侧面地貌景观的概念模型研究

A Conceptual Framework for Geomorphologic Landscape Units with a Front-Side Viewpoint

地貌单元的空间格局对地表的物质、能量分配具有决定性影响。针对当今地貌学研究中尚未形成比较系统的从人眼直视的角度(即侧面)研究地貌单元的垂直格局特征的理论与方法,该文分析了侧面的地学含义;从地貌单元在垂直侧面的物质与能量分异角度提出了侧面地貌景观的概念,据此分析了侧面地貌景观的基本内涵并探讨了其主要研究内容;结合前述研究,分析了侧面地貌景观的尺度性、复杂性和系统性特征。在前期实验研究的基础上,初步提出了侧面地貌景观量化分析的基本思路与技术方案。研究工作对于人们进一步深化对地貌的科学认识具有一定的参考意义,但相关理论观点和方法有待进一步的实践检验。

A geomorphologic landscape unit owns its only physical attributes, geometric morphological features and boandary. The distribution pattern of landforms plays the hegemonic role on the materials and energy of the earth＇s surface. The1 efore, it is an important topic for comprehensive understanding the human-land relationship that we further know about the scientific connotation of landforms. De facto, there does still not form a systematic method for vertical pattern of geomorphologic land- scape unit with a front-side viewpoint. This maybe hinders the human to further capture the geomorphologic landscaps units. The goal of this work is to set up a conceptual framework for understanding the geomorphologic landscape units with a perspec- tive of front-side viewpoint. This paper firstly puts forward to a new concept about front-side viewpoint geomorpholosic land- scape according to the vertical feature methodology of landscape ecology. With the aforementioned theoretical foundat on, this paper analyzes the base connotation and defines a conceptual framework for front-side viewpoint geomorphologic landscape. In fact, this conceptual framework is composed of pattern analytical framework and its feature analytical indices. From this paper, there are three key features of front-side viewpoint geomorphologic landscape. They are scale, complexity and systematic, respectively. At last, this paper can provide a new sight for human to understand the real geomorphologie landscape units.
