Social Value Assessment of Ecosystem Services in Urban Cultural Landscapes from the Perspective of Visitors

The cultural services of urban cultural landscape ecosystems are easily perceived by visitors, and their quantitative assessment and exploration of influencing factors can provide a scientific basis for the optimization of urban cultural landscapes. Existing studies rarely reveal the spatial distribution of the social values of urban cultural landscape ecosystem cultural services and the influencing factors of this spatial distribution from the visitors’ perspective. To reveal the spatial distribution pattern of the social values of urban cultural landscape ecosystem cultural services from the visitors’ perspective, explore its influencing factors, and verify the applicability of the SolVES model in urban cultural landscapes, this study obtained the overall perception and preferences of visitors towards Cangzhou Garden Expo Park through a questionnaire survey. Combining the questionnaire survey data with geographical data, the SolVES 3.0 model was employed to conduct quantitative assessments and spatial distribution analyses of six social values of the ecosystem: esthetic, biodiversity, historical, recreation, learning, and life-sustaining values. The following conclusions were drawn: (1) The maximum value index of recreation value and esthetic value were highest, and showed significant spatial concentrated characteristics, with hotspots concentrated at the northeast side of the park. (2) Biodiversity value and historical value were prominent near areas rich in plant resources and industrial heritage sites. (3) The distance to roads and slope significantly influenced the assessment of social values; social values showed a significant negative correlation with distance to roads. (4) The Garden Expo Park had strong advantages in ecological restoration and social value supply, but there were still problems such as inconvenient transportation and uneven value distribution. Based on the above results, this study proposed suggestions for enhancing the social values of the ecosystem services in Cangzhou Garden Expo Park, and further provided targeted optimization suggestions for the construction and management of urban cultural landscapes. The SolVES model showed good performance in assessing the social values of the ecosystem services of an urban cultural landscape, with high reliability and promising application prospects.
