過去有關日治時期臺灣地圖的研究，大多關注在官方繪製的地形圖與主題地圖，相 對的，民間所繪製的地圖，以及地圖與常民社會之互動，則較少有人探討。有鑑於此， 本文係以水圳地圖為例，探究日治時期民間地圖發展與水利開發之關係，分析資料為 1902~1928年《臺灣總督府檔案》中所附之「私設埤圳圖」。透過Brian Harley所提出的 解構地圖 (deconstructing the map) 分析觀點，本文擬探討私設埤圳圖發展的政治和社會 脈絡，藉以了解這些地圖所反映的水利制度和社會文化變遷，以及地圖的內容和技術特 色。研究結果發現，私設埤圳圖的發展與民間自力興建水圳制度的延續、民間專業製圖 者的興起，以及官方地圖資訊的開放和流通息息相關。藉由上述之發現，本文希冀有助 於了解殖民統治下地圖與民生產業之連結、民間對於地圖的需求，以及人民參與製圖之 可能性。

This paper investigates the interplay between mapmaking and irrigation development driven by local society in Taiwan during Japanese colonial period (1895-1945). The maps analyzed were titled as Private Irrigation Maps produced during 1902-1928, currently deposited in the Sotokufu Archives. By reflecting to the discourses of “deconstructing maps” proposed by Brian Harley, this paper aims to examine the political and social forces underlying the mapmaking. The findings show that the development of Private Irrigation Maps was driven by the continued growth of local-initiated irrigation systems, the rise of professional civilian mapmakers as well as the release of official cadastral and topographic maps during the Japanese colonial period. It is anticipated the findings contribute to a deeper understanding regarding the civilian demand for maps and participation in map-making in a colonial context, thereby generating new insights for colonial cartography.
