解实现了多少生态系统服务。在本研究中,我们首先提出了 "供应-需求-流动-使用"(SDFU)框架,该框架综合了生态系统服务的供应、需求、流动和使用,并将这些概念区分为不同的方面(如潜在与实际的生态系统服务需求、供应的出口和进口流动等)。然后,我们将该框架应用于典型城市绿地公园中的两个 ES 例子(即授粉和休闲)。我们展示了该框架如何评估生态系统服务的实际使用情况,以及如何识别供应受限型、需求受限型和供需平衡型的已实现生态系统服务。我们还解释了缩放特征,讨论了实现的生态系统服务的时间动态和空间特征,并为未来研究提出了几个关键问题。尽管面临挑战,但我们相信,SDFU 框架的应用可以为准确评估 ES 的实际使用情况提供系统方法,并为可持续利用自然惠益的政策制定提供更好的信息。因此,我们希望我们的研究能激发更多关于已实现的生态系统服务的研究,并有助于更深入地了解它们在提高人类福祉方面的作用。

期刊介绍: Ecosystem Services is an international, interdisciplinary journal that is associated with the Ecosystem Services Partnership (ESP). The journal is dedicated to exploring the science, policy, and practice related to ecosystem services, which are the various ways in which ecosystems contribute to human well-being, both directly and indirectly. Ecosystem Services contributes to the broader goal of ensuring that the benefits of ecosystems are recognized, valued, and sustainably managed for the well-being of current and future generations. The journal serves as a platform for scholars, practitioners, policymakers, and other stakeholders to share their findings and insights, fostering collaboration and innovation in the field of ecosystem services.
