As an interdisciplinary field integrating soil science and geography, soil geography has increasingly demonstrated significant academic and practical value in areas such as global environmental change, sustainable land use, and ecosystem management. This paper provides a systematic overview of the core research themes and recent advances in soil geography, with particular emphasis on the mechanisms of soil formation and evolution under extreme environmental conditions, the impacts of land use change on soil properties and spatial heterogeneity, and the innovative applications of digital soil mapping and intelligent modeling technologies. In the face of global challenges such as climate change, land degradation, imbalances in biogeochemical cycles, and the decline of ecosystem services, accurately identifying soil characteristics and their spatial variability has become essential for advancing sustainable agriculture, ecological restoration, carbon sequestration, and the efficient management of land resources. This paper aims to explore the current research landscape and emerging trends in soil geography, identify key scientific questions that require urgent attention, and provide theoretical support and decision-making references for the sustainable use of soil resources and the maintenance of ecosystem stability in the context of global change.
