The rise of integrated physical geography in China is not an accidental event. It was closely connected with the construction of the related theory system, the fostering of domestic professional scholars, the inheritance of academic history both at home and abroad, and the demand of social development in China. Specifically speaking, it was influenced by the spread of Western modern geography in the early 20 th century, and the traditional harmony theory of Chinese ancient geography; it was also associated with the geographical intensive Sino-Soviet academic communications in the 1950 s, as well as the needs of economic development in China. All in all, as a branch of physical geography, the integrated physical geography is a practice-oriented subject, focusing on comprehensive perspectives of natural regionalization,land change, and landscape service. The main contents of integrated physical geography studies in China have developed from agricultural regionalization and ecological regionalization to integrated regionalization; from land type, land source to land system; from landscape pattern research to landscape function and service research. Along with the change of the study theme,this subject kept on improving and deepening. Faced with the growing challenges such as rapid urban expansion, serious environmental pollution, and the natural resource exhaustion, the integrated physical geography in China is trying to explore new integrated approaches in accordance with the transformation of the time background. It chooses coupled human and natural systems as its study object, considers the synthesis of processes interaction at different regional scales, makes landscape sustainability as its key research field, and uses big data and high technology as its methodology.
