「五行」這一玄學名詞，原義為夏代之「五行列式灌溉渠」地理環境，在周人創立五因子式井田制度時所沿用，但因至東周時代，井田制度已廢用甚久，五行為灌溉系統之原義已夫，「五行空間概念」乃被玄化。本文提供資料，闡釋五行空間概念的起源與演化，又論述其對五行地理景觀之關係，為一歷史地理學之研究也。

　　　　　The term "Five Elements" is diverted from "Five-strip lrrigation System" in Hsia Dynasty. The spatial distribution patterns of Five Elements changed from five strips to five elemental cells in Eastern Chou Dynasty.

This article is to provide information and explanation on the linkage between well-field and the spatial concept of five elements. In addition, "Five Element landscape' is served to remove the metaphysical cover of Five Elements from "geographic" point of view.
