Establishing an intelligent territorial spatial planning layout for big data is conducive to addressing the shortcomings and defects in the development and utilization of big data. With the help of intelligent theories and innovative concepts, it promotes the deep integration of national spatial planning, policies and systems, and scientific research and technology, and improves the level of intelligent national spatial planning in the context of ecological civilization. This article takes smart land spatial planning as the research object, and big data intelligent information technology as the support, it explores the solutions to the problems and related optimization strategies in current land spatial planning, and puts forward suggestions for the application of information intelligence technology in land spatial planning.
