Abstract: In response to the urgent demand of the national “language resources protection and development” and the development trend of scientific and technological integration, this paper formally proposes the emerging field of “linguistic-spatial intelligence”. This field integrates linguistics, geography and artificial intelligence, and focuses on information recognition, extraction, processing, reconstruction, mapping, mining analysis and intelligent service of multimodal linguistic data. The paper firstly clarifies the basic connotation of linguistic-spatial intelligence, covering aspects such as its concept, internal logic, application domains, and core scientific issues. Secondly, it refines several core research contents in this field and introduces its supporting theories and methods. Finally, the opportunities and challenges faced by this field are clarified, and the path of its realization is discussed. This research will not only help to promote the construction of cross-disciplines and the identification of academic growth points, but also provide important guidance for the cultivation of innovative talents and cutting-edge social applications, as well as help the protection and development of language resources.
