Abstract

Landscape sustainability depends on the design of landscape patterns that can be guided by ecosystem services (ESs). Clarifying the impacts of landscape configurations on ESs and their trade-offs will facilitate landscape planning and management to achieve the best design without changing most landscape compositions. However, limited work has focused on these impacts, and whether these impacts are the same on different compositions remains unexplored. Thus, this study analyzes the impacts of landscape configurations on ESs and their trade-offs for different compositions. In this analysis, Gaussian mixture model was used to cluster the landscape by compositions, five important ESs (crop production, water yield, carbon storage, soil retention, and outdoor recreation) were quantified, and the constraint line was used to analyze the impact, taking the Xiangjiang River Basin as an example. Results showed that three clusters of landscape compositions, which are similar to the urban–rural–natural gradient, were identified. Furthermore, the impacts of landscape configurations on ESs and their trade-offs had largely the same direction in different compositions. However, change in landscape composition makes the high correlations among them weaker or shift to constraint impacts. Based on the results of the study, we can not only contribute to local landscape development but also argue three general approaches for landscape planning and management. First, considering the trade-offs and making a choice adapted to local conditions. Second, adjusting landscape configurations with virtually no changes of compositions. Third, external intervention based on rational landscape configurations.

不同景观组合对生态系统服务及其权衡的影响
景观的可持续性取决于景观模式的设计,这些模式可以由生态系统服务 (ES) 指导。明确景观配置对生态系统服务的影响及其权衡将有助于景观规划和管理,从而在不改变大多数景观构成的情况下实现最佳设计。然而,目前关注这些影响的工作还很有限,而且这些影响是否会对不同的组合产生相同的影响也仍未得到探讨。因此,本研究分析了景观配置对生态系统服务的影响及其对不同组成的权衡。分析中,以湘江流域为例,采用高斯混合模型对景观进行成分聚类,量化了五种重要的生态系统服务(作物生产、水资源产量、碳储存、土壤保持和户外休闲),并利用约束线分析其影响。结果表明,确定了与城市-农村-自然梯度相似的三个景观组合群。此外,在不同的景观组成中,景观配置对环境服务的影响及其权衡的方向大致相同。然而,景观组成的变化会削弱它们之间的高度相关性,或转变为限制性影响。根据研究结果,我们不仅可以为当地的景观发展做出贡献,还可以论证景观规划和管理的三种一般方法。第一,权衡利弊,因地制宜。第二,在几乎不改变构成的情况下调整景观配置。第三,在合理景观配置的基础上进行外部干预。

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.
