The concept of park city provides the basic theoretical guarantee for the construction of urban green space, and also brings new ideas and new challenges for urban ecological space construction and economic construction. Combined with the previous research review, this paper combs and condenses the connotation of park city, explores the extension of the concept of generalized urban green space system in the new era, and clarifies the new ideas and requirements of functional orientation transformation and adjustment as the carrier of park city construction. From the perspective of green based map construction, green space function control mechanism and community integration mode, this paper puts forward the green space construction strategies and approaches under the guidance of park city concept, and constructs the park city life community of “ park city integration”.
