摘要

農路為農村生產資材與產物運輸之交通要道，維護山坡地住民行動安全之命脈。已錄案編號農路計有8,678條，位於山坡地者為4,711條；但仍然存在為數不詳的且符合農路定義之道路，雖非屬編號農路，惟其功能與編號農路同樣重要。因此本研究以臺灣通用電子地圖為底圖，篩分山坡地上可能為農路者計273,199條。再選出6區土石流自主防災内1,129條可能農路進行現地複核，顯示有1,006條與圖資相符，吻合度達89.1％。其中符合農路定義者為607條，故本研究可能農路圖資篩分正判率可達53.8％。最後提出該圖資整併方法，可由273,199條減少至76,503條，減幅達72.0％，此一成果可供相關單位參酌，以期能提升山區防災與生活發展。

Agricultural roads are the main traffic arteries for the transportation of production materials and products in rural areas. There are 8,678 recorded agricultural roads and 4,711 on hillsides; but there are still an unknown number of roads that meet the definition of agricultural roads, which are equally important. In this study, Taiwan's general electronic map was used as the base map, and 273,199 roads on the slopes were screened. A review of the 1,129 possible agricultural roads on the spot showed that 1,006 were in line with the map, and the agreement reached 89.1%. Among them, there are 607 that meet the definition of rural roads, so the positive judgment rate of the map data screening in this study can reach 53.8%. Finally, a consolidation method is proposed, which can be reduced from 273,199 to 76,503, a redaction of 78.09%. This result can be considered by relevant units in order to improve mountain disaster prevention and life development.
