The development of integrated physical geography at Peking University can be traced back to 1952, when the national department adjustment was taken and the Department of Physical Geography was set up at Peking University. Over the course of more than half a century, a discipline system of integrated physical geography has been gradually formed facing the disciplinary frontier and national needs. In view of the increasingly severe problems related with climate change, natural resources, eco- environment and socio- economic development, integrated physical geography of Peking University has made great progress in land surface process and mechanism, land use/cover change and its eco- environmental effects, ecosystem services and human well- beings, ecological risk assessment and security pattern construction, and physical geographical division, taking a leading role in the development of China's integrated physical geography. Looking forward to the future, the integrated physical geography of Peking University will continue to focus on the mechanism of pattern and process of water, soil, climate and biology, the effects of human activities and global environmental changes on natural geographical process and pattern, quantitative assessment of factors and processes coupled with the regional resources and eco- environmental effects and associated socio- economic impact, constructing a fusion system through coupling observation data and land surface model, so as to make contributions to national strategy such as construction of ecological civilization, main function- oriented zoning, territorial development, and integrated watershed management.
