摘要：Scientifically evaluating the ecosystem service value (ESV) of national parks and understanding the trade-offs and synergies between different ecosystem services is crucial for advancing the establishment of China’s national park system. This study focuses on the Qianjiangyuan National Park pilot area, utilizing land use data from 1990-2020. The evolution of ESV in the pilot area is investigated by applying the equivalent value method. An ecosystem service trade-off/synergy model and spatial autocorrelation analysis are further utilized to measure the complex relationships and spatial distribution characteristics between ecosystem services. The total ESVs in 1990, 2000, 2010, 2015 and 2020 were found to be CNY 170.63×107, CNY 169.65×107, CNY 171.89×107, CNY 171.95×107, and CNY 172.11×107, respectively. The overall change was minimal, exhibiting an increasing trend. Forest land was the main contributor to ESV, followed by farmland and grassland. Regulating services, particularly gas regulation, climate regulation, and water regulation, exhibited the highest contribution rate. Economic factors emerged as the primary contributors to national park ESV. Factors like crop sowing area, birth rate, newborn population, grain yield, rural population, and rural Engel coefficient were negatively correlated with ESV; tea yield showed no correlation with ESV. From 1990-2020, the relationships between individual ecosystem services in the national park pilot area were mainly synergistic. There was a trade-off between food production services and other services during 2000-2010 and 2010-2015, which diminished from 2015 to 2020, with trade-offs remaining only for hydrological regulation, waste treatment, and landscape aesthetics services. The sensitivity analysis indicated that the coefficient of sensitivity (CS) values for different periods were all less than 1, indicating that the calculated ecosystem service value coefficients based on the revised equivalent factor table conform to the actual conditions of the national park pilot area. There were positive spatial autocorrelations for ESVs in the national park pilot area, indicating a clustered distribution pattern. High-value clusters were mainly identified in Suzhuang Town and Qixi Town. Low-value clusters were predominantly found in marginal areas, particularly near the community border. The results of this work may offer meaningful theoretical and practical guidance for national park ecosystem management. ? 2024, The Authors. All rights reserved.
