数字化技术和量化分析应用于大遗址保护规划的创新与实践——以郑韩故城为例

Innovation and Practice of the Research Methods for Large-scale Site Conservation Master Plan in the Context of Urban Development: A Case Study of the Capital of Zheng and Han states

在城市快速发展的背景下,与城市叠压的大遗址保护困难重重。如何具体统筹协调遗址保护与城市发展之间的关系,是编制文物保护规划时需要着重思考的问题。以郑韩故城保护规划修编项目为例,针对遗址所面临的困境,运用数字化技术手段,建立保护规划智能分析平台,并以此为支撑,对遗址与城市的各类空间数据进行多维度分析,量化两者之间的关系,找出原有保护规划存在的问题,从而有针对性地制定出合理的规划策略与管理措施。这种基于遗址与城市关系为重点研究方向之一,以数字化分析为手段的保护规划方法,对于此类大遗址的保护与利用具有一定的借鉴意义。

In the context of urban development, the effective conservation of ancient city sites overlaid with modern cities has been a bottleneck to cultural heritage conservation management. Traditional approaches in conservation plans mostly formulate regulations of city management based on subjective judgment from the perspective of heritage sites. Without a corresponding assessment for the applicability of the strategies, these approaches result in a disconnection between site conservation and urban development.Exemplified by the revision project for the conservation master plan of capital of Zheng and Han states, this paper focuses on coordinating the relationship between site conservation and urban development in response to the difficulties in implementing conservation measures and satisfying the needs of old city renovation and new countryside construction in the former master plan. Compared with the traditional approaches in conservation master plans, this paper makes a new attempt to coordinate the relationship between conservation and development. Firstly, using digital approaches, it collects three-dimensional geographic information of the capital of Zheng and Han states and the city center of Xinzheng, and establishes a database and an intelligent analysis supporting platform,achieving accurate and intelligent data analysis. Secondly, it performs multi-dimensional analyses on urban development progress,conservation zone scope, urban land type, urban construction scale, illegal construction scale, and other data on the platform, showing an honest and holistic data relationship between the site and the current city. Thirdly, it proposes the analysis method of balance of payment, effectively assessing whether the building height management control in the former master plan is suitable for the urban construction status and development needs. These methods play a decisive role in formulating reasonable planning strategies.
