宜蘭線丸山遺址內部空間配置初探：地理資訊系統的運用

Intra-site Spatial Analysis of the Wansan Site, Yilan Country: The Application of the Geographic Information System (GIS)

本文運用地理資訊系統（Geographic Information System）來分析宜蘭縣新石器時代丸山遺址所出土的各種現象及遺物分佈，尤其希望透過柱洞在遺址內部及其與遺物分布間的關係，尋找房舍建築可能的位置，嘗試探討古代聚落內空間配置的模式，進而提供我們分析古代丸山人群日常生活的基礎。在本研究中，筆者透過三個分析步驟，試圖推測丸山遺址內房舍建築可能的分布地點。首先，透過初步的地圖判讀，嘗試分辨出這些柱洞是否構成空間上可分割的柱洞群；第二步則是進一步套疊上墓葬及遺物的分佈，依此確認這些柱洞群間可能的特性、差異與空間關係；最後則是運用兩種空間統計的方法，嘗試找出這些依賴視覺上辨認出的房舍單位是否具有統計上的意義。

This paper aims to analyze the distribution of features and artifacts uncovered from the Wansan Site in Yilan County by using the Geographic Information System (GIS), particularly focusing on searching for possible house locations through assessing the relationships between the postholes and artifacts. We attempt to explore intra-site spatial patterns in order to set up a foundation for further understanding the Wansan people's daily life.Three steps are proposed to explore possible locations of the houses. First, we inspect whether the postholes form any visually recognizable groups on maps. Second, we explore the characteristics, differences and spatial relations of these visually recognizable groups by overlaying different maps of burials and artifacts. Last, we use two spatial statistical methods to test whether these posthole groups are also statistically significant.
