本文試圖透過正史、地方志、族譜等史料及田野調查資料的考察與辨明，討論明清福建金門城的社會與空間變遷。首先，討論明初的政治空間計劃---衛所制度的設計，以及對於閩省海疆軍事佈署的築城運動；接著瞭解在此一政策下金門所城的興築過程，以及其社會形構與空間形式，並嘗試復原當時的市街結構與佈局；同時，分析衛所制度的式微與軍事城堡性質的轉化之關係；最後指出清康熙年間為了封鎖明鄭的遷界政策，以及遷治後浦的決定，導致了金門城的沒落。金門城「從軍事城堡到宗族聚落」發展之研究，一方面讓我們瞭解千戶所城的演變，一方面可作為明清以降中國沿海地區城鎮、聚落體系建立的先行研究。

　　　　　This paper examines the social and spatial change in Jinmencheng, Fujian during the Ming and Qing dynasties by drawing on official documents, local gazetteers, genealogy books, and field data. First, I　discuss the political and spatial dimensions of the Weisuo system in the early Ming dynasty and the process of construction outposts for coastal defense in Fujina. Second, I focus on the construction of Jinmencheng as part of the coastal defense scheme and its implications. Finally, the decline of the Weisuo system led to the transformation of military towns. Aw a result, Jinmencheng gradually turned into a lineage dominated town. The Evacuation policy, which forcing the residents of the coastal area, including those in Jinmen, to move inland as a strategy to counterattack Koxinga, was the last straw to break the camel's back. The implementation of forced evacuation scorched Jinmencheng. In consequence, the political center was switched to Houpu later on. This paper sheds light on the evolution of a military town and on the construction of villages and towns in the coastal area since the Ming.
