都市流體－台北地下捷運站的空間共構

台北在捷運出現後，都會區的捷運站多分佈於城市地下，亦開啟了一個台北地區的新層次。人們每天生活依賴捷運，捷運站成為生活過渡的轉譯空間，也因為捷運快速便捷之特性，讓捷運與人的關係成為一組都市中的流體。此過程中，讓人們多了一個體驗台北的方式，人們漸漸失去以往塞車過程中對於都市的線狀思考；相反的是點與點間的區域性關係。因此，捷運站空間成為地區印象重要的出入口，也提供許多空間共構的機會；甚至在街道經驗逐漸地下化的同時，亦能利用捷運網絡關係，構思新的捷運站開發策略。以下為本研究各章節概要：第一章以本身體驗台北的過程出發，說明本研究之動機目的與核心議題，並呈現本研究進行之流程架構。第二章就三個本研究所涉略的議題，進行文獻回顧。在文化地理學中，透過變遷地貌的討論，到文化地理學之刮除與重寫概念，作為檢閱台北城演進的方法；在都市捷運部份，重點回顧捷運、交通與都市發展之關係；最後討論三個不同國家之地下空間發展經驗。第三章透過生活物件、多功能建築再到商業空間的共構討論，分析其中結構。在後現代複合文化的時代之下，解析建築與空間計畫的複合特性，藉此特性掌握主題空間的共構策略與方式。設計發展方面，針對都市流體之議題，進行釐清；基地選擇於首都核心區的四個地下捷運站內，以誠品書店作為假設業主，進行捷運站共構之操作，之中配合在地特色進行書店主題的營造，企圖配合捷運系統運作，創造一個新的漫遊地點於捷運車站內，提供捷運在交通服務外的使用機能，塑造一個捷運站作為過渡空間之外，成為目的地的可能。捷運已經成為台北人生活重要的一部份，在捷運網絡的架構下，捷運站的設置成為地區發展的關鍵，就都市發展而言，這些捷運站空間都是契機，可透過共構的過程使其更具功能性，對於未來的台北，如何讓捷運不只是交通服務設施，係為本研究最終之冀盼。

Abstract： Most of the urban MRT stations distribute underground and create a new living area for Taipei city after the appearance of MRT. Because of the speed and the convenience, the inhabitants depend on MRT to get around Taipei city everyday, and it makes these MRT underground stations become very important transferring spaces. The relationship between MRT and the people turns into a urban fluid in Taipei city. The way people move in Taipei now becomes “node to node”－one station to another, instead of been in traffic jam. Underground stations make the city’s impression more and more regional; in the meantime, they become important gates to several districts in Taipei. Consequently, Taipei MRT underground stations must need new concepts of developing strategies. The following is the brief introduction of the contents of each chapter： Chapter1 Illustrating the background, purpose, the major subject and the process of this research. Chapter2 Review of the three subjects: In Cultural Geography, discussing the evolution of Taipei city by looking at the changes of the artificial relief in Taipei and the concept of Scrape and Palimpsest. In urban MRT, we will review the relationship of traffic, MRT and the city developments. The discussions of the historical documentations in underground spaces developing in three different countries will be involved. Chapter3 Discussing and analyzing characters of multi-function structures in the post-modern; and the strategy of complex spaces in this study came from this concept. Chapter4 Taking the urban fluid and complex spaces as major subjects in design. I chose four MRT underground stations in central Taipei as the sites of this study. In addition to original function of communications, my attempt is to create various theme spaces in the stations for people to roam around. Chapter5 MRT stations have become crucial locations of regional developing in Taipei city. Complex spaces can make the underground stations much more functional which will be very beneficial in the city’s prosperity. How to make a good use of MRT and let it be more than just a communicating tool for citizens are important works to be done for the city of Taipei.
