基于IPA分析法的民国历史住区保护更新实施评估方法与优化策略研究：以南京为例

Historical settlements in the ROC period is an important type of historical relics. It is necessary to carry out a scientific evaluation on the implementation work in recent years. The evaluation of planning implementation for Nanjing ROC historical settlements, the IPA based methods and the further optimization strategies will be studied in this research. First, based on the unique typology and the planning standards, the appropriate indicators will be selected to establish a comprehensive evaluation system. Subsequently, divide the evaluation factors into objective and perceptual ones, the correlation between the two types of indicators will be studied. Then, based on IPA analysis, by assessing the perceived performance of ROC historic settlements, the social satisfaction for the implementation will be concluded. Meanwhile, the objective evaluation will use GIS to analysis the actual physical changes. By comparison between the public and experts, objectivity and perception index, an optimal evaluation methods and a complete evaluation findings will be developed. Finally, based on IPA grid, a priority order will be found to target the follow-up strategies. The study is expected to establish the planning implementation evaluation framework for ROC settlements, to improve the long-term mechanism of "Planning - Implementation - Evaluation - Feedback - Optimization" process, and to promote the dynamic protection process of the ROC history settlements.

民国历史住区是我国近现代历史文化遗存中的重要类型，近年来完成了大量实施工作，有必要对此进行科学评估和实时反馈。研究拟对南京民国历史住区的保护更新工作进行实施后评价，探索基于IPA分析法的评估方法，并对后续优化策略展开研究。首先，基于保护规划编制标准和民国历史住区的类型化特征，提取适宜指标，建立实施评估综合评价体系。随后，将评价因子分为客观性和感知性评价指标，研究两种类型指标之间的相关性。继而，基于IPA分析法，对代表性案例的感知绩效进行评估，考察实施工作的社会满意度。同时，将客观性评价指标录入GIS平台分析其实际变化。通过比较公众与专家、客观性与感知性指标间的差异，优化修正评价方法，形成完整评估结论。最后，基于IPA方格得出优先级顺序，研究针对性后续策略。研究预期初步建构历史街区保护更新规划实施评估框架，有助于健全“规划-实施-评估-反馈-优化”的长效机制，促进民国历史住区的全程动态保护。

作为我国近现代历史文化遗存中的重要类型，民国历史住区的大量保护利用实施工作，需在完成后进行科学评估和实时反馈。本课题在对南京老城区居住形态演化分析的基础上，首先从“规划目标完成情况”和“社会经济综合效益”两大主要评价角度，基于保护规划编制标准和民国历史住区的类型化特征，提取适宜指标，构建了民国历史住区保护综合评价体系；再以IPA分析法作为感知绩效对评价体系进行修正；进而选取六片三类典型民国历史住区样本进行实证研究；最终制定民国历史住区适应性保护更新后续策略。研究表明，以保护更新工作进行实施为主的实施绩效综合评价体系，需要感知绩效的再平衡，公众与专家、客观性与感知性指标间的差异，有助于建构历史街区保护更新规划实施评估框架，健全“规划-实施-评估-反馈-优化”的长效机制。本课题研究对象类型化，研究角度对后续优化策略实施评估具有针对性，量化实证完善后续保护更新策略制定体现科学性。
