摘要
城市设计作为一种引导城市空间营造行为的技术实践,具有系统性、开放性和丰富性的特征。现代城市设计面临的挑战如此复杂,已远超传统的空间美学范畴,需要融入众多相关学科和工程技术,尤其是数字技术,推动城市设计工作更为综合和科学。本文以重庆前沿科技城城市设计为例,探索在山地型的城市建设区,如何在满足合理建设强度,并承载既定发展目标的同时,针对山地环境特点,抛弃强力改造地形的常规手法,探索低影响开发的各种手段;并研究如何依靠现代的可量化技术工具,有效降低工程成本,综合达成产业、宜居、活力、高效、生态、节能、智慧等多元化诉求。这一方面为城市设计影响、完善甚至修改法定规划提供了强大的技术支撑;另一方面也为城市设计有效引导后续具体的开发实践提供了重要的技术依据。案例中运用的可量化技术工具涉及山水空间、生态保护、安全保障、海绵城市、市政能源以及风环境模拟等方面。
As a technical practice guiding urban space （re）creation, urban design is characterized by systematicness, openness and richness. Modern urban design is facing growingly complex challenges, far beyond the scope of traditional space aesthetics, and needs to integrate many related disciplines and engineering technologies, especially digital technologies, which make the urban design work more comprehensive and scientific. The paper studies on the urban design of Chongqing Frontier Science City. Instead of using conventional way of strong terrain transformation, the plan explores various means of low impact development （LID） to meet reasonable construction density and development goals. The paper also studies on modern quantifiable technical tools to reduce the cost and meet diversified demands in industry, livability, vitality, efficiency, ecology, energy conservation and intellectualization. Consequently, urban design provided strong technical support to influence, fulfill and even modify statutory planning; meanwhile, it is equipped with important technical basis to guide subsequent engineering practice effectively. The quantifiable technical tools used in the case involve landscape space, ecological protection, safety guarantee, sponge city, municipal energy and wind environment simulation, etc.
