隋唐长安城遗址叠压区保护机制与导控模式研究

隋唐长安城遗址位于西安中心城区，当前城址已被城市建设大规模叠压，致使其难以辨识。其存在问题是遗址叠压区的大量潜在遗存始因终未被纳入已有保护范畴，长期缺乏有效保护机制与管控措施，致使遗产整体处于濒危状态。本课题基于隋唐长安城遗址亟待保护的紧迫需求，采用历史地理、城市形态、影响评估与动态模拟的定性定量统计与分析方法，拟开展如下研究：判定隋唐长安城遗产价值，确认遗产载体的构成系统；建立隋唐长安城遗址的科学完整遗产数据模型；辨别潜在遗存分布，提出遗产影响的分级评估原则与风险分类标准；制定分级分类保护控制策略，预防破坏性建设并引导主动保护与合理利用，构建隋唐长安城遗址叠压区的有效保护机制与导控模式。本课题为遗址叠压区的遗产可持续保护与利用提供理论依据与实践指导，对建筑遗产保护领域中处于城市建成环境的大遗址保护研究具有重要学术意义，在实现遗产整体有效保护与社会长远发展的协同推进中具有广泛应用前景。

Sui-Tang Chang'an City Site is located in the central Urban Area of Xi'an, the Site area has been large-scale superimposed by Urban construction which makes it difficult to identify. The problem is that a large number of potential remains in the site superimposed area have not been included in the existing conservation category, and the long-term lack of effective conservation mechanism and control measures, resulting in the overall state of heritage endangerment.Based on the urgent need to protect the Sui-Tang Chang’an City Site, this study uses the quantitative statistical and analytical methods of Historical Geography, Urban Form, Impact Assessment and Dynamic Simulation to carry out the following research: .Determine the value of the heritage of the Sui-Tang Chang’an City Site, confirm the composition system of the heritage carrier..Establishment of a scientific and complete Heritage Data Model of Sui-Tang Chang’an City Site..Identify the Distribution of Potential Heritage, put forward the Principles of Grading Assessment of Heritage impact and risk classification criteria. To formulate graded and classified conservation and control strategies, prevent destructive construction and guide active conservation and rational utilization, build an effective conservation mechanism and guidance mode for the superimposed area of the Sui-Tang Chang’an City Site. This topic provides theoretical basis and practical guidance for the sustainable conservation and utilization of Heritage in the site superposition area, it has important academic significance for the conservation of large archaeological sites in urban built environment, with regard to the research into in the field of Built Heritage conservation, significant academic value is featured in the project this report proposes, and it also has broad application prospects in realizing the coordinated promotion of the overall effective conservation of Heritage and long-term social development.
