ABSTRACT: Landscape pattern changes are one of the main reasons affecting the supply and maintenance of ecosystem services, and they also form the basis for the management of ecosystem services and the optimization of landscape spatial configuration. Clarifying the impact of landscape pattern changes on ecosystem services is of significant theoretical and practical importance for the protection of the ecological environment and the scientific management of ecosystems. This paper selects four important ecosystem services: soil conservation, water conservation, habitat quality, and net primary productivity. By using the InVEST and CASA models, it quantitatively assesses the characteristics of changes in ecosystem services in the Minshan area of the Giant Panda National Park from 2000 to 2020 and explores the response of ecosystem services to changes in the landscape pattern. The results indicate that: 1) From 2000 to 2020, the dominant landscapes were forests and grasslands, with land types mainly converting between forests, grasslands, and cultivated land. The forest area increased from 5220.42 km2 to 5297.56 km2, while the grassland area decreased from 4414.82 km2 to 4339.46 km2. 2) From 2000 to 2020, net primary productivity showed a “U” shape change; soil conservation increased from 6.73 × 109 t to 8.66 × 109 t, and water conservation increased by 10.06%, indicating an overall improvement in the level of ecosystem services in the Minshan area of the Giant Panda National Park. 3) Different ecosystem services respond significantly differently to the landscape pattern, and the spatial heterogeneity characteristics are evident. Habitat quality is significantly positively correlated with the aggregation index and the largest patch index, while net primary productivity is significantly negatively correlated with these two indices. The research results are beneficial for adjusting the landscape pattern optimization of the Giant Panda National Park and for formulating ecological environment governance and protection measures tailored to local conditions.
