时间维的自然地理学研究

自然地理学方向的古地理学开创了时间维地理学研究的领域,其在我国的发展经历了一个从古地理学向环境演变研究拓展的过程。以现代自然环境的历史建构为主体的古地理学,以时间坐标系下自然地理过程研究为主的环境演变研究,以从时间的维度探索人地关系为主的人地系统演变研究,分别体现了地理学的区域研究传统、地球科学传统和人地关系传统，构成了自然地理学时间维研究的3个基本方面。广义地理解自然地理学方向的古地理学、环境演变以及人地系统演变,它们可以看作是相通的,人地系统演变可以理解为包括了人类作为驱动力和承受者的环境演变,用人地关系来定义自然学地理方向的古地理学,则可以将其定义为关于人地（人类-环境）系统历史演变的科学。

Physical geography in time perspective

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 man-environment tradition based on man-environment system change is the third aspect of the physical geography in time perspective. In broad sense, man-environment 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 man-environment relation, instead of environment, it is a science on the man-environment system change.
