Parks have become important spaces for supplying cultural ecosystem services (CESs) in cities, and satisfying various needs of different age groups in parks has become a critical issue. Many studies focused on the environmental preferences and behaviours of different age groups in parks. However, results revealing the differences in value demand and acquisition between elderly and youth from a landscape spatial environmental perspective are limited. In this study, the same number of youth and elderly volunteers were recruited, according to the value-labelled photo fed back after their self-driven tour in the Huanhuaxi Urban Forest Park in Chengdu, China. In addition, this study explored the relationship between the perceived CES needs of the youth and elderly and the landscape spatial environment in the urban park ecosystem with the help of the Social Values for Ecosystem Services model. Results showed that, in comparison, to obtain recreation value, playgrounds, pavilions and squares were more important for the elderly, whereas topography, rivers, landscape sketches and trails were more important for the youth. Moreover, in terms of the sense of place, lakes and wetlands were more important for the elderly, whereas landscape sketches and playgrounds were more important for the youth. Furthermore, for the delivery of therapeutic value, squares were more important for the elderly. Spatially, the areas of lakes or wetlands with geographical combinations of landscape sketches and flowers were the high-value spots for supplying multiple CESs in urban parks. Then, squares, rivers, playgrounds and forests were the focus areas where the value identification of the two age groups diverges. This study emphasises the differences in demand and acquisition of cultural added value provided by the environment between the young and the old. The study provides a basis for more targeted land management and landscape planning of urban parks.
