Public activity space within the urban residential green space is the most frequently used space for residents' leisure and entertainment activities, which are substantial in the improvement of the cultural ecosystem services of green spaces and the amelioration of the neighborhood environment and the residents' physical and mental health. Focused on the residents' perception of leisure culture, our study explored the effects of the landsenses ecology on the public space of residential areas. We also revealed the effect of multifunctional green space landscapes on ecosystem cultural services and landsenses creation to provide important directions for the planning and the design of green space in residential areas. This paper selected 80 public activity spaces in 26 residential communities in Zhengzhou as research objects. The following results were obtained. (1) The significant differences were observed in the sense of landscape effect provided by different types of public activity spaces in residential green spaces. The natural attributes of water bodies enriched the sense of landscape effects and had the highest cultural ecosystem service value. (2) A large public green space in the residential area resulted in strong psychological perception of the residents, rich sense of scenery experience, and high value of cultural ecosystem services. Increasing the area of the public activity space was a direct channel to build a multifunctional green space landscape. (3) The ecological effects of the visual sense created by the vegetation coverage and shade rate created by the public event space were significant, but the tactile sense of the infrastructure and the visual sense of cleanliness did not exist. (4) Combining with the social and the economic data of the community, the results of multiple regression analysis showed that the diverse sense of landscape created by the public activity space had the largest contribution to the amount of residents' activities followed by the type of public activity space and the number of households in the community. The theory of landscape ecology and the principles of sense of landscape creation were applied, and the landsenses carrier was achieved through the landscape design in a limited space, thereby improving the green space ecosystem services and alleviating the unfairness of the urban green space. Finally, high-density urban residential areas were suggested to be provided with large public activity spaces with multifunctional characteristics as much as possible, and low-density residential areas were suggested to be provided with large-scale natural water bodies and additional multiple types of public activity paces to enhance the effect of scenery.
