【摘要】 城市更新伴随城市发展的始终,是城市新陈代谢的有力保障。当城市的物质空间不能满足人类需求且城市土地拓展受到限制的时候,人类将目光转向城市更新,通过功能和空间的重新组合来释放更多的物质空间。城市更新是城市化进程的必经过程,故对我国城市而言也不例外。近年来,我国城市化进程飞速发展,土地的面积显得尤为不足,城市更新工作显得尤为必要。成都作为西部重要的枢纽城市,其城市更新工作如火如荼的开展着,其发展的模式和进程具有一定的代表性和典型性。本文立足于此,从外部空间设计的角度出发,以成都市北改片区棚户区为研究对象对城市更新工作进行探讨。首先,本文以国内外关于城市外部空间设计和棚户区改造的文献资料为研究基础,归纳相关理论,总结出外部空间设计的定义、方法和分类等理论;同时对棚户区的基本价值、组成要素和概念等进行整理和阐述,并通过总结曹家巷棚户区更新项目来探寻外部空间设计的经验和手段。其次,对成都市北改片区棚户区外部空间的进展进行概述,将棚户区和改造后的安置房小区进行对比,运用卫星影像图、现场图片、图形分析(平面、立面及剖面)以及问卷调查等形式以整体肌理、功能结构、空间秩序、空间要素、场所精神为主要分析对象对整体结构进行研究,并将空间要素分为道路、广场、公园等,从基本特征、尺度和比例、街道立面和天际线、景观和绿化及人为活动等角度进行细化研究,运用相关评价方法对其空间质量进行评价,并通过居民的主观感受来探索棚户区外部空间给人的空间感受。在此基础对比归纳出棚户区改造前后外部空间的特征及变化,探讨外部空间设计过程中存在的问题:整体上,空间尺度较小,功能混杂,交通混乱且土地利用率不足;街道空间D/H比值过大、街道立面不活跃、天际线缺乏美感、绿化质量差;广场和公园尺度太小、街道立面缺少自然风情、景观单一、配套不足;院落空间尺度太小、街道立面单调、景观协调性差、配套不足。最后在上述研究的基础上,从高效化、复合化、人性化、传承性、连续性等基本理念出发,以改造前后外部空间特征为基石,总结出经验性设计原则,将其结合到城市改造过程中外部空间的设计中,扬长避短,为创造舒适宜人的外部空间环境提出合理的设计策略。成都市北改片区的棚户区改造是当今成都市发展的重大民生工程,也是全国棚户区改造进程中的一个缩影,能展现出棚户区的现存问题和矛盾。通过对其研究可以探索出城市棚户区的手段和策略。本文通过对其道路、广场和公园等外部空间设计研究,以期能将此理论基础运用到实际,创造更加美好宜人的空间环境,提升城市文化和物质空间质量。更多还原

【Abstract】 Tracking back to the history, urban regeneration accompanies the whole process of urban development has always been a powerful guarantee for the urban metabolism. When the city’s physical space and the land expansion can not meet the current requirement of human, people will turn to urban regeneration by recombining the old functional area and space. China’s city is no exception, In recent years, the urban regeneration work is particularly necessary with the rapid development of the process of urbanization in China. In this paper, the design of the outer space in the urban regeneration process of shanty towns in the north of Chengdu was discussed.This paper focuses on the design of the outer space of shanty towns in the urban renewal of Chengdu. Firstly, based on the domestic and foreign literatures on the design of external space, the relevant theories, definition, methods and classification theories about external space design has been summarized, and the implication of Graph theory , Place theory and Connection theory has been discussed. Secondly, the progress of the outer space of the shanty towns in the north area of Chengdu is summarized. By comparing the images of the unfinished shanty towns with those of the newly built squares, the satellite images,the field pictures and the graphic analysis (plane, elevation and profile) And other forms of the overall structure, functional structure, road context and spatial level as the main analysis of the overall structure of the two studies, and external space is divided into roads,squares, courtyards, from the basic characteristics, scale and proportion, interface and flow Line, landscaping and greening, and human activities. The evaluation method is used to evaluate the spatial quality. Based on the comparison, the characteristics and changes of the outer space before and after the regeneration are summarized. The influence of the external space design process Finally, on the basis of the above research, this paper summarizes the empirical design principles from the concept of humanization and regionalization, and takes the characteristics of exterior space before and after the renovation as the cornerstone, and combines them into the outer space of urban renewal process The design, to avoid weaknesses, to create a comfortable and pleasant external space environment, a reasonable design strategy.Chengdu North to Shantytowns Area ’s transformation is the significant development of chengdu people’s livelihood project,also is a microcosm of the nation’s shanty towns transformation process, can show a shanty towns of the existing problems and contradictions.The research can explore the methods and strategies of shantytowns in China. This article through to its roads, squares and parks of external space design research, such as to apply this theory to practice,to create a more beautiful and pleasant space environment,improving the quality of urban culture and the material space.更多还原
