在总结地貌学传统基本理论并结合现代地貌学研究成果的基础上,提出了地貌含义的新的理解和地貌系统的整体观。地貌是由形态、组成物质、作用过程和边界条件4个组成部分互相依存、互相作用,并要求相互适应而构成的整体。这一新的地貌含义加入了形态和边界条件两个因素,从而不同于传统的“地貌是构造、营力和时间的函数”的表达模式。建议“时间”可以不作为影响地貌发育的因素,这样就为“地貌是三维空间和时间组成的四维空间的总体”这一说法赋予了新的含义。还提出地貌的发展演变是地貌各组成部分不能相互适应而出现的“非平衡态”过程,时间并不是地貌发展演变的动力。自然界处于“平衡态”的地貌是存在的,自然界地貌各组成部分总是具有一定程度的相互适应,因而总是具有一定的稳定性,这也是现代地貌学能够进行定量研究的基础。边界条件是控制地貌发育的关键因素,地貌发展演变的方向是由地貌的初始状态（形态）和边界条件决定的。

〖BFQ〗〖JZ)〗〖HJ1*2〗〖HJ〗〖WTHZ〗Abstract：〖WTBZ〗 This paper mainly discusses the recognition and development of basic ideas of modern geomorphology. Based on the summary of traditional geomorphology theory and research achievements in modern geomorphology, it puts forward a new explanation on the meaning of landform and integral view of geomorphic system. Landform is an interrelated and co adapted entirety, composed of morphology, composition materials, geomorphic process and boundary conditions. This new interpretation of landform is different from the traditional genetic mode, which regards landform as a function of geologic structure, agent and time.This paper does not suggest that time as a factor of geomorphic evolution, then, it can provide a new understanding on the statement that landform is a complex of four dimensional space which consists of three dimensional space and time. In this study, geomorphic evolution is a “non equilibrium state” process, which is caused by the maladjustment among the four geomorphic elements, and time is not the drive power of geomorphic evolution. The “geomorphic equilibrium state” does exist in nature, which is also the basis of quantitative research in modern geomorphology. Boundary conditions are critical factors that control the geomorphic evolution process, and geomorphic evolution direction is decided by original geomorphic features and boundary conditions.
