Cultural ecosystem services (CESs) play a critical role in urban residents’ well-being, yet conventional evaluations rely heavily on green-space area and overlook how facility quality and basic services influence the delivery of actual cultural benefits. To address this methodological gap, this study develops a three-tier evaluation framework—service potential, actual supply capacity, and actual service utility—to quantify multistage attenuation in CES provision across 95 parks in seven central districts of Shenyang, China. The framework integrates 114 quantitative and qualitative indicators from field surveys, national facility standards, and perception-based assessments, enabling a scientifically robust and replicable assessment of how cultural benefits are transformed from ecological structure to human experience. Results reveal that single-index, area-based assessments substantially overestimate CES supply: district-level supply–demand ratios drop from 66 to 195% to only 11–55% once quality and basic services are incorporated. Comprehensive and special parks retain the highest CES potential, whereas community and linear parks undergo significant losses due to aging facilities, insufficient maintenance, and inadequate infrastructure. Education and cultural services exhibit the most severe shortages, with deficits reaching 59–84%, underscoring structural limitations in learning-oriented spaces. By distinguishing structural (quantity), functional (quality), and experiential (basic service) constraints, the framework provides clear diagnostic guidance for targeted planning and management. Its multistage structure also reflects broader principles of sustainable urban development: improving CES requires not only expanding ecological elements but also enhancing service quality, strengthening infrastructure, and promoting equitable access to cultural benefits. The framework’s generalizability makes it applicable to high-density cities worldwide facing land scarcity and green-space inequality, supporting efforts aligned with SDG 11 to build inclusive, resilient, and culturally vibrant urban environments.
