摘要

近年來文化資產維護保存議題已普遍受到重視，然而野郊地區有形文化資產因地形與環境影響，長久下來將對其結構體產生破壞威脅。本研究利用無人機可對小區域範圍監測之機動性，搭載多光譜感測器對金門野郊地區國定古蹟陳健墓與陳禎墓周圍地物進行資料蒐集，並提出一套環境風險評估模式。該模式考量氣象與土壤含水量作為危害度因子，以及地形坡度為脆弱度因子，將監測分析資料以四分位距統計劃分為四級距，以產製不同時期兩墓園環境風險等級圖。研究結果顯示，所產製的多時期環境風險等級圖，可細緻化呈現有形文化資產各部位承受之環境風險等級，除了作為辦理修復計畫時設置減災設施參考外，並有效指出兩墓園有形文化資產不同季節承受環境風險之差異。

Recently, the issue of maintenance and preservation of cultural heritage has been widely given attention. However, physical cultural heritage in wilderness areas would suffer from the threat of destruction due to the long-term terrain and environmental influences. This paper considered the flexibility of a multispectral sensor mounted by an Unmanned Aerial Vehicle (UAV) for small-scale monitoring to acquire the multi-temporal UAV images for the two national historic sites (i.e., the Chen-Jian and Chen-Zhen monuments) in the wilderness areas of Kinmen and propose an environmental risk assessment model. In the model, meteorology and soil moisture are regarded as the hazard factors, while the slope of terrains is regarded as the vulnerability factor. By an inter-quartile range statistic for the analyses of the monitoring dataset, the environment risk was described into four grades to produce the thematic maps of environment risk. The experimental result demonstrates that the produced multi-temporal thematic maps of environment risk can present the environment risk grades borne by the different portions of the two monuments in detail. Thus, the thematic maps not only can serve as references for installing the mitigation facilities while performing a restoration plan, but it can also effectively indicate the seasonal differences in the environment risk grades between the Chen-Jian monument and the Chen-Zhen monument.
