Cultural ecosystem services (CES) are important parts of ecosystem services and are receiving increasing attention. As the ecological barriers in the northern China, Xilin Gol League has witnessed more serious degradation in recent years. A large number of ecological restoration projects (ERPs) have been carried out in Xilin Gol, among which, grazing prohibition, rest grazing, grass-animal balance are the most representative ones. In this study, we used the questionnaire survey method to investigate the perceptions of 144 respondents in Xilin Gol on the CES of grassland ecosystem, and analyzed the factors influencing these perceptions. In addition, we compared the CES of grassland in three ERPs areas ("rest grazing", "rest grazing +grass-animal balance", "rest grazing + grass-animal balance + grazing prohibition"). The results showed that: (1) Respondent's perception of grassland's CES was affected by their ethnicity, age and education level (P<0.05), the perception of Mongolian people on mental and physical health, and the aesthetic services is higher than that of Han ethnic groups; the older group has higher perception than the younger one on mental and physical health, education and science, and low perception on recreational services; the group with high education level has higher perception on education and science services. (2) ERPs affected the CES of grassland, several grassland's CES (mental and physical health, inspiration, spiritual and religious services, sense of place, recreational services) in "rest grazing + grass-animal balance + grazing prohibition" region is lower than that of the other two areas.
