3、ty, Chongqing, China May 2012I 摘 要 纵观国内外数千年的城建史,大部分城市都是以旧城为源头逐步向外延展和 拓张。作为城市的雏形与根源,旧城区在特定的历史时期和条件环境下形成,经 过若干年不懈的积淀和发展,酝酿出了厚重和丰富的地域文化和民俗风情,为城 市铸就了独有的物质环境风貌与精神气质,可以说,旧城区对于一个城市而言, 代表的是一种独一无二的印记,是无价的历史文明财富。随着中国城市化进程的 不断加深,土地资源日益紧张,促使城市旧城区成为新一轮的开发对象。在己经 实践的许多旧城改造与更新过程 中,大规模的推倒重建和脱胎换骨式的更新模式 在举国上下屡见不鲜,城市在物
4、质环境得到一定改善的同时却付出了大量历史文 化与场所精神遭受灭顶之灾的巨大代价。因此,寻求一种适宜我国旧城改造与更 新策略,在城市历史文脉得以传承、场所精神获以延续的基础上,实现旧城区历 史地段物质更新、功能适应性调整、经济复苏、街区活力再现是十分必要的。 本文结合研究生阶段参与的工程实践项目 一一 四川宜宾中国酒都特色街区南 区规划,详细论述了城市触媒理论在旧城改造与更新中的具体应用,并论证了通 过策略性合理地植入触媒元素并加以适当的疏理 引导是解决当下旧城区改造与更 新项目中各种矛盾的一种有效方式。 文章绪论部分首先对项目产生背景、我国当前己经实践的旧城改造与更新的 现状以及相关理论发展背
5、景进行了简要介绍,在此基础上确立了基于“城市触媒理 论”的旧城改造与更新策略为论文的主要研究内容。随后对论文的研究目的、意义, 研究方法做出论述并提出论文的组织结构。 第二章节主要对“城市触媒”作为一种新的规划思想及实施策略植入旧城改造 与更新实践中的可行性进了论证,从理论层面确立了“触媒式”规划策略在旧城改造 与更新情景中的合理有效性。 在理论确证的基础 上,文章第三章结合实践项目具体地对“触媒式”改造与更新 的应用策略、触媒反应过程以及触媒效果模拟作出了详解的介绍。 文章第四章基于前文的论述,对“触媒式”旧城改造与更新实践成功的要素进行 了总结,再次结合实践项目本身对“触媒式”改造与更新的
6、三个重要层面进行了系统 性归纳总结,具体涉及到“触媒”的形态类型、应用策略划分以及作用特征。确证了 基于城市触媒理论的旧城改造与更新模式可以在保证旧城区历史文脉、场所精神 得以延续的基础上,实现旧城区的物质更新、功能适应性调整、经济复苏、街区 活力的再创造,是适宜我国 a 下 旧城区现状的改造与更新模式。 关键词:旧城改造与更新,触媒,宜宾 n ABSTRACT In the thousand years5 urban construction, most cities have been constantly expanded and evolved by centering on the
