The urban green space system can not only effectively improve the ecological environment of urban clusters, but also promote the sustainable and recyclable development of modern cities. Therefore, a scientifically arranged urban spatial structure is the key to give full play to the ecological functions of green spaces, and it is necessary to build a new framework for green space construction needs under the arrangement pattern of the landscape pattern. This study takes GIS as the technical research object, and uses geospatial database as the basis to create a new urban green space model at the planning and design level, allowing resource information to be accurately quantified and promoting the ecology of urban development.
