Abstract

Identifying ecosystem service functions, clarifying the spatiotemporal trade-offs and synergies of terrestrial ecosystem services and their driving mechanisms, and exploring differentiated ecological functional zoning are crucial steps in achieving healthy regional ecosystem management, and are conducive to developing diversified ecological restoration strategies, establishing a robust cross-regional collaborative management mechanism, implementing differentiated ecological management strategies, and contributing to the construction of a Beautiful China. This paper, based on the InVEST model, Pearson correlation, GeoDetector, and Spatiotemporal Geographically Weighted Regression models, constructs a spatial quantification model of the trade-offs and synergies among five key ecosystem service functions—habitat quality, soil retention, water conservation, food supply, and carbon sequestration—of China’s terrestrial ecosystems from 2000 to 2020. It explores the influencing factors of terrestrial ecosystem services in China and their spatiotemporal heterogeneity, thereby investigating the future strategies for ecological functional zoning and management of China’s national land space. The results indicate that: (1) during 2000–2020, China’s food supply and soil conservation have increased. However, the habitat quality, water conservation, and carbon sequestration have decreased. (2) Significant spatial and temporal heterogeneities exist in the key ecosystem services of China’s terrestrial ecosystems. (3) Natural, economic, and social factors all impact China’s terrestrial key ecosystem services. Among them, slope, annual average precipitation, land development intensity, and vegetation coverage are the main influencing factors, and different factors exhibit significant spatial heterogeneity. (4) Significant trade-offs/synergy effects among critical terrestrial ecosystem services exist in China. (5) China’s national territory is divided into four ecological protection functional zones: ecological restoration areas, ecological control areas, resilient development areas, and ecological conservation areas, and explores differentiated zoning optimization control paths.

2000-2020 年中国陆地关键生态系统服务的时空特征：权衡协同作用、驱动机制和功能分区

识别生态系统服务功能，厘清陆地生态系统服务的时空权衡与协同效应及其驱动机制，探索差异化生态功能区划，是实现区域生态系统健康管理的关键步骤，有利于制定多元化生态修复战略，建立健全跨区域协同管理机制，实施差异化生态管理策略，促进美丽中国建设。本文基于 InVEST 模型、Pearson 相关性、GeoDetector 和时空地理加权回归模型，构建了 2000-2020 年中国陆地生态系统五大生态系统服务功能--栖息地质量、水土保持、水源涵养、食物供给和碳封存之间权衡与协同的空间量化模型。该研究探讨了中国陆地生态系统服务功能的影响因素及其时空异质性，从而研究了未来中国国土空间生态功能区划和管理策略。研究结果表明(1) 2000-2020 年间，中国的粮食供给量和水土保持量有所增加。然而，栖息地质量、水源保护和碳汇却有所下降。(2）中国陆地生态系统的主要生态系统服务存在显著的时空异质性。(3) 自然、经济和社会因素都会影响中国陆地关键生态系统服务功能。其中，坡度、年平均降水量、土地开发强度和植被覆盖度是主要的影响因素，不同因素在空间上表现出显著的异质性。(4) 中国关键陆地生态系统服务之间存在显著的权衡/协同效应。(5）中国国土划分为生态修复区、生态控制区、恢复发展区和生态保育区四个生态保护功能区，并探索差异化分区优化控制路径。

期刊介绍： Frontiers in Ecology and Evolution publishes rigorously peer-reviewed research across fundamental and applied sciences, to provide ecological and evolutionary insights into our natural and anthropogenic world, and how it should best be managed. Field Chief Editor Mark A. Elgar at the University of Melbourne is supported by an outstanding Editorial Board of international researchers. This multidisciplinary open-access journal is at the forefront of disseminating and communicating scientific knowledge and impactful discoveries to researchers, academics and the public worldwide. Eminent biologist and theist Theodosius Dobzhansky’s astute observation that “Nothing in biology makes sense except in the light of evolution” has arguably even broader relevance now than when it was first penned in The American Biology Teacher in 1973. One could similarly argue that not much in evolution makes sense without recourse to ecological concepts: understanding diversity — from microbial adaptations to species assemblages — requires insights from both ecological and evolutionary disciplines. Nowadays, technological developments from other fields allow us to address unprecedented ecological and evolutionary questions of astonishing detail, impressive breadth and compelling inference. The specialty sections of Frontiers in Ecology and Evolution will publish, under a single platform, contemporary, rigorous research, reviews, opinions, and commentaries that cover the spectrum of ecological and evolutionary inquiry, both fundamental and applied. Articles are peer-reviewed according to the Frontiers review guidelines, which evaluate manuscripts on objective editorial criteria. Through this unique, Frontiers platform for open-access publishing and research networking, Frontiers in Ecology and Evolution aims to provide colleagues and the broader community with ecological and evolutionary insights into our natural and anthropogenic world, and how it might best be managed.
