本文旨在描述臺東縱谷中，以新武呂溪沖積扇北扇為主體的池上平原文化景觀的空間過程。首先，將其分為：1.史前景觀 2.初墾時期景觀 3.殖民時期景觀 4.民墾兵墾時期景觀。池上平原歷經大約一百年的時間，完成了整個土地拓墾的工作。 其次，本文以土地條件、社群互動和國家政策三個角度，討論上述文化景觀的空間過程，並嘗試建立沖積扇的空間發展模式，依序為史前模式、初墾模式、殖民模式和後殖民模式。透過本文所建立的模式，一方面可作為未來推論臺東縱谷文化景觀變遷模式的參照，另一方面可作為一系列關於池上平原研究的基礎。

This paper aims to discuss the process the process of spatial construction of the cultural landscape in the Chyr-Shan Plain of Eastern Taiwan. In this article, we've tried to distinguish several different characteristics of the land development in the Chyr-Shan Plain during the past 100 years. Thus the process could be divided as the four phases below: 1) Prehistoric Landscape, 2) Micro-reclaiming Landscape, 3) Colonial Administering Landscape, 4) Mass-migrating Landscape. We attempt to analyze these characters of different phases through the dimensions of the land condition, the interaction among local communities and the State policy. We hope that the suggesting models in this essay could become a reference for the following study on the Chyr-Shan Plain.
