界壳理论视角下的历史城厢边缘地区城市设计方法探讨

Urban Design of Historic Quarter Marginal Area Based on Shell Theory

历史城厢因其丰富的历史资源和文化脉络成为城市历史文化保护的首选标的和空间范式。历史城厢边缘地区作为历史城厢的外围腹地,却长期成为老城区和新城区之间的“界壳”,区域定位不明、水绿特色不显、设施活力不足、空间形态失序,阻滞了新老城区的联动发展。文章从界壳理论视角切入,以无锡龟背古城边缘的运河湾地区为例,综合运用数字技术和城市设计手法,从功能界壳、景观界壳、活力界壳与空间界壳的维度探索历史城厢边缘地区的发展模式和城市设计方法。

Historic quarter is usually the spatial paradigm for preservation due to its rich historical and cultural resources.The marginal area of historic quarter,however,has long been the shell between old and new towns.It has problems in development orientation,green characters,spatial form and vitality etc.From the perspective of shell theory,the paper uses digital technology and urban design methods,studies the development model and design approaches of historic quarter marginal area from the aspects of functional shell,landscape shell,vitality shell,and space shell in the case of Canal Bay area of Wuxi Guibei historic quarter.
