本文以 1915（大正4）年前後浸水營越道東段沿線的姑仔崙、イチヨカラ、 浸水營，及中部雪山坑、サラマオ、シカヤウ等6 案例，從興建計畫、興建過程、平面類型、實體架構、設備整合、以及防禦性等面向，討論其相似性與歧異性，以呈現在理蕃體系、理蕃政策發生大幅變動的1915（大正4）年前後蕃地基層警察機關駐在所的建築形貌。本文認為，1915（大正4）年確實是駐在所建築形貌變遷的關鍵年代。此時駐在所建築的形貌，呈現多元、多樣的特性，並沒有統一的樣式風格，似也沒有相關建築標準或規範。看似不相同的平面，可區分為：中央走道型、一字型兩種，從空間大小、設備整合程度及相關案例分析，推論出中央走道型平面是較早期的，而一字型平面是較後期的作法。1915（大正4）年前後的駐在所建築，為了兼顧彼此矛盾的兩大需求：做為「文明櫥窗」的示範與可及性，及以廳舍建築物為最後防線之防禦阻絕性能，因而反映在建築細部之上。自1915（大正4）年起，當局將前期隘勇線作戰時、及歷次遭原住民襲擊的建經驗，用以改良「集團化據點式」駐在所廳舍的平面配置，舊有中央走道型平面被逐漸被兩組宿舍單元夾著辦公室的一字型平面所取代。

This article is based in the 6 paradigm cases built around 1915: Kuwaron, Ichiyokara and Sinsuie along the eastern section line of Jinshuiying (Sinsuie) lateral trail, as well as Setsusanko, Saramao and Shikayau in central Taiwan. The author compares to the cases’ programming, process for construction, plans, physical structure, integration of device, and defensiveness, and tries to explore the similarity and diversity on the architectural morphology of police substations around 1915: the year of the drastic changes on the institution and policy for ‘Control of Aborigine’. 1915 was the key era for architectural morphology changes of Chuzaisyo (Police Substation) in Indigenous Area of Taiwan. At this time, the architectural morphology of Chuzaisyo rendered multiple and diverse characteristics and there was no uniform style. And it seems there is no relevant architectural standard or specifications. Different plans can be discriminated to the central-corridor style and the straight-line style. According to room size and device integration, it is inferred that the central-corridor plan should be earlier than straight-line plan. In order to balance the competing two major needs: being the model and accessibility of “window of civilization” as well as functioning the last line of defense denial of the office and quarter buildings, and it was reflected in the details of Chuzaisyo architecture around 1915. Onwards from 1915, based on the experiences of the battles in the Guard Lines and the buildings being attacked by indigenous, the authority improved the plan layout into the “collectivized stronghold” police substations from the central-corridor style into the straight-line plan style – office in between two quarter units gradually.
