Abstract

Qilian Mountain National Park (QMNP) is a critical ecological barrier and water conservation area in northwestern China. Its diverse ecosystems provide significant ecosystem services, yet the valuation of these services and their dynamic responses to land use/cover (LULC) changes and ecological protection measures require detailed investigation. This study employs an improved equivalent factor method, tailored to the specific ecosystem types and LULC patterns of QMNP, to evaluate the ecosystem service value (ESV) across different LULC types. Using an elasticity analysis model, the sensitivity of ESV to LULC changes from 1990 to 2022 was quantitatively assessed. The results indicate that the ESV of QMNP increased from 46.13 billion RMB to 50.97 billion RMB between 1990 and 2022, mostly due to the growth of grassland and forest areas. The primary route for increasing the region’s ESV is the conversion of desert to grassland, and this should be a major area of emphasis for next ecological conservation initiatives. Regulating services form the core of the ESV in QMNP, with climate and hydrological regulation contributing significantly to the overall ESV. Maintaining the stability of forest, wetland, and water body areas is crucial for sustaining the total ESV of QMNP. Through the application of carbon emission coefficients and ESV methods, the average range for long-term ecological compensation standards in QMNP is expected to be between 3.78 billion RMB and 28.28 billion RMB annually. Additionally, we explore the impacts of ongoing ecological protection mechanisms on enhancing ESV. There is a pressing need to formulate integrated policy frameworks that balance ecological conservation with sustainable economic development. The study also highlights the necessity of strengthening the protection and foundational research of grasslands and water bodies to enhance the ESV of QMNP. These insights serve as a foundation for potential planning and management strategies in QMNP, aiming to maintain and enhance its ecosystem functions and services, thereby contributing to broader regional and global ecological stability.

祁连山国家公园生态系统服务价值与生态补偿：对生态保护战略的影响

祁连山国家公园（QMNP）是中国西北部重要的生态屏障和水源保护区。其多样化的生态系统提供了重要的生态系统服务，然而这些服务的估值及其对土地利用/覆盖（LULC）变化和生态保护措施的动态响应需要详细的调查。本研究针对祁连山国家级自然保护区特定的生态系统类型和 LULC 模式，采用改进的等效因子法评估不同 LULC 类型的生态系统服务价值 (ESV)。利用弹性分析模型，定量评估了 1990 年至 2022 年期间 ESV 对 LULC 变化的敏感性。结果表明，从 1990 年到 2022 年，青铜峡国家级自然保护区的 ESV 从 461.3 亿元增加到 509.7 亿元，这主要归功于草地和森林面积的增长。增加该地区 ESV 的主要途径是将荒漠转化为草地，这应成为下一步生态保护措施的重点领域。调节服务是青铜峡国家自然保护区 ESV 的核心，其中气候和水文调节对总体 ESV 有重大贡献。保持森林、湿地和水体区域的稳定对于维持青铜峡国家公园的总 ESV 至关重要。通过应用碳排放系数和 ESV 方法，预计秦巴山区国家级自然保护区长期生态补偿标准的平均范围为每年 37.8 亿元人民币至 282.8 亿元人民币。此外，我们还探讨了现行生态保护机制对提高 ESV 的影响。目前迫切需要制定综合政策框架，以平衡生态保护与可持续经济发展。本研究还强调了加强草原和水体保护及基础研究以提高钦州保山国家公园 ESV 的必要性。这些见解为青铜峡国家公园潜在的规划和管理策略奠定了基础，旨在维护和增强其生态系统功能和服务，从而为更广泛的区域和全球生态稳定性做出贡献。

期刊介绍： The ultimate aim of Ecological Indicators is to integrate the monitoring and assessment of ecological and environmental indicators with management practices. The journal provides a forum for the discussion of the applied scientific development and review of traditional indicator approaches as well as for theoretical, modelling and quantitative applications such as index development. Research into the following areas will be published. • All aspects of ecological and environmental indicators and indices. • New indicators, and new approaches and methods for indicator development, testing and use. • Development and modelling of indices, e.g. application of indicator suites across multiple scales and resources. • Analysis and research of resource, system- and scale-specific indicators. • Methods for integration of social and other valuation metrics for the production of scientifically rigorous and politically-relevant assessments using indicator-based monitoring and assessment programs. • How research indicators can be transformed into direct application for management purposes. • Broader assessment objectives and methods, e.g. biodiversity, biological integrity, and sustainability, through the use of indicators. • Resource-specific indicators such as landscape, agroecosystems, forests, wetlands, etc.
