空載光達技術在台灣山區舊社考古學研究的應用：以排灣族文樂舊社為例

An Application of Airborne LiDAR to the Archaeological Study of Abandoned Indigenous Settlements in Mountain Areas - A Case Study of the Wun-lou Site of the Paiwan Group, Taiwan

研究位於山區的原住民舊聚落，往往會受限於山地的困難地形與茂密植被。有許多舊社位於無路徑或未知之處，幾乎無法以徒步調查的方式取得這些舊聚落的分布。而已知的山區舊社，也因植被覆蓋，以致紀錄於地表上的石砌結構時，需要先以大量人力將低層的植被清除，才得以窺其全貌。本研究將空載光達技術，應用於台灣舊社考古學研究。屏東縣來義鄉的排灣族文樂舊社為例，將本區以考古學方法測繪之全區聚落平面圖與政府現有之空載光達資料比對。在地理資訊系統的協助下，我們分析了兩者之間的異同，並討論光達資料應用於台灣山區原住民舊社考古學研究的可行方向。

The archaeological study of abandoned indigenous settlements in the mountains of Taiwan is often restricted by thick vegetation and difficult terrain. Some of these sites are in inaccessible known areas and it is unlikely that they could be located by investigators on foot due to the difficult mountainous environment. The sites we are able to locate were often covered with thick vegetation, which requires massive energy and time to clear before any study can be done. Our research applies the airborne LiDAR to the study of the above-mentioned sites. We compared the site layout of Wun-lou, an abandoned Paiwan settlement, mapped by archaeologists in 2014 with the data provided by airborne LiDAR from the government, using GIS. Through this comparison, we provide an evaluation and suggestions as to the application of LiDAR data to the archaeological study of abandoned indigenous settlements in the mountains of Taiwan.
