The Dialectical Relationship of "Heritage Protection" and "Low Carbon"in Historical Urban Area and Its Urban Planning Response: A Case Study of the Old City Area of Ming Dynasty in Xi'an

如何调解文化遗产保护与温室气体减排之间的紧张关系是新时期需要回答的系统性问题文章首先在辨析历史城区中"保护-低碳"对立统一关系的基础上,明确了"保护-低碳"平衡是历史城区发展的重要目标;其次通过案例梳理,总结出底线保障、效益最大、系统整合、同步行动和渐进实施等平衡原则;最后结合西安明城区,提出涉及城区功能优化、开发强度控制、设施介入管控与建筑改造指导等4个方面的规划目标及途径,以完善"保护-低碳"的系统认知,指导历史城区发展。
