摘要

本研究以臺灣三處遺址範圍為研究區，整合1976～1978與2016～2017年航空照片與數值航測技術，進行土地利用與地形變遷對遺址破壞程度偵測之研究，並分析影響文化層擾動之空間關聯顯著因子。研究結果顯示各遺址於1976年至2017年間普遍受到高密度土地使用影響，人為屯墾、風水災害與工程建設所造成之地形變動為遺址文化層受破壞主因，其中又以私有土地為甚。基於此，以都市計畫手段進行土地徵收與土地管制有其必要性。未來將可應用此技術提高遺址管理成效並有效針對問題因子進行檢討。

Current situation and accumulated development of archaeological sites have very high impacts on the preservation value of the site. This research set 3 archaeological sites in Taiwan as study areas. Assessment of the degree of destruction of cultural layers due to land use change and morphological change were conducted with aerial photographs (1976~1978; 2016~2017) and digital aerial survey technology. The results showed that the archaeological sites were all seriously influenced due to the high land use intensity between 1976~2017. Morphological changes caused by human cultivation and engineering construction were main causes of site destruction, especially in private lands. Therefore, urban planning methods for land acquisition or land regulation are necessary. The prediction model of the destruction degree of the cultural layers of the site developed by the research team has also achieved good predictive ability. In the future, this technology can be applied to improve the effectiveness of archaeological sites management and effectively review the problem factors.
