Examining the supply-demand relationship of rural cultural ecosystem services at a micro scale enables villages to precisely enhance cultural service provision, which is of great significance in solving the problem of mismatch of resources in villages and promoting the high-quality development of villages. Taking Lian Village in Fujian Province as the research object, this study uses a Public Participation Geographic Information System (PPGIS) to quantify cultural ecosystem services at a micro scale. Additionally, a supply and demand evaluation index system for rural cultural ecosystem services was established. The coupling coordination index and spatial autocorrelation analysis were conducted, ultimately determining the spatial matching characteristics of the supply and demand of cultural services in Lian Village. The results show that: (1) Of the three cultural service types in Lian Village, leisure and recreation is most highly rated, followed by aesthetics, while science and cultural services are the least favored. Spatially, the distribution of leisure and recreation and aesthetic services mirrors each other, predominantly high in the vicinity of the ancient banyan tree and streamside, whereas science and culture services are notably concentrated around the ancestral temple and the statue of Xue Lingzhi. (2) The supply areas of cultural services are concentrated in the Lian Village settlement and its surrounding areas, with the strongest supply capacity at the eastern wall entrances and southern wall entrances. The demand areas are relatively dispersed, with the highest demand at the main entrance of Lian Village. High-demand points also appear in the northern residential area within the settlement, the ancient official road, the self-service tea house, and the sandbank. (3) The overall supply-demand coupling and coordination showed two aspects: the settlement and its surrounding areas were well-coordinated, while the peripheral areas of villages exhibited a slight mismatch. Among these, the near-imbalanced areas account for 54.69%, mildly imbalanced areas account for 27.03%, and coordinated areas account for 18.28%. (4) Based on the supply-demand match results, Lian Village was categorized into cultural service performance good area, key improvement area, additional potential area, and slow improvement area. Priority should be given to allocating resources to key improvement areas, specifically the southeastern sandbank area and the northern entrance of the settlement, to optimize resource efficiency and maximize benefits. Overall, there are different degrees of mismatches between the supply and demand of cultural services in the internal space of Lian Village, and based on the assessment results, we provide corresponding recommendations for Lian Village to accurately improve the level of cultural services.
