Emergence of the physical geography oriented palaeogeography started the physical geography in time perspective, which has been extended from palaeogeography into environment change during its development in China. The regional tradition of geography based palaeogeography focuses on the construction of modern natural environment by reconstructing the history of the regional environment. The earth science tradition of geography based environment change focuses on the characteristics and mechanisms of the earth system from the clue of time. In addition, the manenvironment tradition based on manenvironment system change is the third aspect of the physical geography in time perspective. In broad sense, manenvironment system change may be regarded as the environment change which includes the human factor as a driving force and the objects impacted by environment change. If palaeogeography is defined by the manenvironment relation, instead of environment, it is a science on the manenvironment system change.
