Abstract: Evaluating ecosystem services and quantifying the trade-offs and synergies between those services on the bases of the coupled social-ecological system, have theoretical and practical significance for ecosystem services research and national park planning and management. Taking China's Pudacuo National Park as the research site, this article employs the SolVES and InVEST models to construct the coupling coordination degree model between perceived biodiversity value and habitat quality and comprehensively evaluates biodiversity value using Getis Ord G i* to obtain social-ecological hotspots. The results show that:(1) The hotspots of perceived biodiversity value exhibit a "multi-core and multi-strip" spatial pattern, with a significant negative correlation with distance to roads and water bodies, a significant positive correlation with altitude, and its value index reaches its maximum in forest land. (2) The habitat quality index is high in the central, southern, and northeastern regions, low in the western and eastern regions; the high-value areas of habitat quality are found in forest land and grassland in the mountainous areas, while the low-value areas are found in the valley and plain areas. (3) The coupling degree between perceived biodiversity value and habitat quality is at the high-level stage. Their coupling ordination degree is at the middle-level stage of good coordination. The coupling coordination category belongs to the social lag ecotype. (4) Social-ecological hotspots are concentrated in the park's southwest part and forming a "single strip" distribution pattern, and some of the hotspots are distributed in the northeast. In contrast, the social-ecological coldspots are relatively concentrated and mainly located in the lower reaches of Niru River in the east of the park. This study provides a scientific basis for reconstructing the theoretical framework of biodiversity assessment and biodiversity protection, regulation, and management.
