Urban comprehensive parks carry multiple cultural services and are indispensable to public life and urban functions. Quantitative evaluation of cultural ecosystem services (CES) can provide an effective way to optimize the configuration, planning and management of integrated urban comprehensive parks. Taking Jinan Quancheng Park as an example, we used questionnaires and semi-structured interviews combined with Public participatory geographic information system (PPGIS) to collect research data, and quantitatively assessed the spatial distribution characteristics of ecosystem cultural services values in the park through kernel density analysis, correlation analysis, and multiple spatial eco-index analysis. The results show that: Jinan Quancheng Park has correlation among CES types, and there is correspondence between the park's own characteristics and the value of the same type of CES. The spatial distribution of the park's recreational service value is broader, covering most of the park's area, and it is more concentrated in the southwestern area of the park where the park's recreational function is prominent. The area of higher value of diversity is mainly located in the eastern part of the park where the variety of cultural services is high. The area of higher value of rarity is located in the the center area of the park where single cultural functions are scarce. Through the comprehensive analysis of spatial ecological index, the ecosystem cultural services priority areas for urban comprehensive parks can be more accurately classified for upgrading and management. It can be seen that the quantitative ecosystem cultural service assessment based on the public participatory geographic information system can provide an important basis for the construction and management of urban comprehensive parks in the context of urban renewal.
