浅议“叠合分析法”在古镇保护改造中的运用——以云南通海县河西古镇保护改造为例

Discussion on the Method of Data Superposition in Conservation Planning of a Historic District:a Case Study of Hexi Protection Transformation in Yunnan Province

在中国的历史城镇街区改造中,由于前期分析的不足,导致许多有价值的历史建筑被拆毁,笔者从这些问题出发,在云南河西古镇的保护改造中,将伊恩·麦克哈格的著作《设计结合自然》中所叙述的叠合分析法引入建筑保护领域,并与层次分析法相结合,构建了叠合分析法在历史地区保护改造方面的应用体系。再以此为基础,详细介绍了叠合分析法的叠合步骤,以及对叠合分析成果的使用方法,并探求其相对于常规分析方法,在综合性与客观性上的进步之处,为后期的保护规划提供更加科学易用的"扬弃"依据。

In many projects of protection and renovation of the historic district in China, plenty of historic architecture had been dismantled with insufficient pre-phase analysis. For all these consideration in protection and renovation project of Hexi historic town, the author introduces method of data superposition of description in lan L. McHarg＇s book 〈 design with nature 〉 in the field of architecture heritage conservation, constructs the application system of method of data superposition in the field of architecture heritage conservation. On this basis, steps of method of data superposition and the using method are described in detail. And it seeks the improvements of objectivity and integrity comparing to traditional analysis to provide more scientific and easier sublation reference for protection planning.
