This study addresses the high degree of subjectivity and the supply–demand imbalance in wetland park science communication. Taking the Nanjing Longpao Yangtze River Provincial Wetland Park as a case study, it develops a data-driven, sustainability-oriented design framework integrating NVivo (qualitative data analysis software), the Analytic Hierarchy Process (AHP), the KANO model, Artificial Intelligence Generated Content (AIGC), and Fuzzy Comprehensive Evaluation (FCE) into a closed-loop methodology. A wetland database was constructed through field research and a literature review. User interviews (N = 73) were analysed using NVivo to distill core themes. AHP, based on 15 expert pairwise comparisons, identified Distinctive Plants (global weight 0.314) and Rare Bird Species (0.275) as priority design elements. The KANO model classified 20 science topics into Must-be (N = 5), One-dimensional (N = 2), and Attractive (N = 8) attributes. AIGC was then employed to generate a three-module promotional brochure (wetland flora, avifauna, and culture). FCE with 60 valid respondents confirmed all three modules achieved an ‘Excellent’ rating, validating the framework’s effectiveness. This study provides a replicable, sustainable design paradigm for wetland science communication.

Wetlands support biodiversity and hydrological regulation; bird communities are sensitive indicators of environmental change. However, evidence linking bird-community patterns to restoration remains limited in the lower Yangtze floodplain wetlands. We aimed to characterize bird-community composition and spatiotemporal diversity in Longpao Yangtze Wetland and examine their association with restoration history. We conducted monthly surveys from November 2024 to September 2025 using line transects, point observations, and Unmanned Aerial Vehicle (UAV) monitoring. Combined records described species composition, standardized field records provided diversity indices, and historical records showed interannual patterns. We recorded 197 species in the combined inventory, including 5 Class I and 30 Class II nationally protected species; standardized surveys recorded 144 species. Winter migrants and Palearctic species were the largest residency and zoogeographical groups, respectively. Diversity was highest in spring and lowest in autumn, although autumn included one survey. Heterogeneous transects YX6 and YX3 had higher diversity. Recorded richness increased from 59 species (2019) to 197 (2025), coinciding with restoration. Longpao Wetland supports diverse birds of conservation concern, emphasizing the value of heterogeneous habitats. Unequal seasonal effort and inconsistent historical methods preclude causal inference. Future research should use standardized long-term monitoring and quantitative habitat analyses to guide hydrological management, habitat enhancement, and community co-management.
