摘要

准确识别生态补偿区域，建立明确的补偿标准，对促进碳固存、缓解生态退化、支持资源公平配置具有重要意义。我们引入了比较生态辐射力（CERF）的概念来描述生态环境的空间流动，并估计平衡这些流动所需的总补偿。结果表明，以净初级生产（NPP）为代表的碳固存价值达到1.21 × 10⁶CNY，与其他关键服务如土壤保持（SC）（284.69 × 106 CNY）、产水（WY）（44.99 × 106 CNY）和食物供应（FS）（20.81 × 106 CNY）并列。服务流的方向性分析表明，NPP、SC和WY以东向西为主，而FS则以北向南为主。值得注意的是，NPP仅占总生态补偿的0.16%，而SC为95.42%，WY为4.21%，FS为0.21%。本研究提供了一个统一的框架，使EC战略与碳管理目标保持一致，为支持TP上的碳中和努力和生态系统恢复提供了见解。

Reconciling ecosystem service supply-demand mismatches through ecological compensation in the Tibetan plateau

Accurately identifying ecological compensation (EC) regions and establishing clear compensation criteria are essential for promoting carbon sequestration, mitigating ecological degradation, and supporting equitable resource allocation. In this study, ecological modeling combined with hotspot analysis was applied to quantify the spatial mismatch between ecosystem service (ES) supply and demand on the Tibetan Plateau (TP) in 2020. We introduced the concept of comparative ecological radiation force (CERF) to characterize the spatial flow of ESs and to estimate the total compensation required to balance these flows. Our results highlight that the value of carbon sequestration, represented by net primary production (NPP), reached 1.21 × 10⁶ CNY, alongside other key services such as soil conservation (SC) (284.69 × 10⁶ CNY), water yield (WY) (44.99 × 10⁶ CNY) and food supply (FS) (20.81 × 10⁶ CNY). The directional analysis of service flows revealed that NPP, along with SC and WY, predominantly flowed from east to west, while FS exhibited a north-to-south pattern. Notably, NPP received only 0.16% of the total ecological compensation, in contrast to 95.42% for SC, 4.21% for WY, and 0.21% for FS. This study provides an integrated framework for aligning EC strategies with carbon management goals, offering insights to support carbon neutrality efforts and ecosystem restoration on the TP.

期刊介绍： Carbon Balance and Management is an open access, peer-reviewed online journal that encompasses all aspects of research aimed at developing a comprehensive policy relevant to the understanding of the global carbon cycle. The global carbon cycle involves important couplings between climate, atmospheric CO2 and the terrestrial and oceanic biospheres. The current transformation of the carbon cycle due to changes in climate and atmospheric composition is widely recognized as potentially dangerous for the biosphere and for the well-being of humankind, and therefore monitoring, understanding and predicting the evolution of the carbon cycle in the context of the whole biosphere (both terrestrial and marine) is a challenge to the scientific community. This demands interdisciplinary research and new approaches for studying geographical and temporal distributions of carbon pools and fluxes, control and feedback mechanisms of the carbon-climate system, points of intervention and windows of opportunity for managing the carbon-climate-human system. Carbon Balance and Management is a medium for researchers in the field to convey the results of their research across disciplinary boundaries. Through this dissemination of research, the journal aims to support the work of the Intergovernmental Panel for Climate Change (IPCC) and to provide governmental and non-governmental organizations with instantaneous access to continually emerging knowledge, including paradigm shifts and consensual views.
