| Abstract: | 近年來，於永續發展為主要目標之一的規劃理念下，土地混合使用再度受到國內外的關注。混合使用看似簡單，但卻複雜，至今仍有一些研究缺口：如混合使用與密度、可及性的相互糾結；混合使用於不同面向、不同影響機制時，其採用的指標、空間尺度可能不同；混合使用所牽涉的面向，除住宅與交通行為外，亦包括建築與基地設計、混合街廓規劃、商業型態、社會文化因素等。基此，本研究的目的有三：就住宅、都市規劃、交通、經濟、社會文化等面向探討（1）混合使用的概念、定義、與影響或作用的理論基礎；(2)混合使用與住工混合、可及性、與密度等相關概念或指標的關聯性；(3)混合使用指標與空間尺度的選取、及其實際操作。研究方法以文獻回顧為主，實例模擬為輔，為質性與量性研究的綜合；其主要資料來源為國際與國內的期刊論文、法令、與實務界報告。實際模擬案例為台北市，其主要資料來源為2000 年台北市稅捐稽徵處的房屋土地使用資料，資料單元為門牌；輔助模擬資料包括相關地理資訊系統（Geographic information systems, GIS）圖檔；空間資料處理的工具為ArcGIS、 Excel
Mixed land use regains its popularity in many developed and developing countries as sustainable development becomes planning mainstream. However, a few research questions about mixed use remain incompletely answered. For one, the concept, indexes, and impacts/roles of mixed use are not completely clear, in particularly they may be different from various aspects such as housing, urban planning, transportation, economics, etc. Secondly, mixed use seems entangled with density, accessibility, and even jobs/housing balance. Finally, the selection of mixed-use variables and spatial scale of its measurement may vary from different aspects, too. Consequently, this paper aims to accomplish the following tasks: (1) to clarify the concepts, definitions, impacts or roles of mixed use from various aspects; (2) to disentangle the relationship between mixed-use, density, and accessibility; and (3) to shed lights on how to select mixed-use variables. These tasks will be conducted through literature review, accompanied by simulation analysis on mixed-use variables with Taipei as a case study. The primary data sources include land use data, and Geographic Information Systems (GIS) coverage |
