Clarifying the impact mechanisms of landscape patterns on ecosystem services is highly important for effective ecosystem protection, policymaking, and landscape planning. However, previous literature lacks knowledge about the impact mechanisms of landscape patterns on ecosystem services from a spatial perspective. Thus, this study measured landscape patterns and the ecosystem services value (ESV) using a series of landscape pattern metrics and an improved benefit transfer method based on land-use data from 2015. It explores the impact mechanisms of the landscape pattern metrics on the ESV using the ordinary least-squares method and spatial regression models in the middle reaches of the Yangtze River Urban Agglomerations (MRYRUA), China. We found that forestland was the main landscape type in the MRYRUA, followed by cultivated land, and the fragmentation degree of cultivated land was significantly higher than that of forestland. The findings demonstrate that landscape pattern metrics had a significant impact on ecosystem services, but could vary greatly. Moreover, ecosystem services in the MRYRUA exhibited significant spatial spillover effects and cross-regional collaborative governance was an effective means of landscape planning. This paper acts as a scientific reference and effective guidance for landscape planning and regional ecosystem conservation in MRYRUA and other similarly fast-growing urban agglomerations.
阐明景观格局对生态系统服务的影响机制对于有效的生态系统保护、决策制定和景观规划至关重要。然而，以往的文献缺乏从空间角度了解景观格局对生态系统服务影响机制的知识。因此，本研究使用一系列景观格局指标和基于 2015 年土地利用数据的改进效益转移方法来衡量景观格局和生态系统服务价值（ESV）。在中国长江中游城市群（MRYRUA），本研究利用普通最小二乘法和空间回归模型探讨了景观格局指标对 ESV 的影响机制。结果表明，林地是 MRYRUA 的主要景观类型，其次是耕地，耕地的破碎化程度明显高于林地。研究结果表明，景观格局指标对生态系统服务有显著影响，但影响程度差异很大。此外，MRYRUA 的生态系统服务存在显著的空间溢出效应，跨区域协同治理是景观规划的有效手段。本文为 MRYRUA 及其他类似快速增长的城市群的景观规划和区域生态系统保护提供了科学参考和有效指导。
