Abstract: Scientific identification of ecological space is the basis for promoting the modernization of land space governance system and governance capacity. We used literature review, inductive summarization and comparative analysis to clarify the concept of ecological space identification. We reviewed recent technological advancements and further defined the innovative pathways and directions for future research. China’s ecological space identification techniques primarily consisted of multisource data overlay analysis, ecological space evaluation, integration of the InVEST model with related spatial analysis methods, habitat identification for endangered species or nature reserves, and dynamic ecological space identification, with steady progress in their development and refinement. These techniques varied in scale, data requirements, research paradigms, and objectives, each possessing distinct advantages and limitations. Accordingly, we delineated the technical approaches with complete flow scheme for identifying ecological protection gaps by comprehensively applying various ecological space identification systems at multiple scales, complementing each other. Future research should focus on three key aspects: developing a comprehensive and multidimensional ecological space identification technology tailored to local conditions, fostering technological integration and interdisciplinary collaboration, and enhancing international cooperation and localized innovation.
