Geography is a comprehensive discipline that spans the natural sciences, social sciences, and technical sciences. Integration is the essence and soul of geography. Geography’s initial comprehensiveness stemmed from its diversity; however, with the deepening development of its subfields, geography has increasingly become hollowed out. To prevent this, it is essential to strengthen foundational research in geographic theory and methods, enhance the study of human-natural interactions and their coupling mechanisms, and emphasize the integrated essence of geography.
