An accurate and real-time database of urban green space resource information is the premise of green land informatization and refined management. Still, it faces the problems of delayed spatial information and lack of green space attribute information, which severely restricts the timeliness and accuracy of green space information management. Based on the analysis of the characteristics of the space and structure of urban green space, this paper proposes a set of practical methods for the construction and maintenance of an integrated information collection of urban green space resources based on GIS. Based on GIS, a group of techniques for acquiring and checking spatial information established, including a method for extracting green information based on remote sensing, a veri cation unit for spatial information approval, approval content, and approval methods, and proposed the construction of an attribute database based on green space classi cation—method  ow, including database  eld design and survey methods. The integrated approach of building and maintaining airspace can provide practical method support for the informatization management of landscaping in various places. It can effectively solve the problem of "deadness" in the use of information management systems caused by the delayed updating of information.
