历史街区形态与社会网络结构相关性探索

A Study On The Relevance Between Physical Form And Social Network Of Historical District

为保护历史街区形态与社会网络结构,改善快速城镇化进程中历史街区出现的传统风貌破坏、形态急剧消失、社会结构日渐瓦解等现象,基于社会网络分析方法,文章以重庆偏岩镇、白沙镇及宁厂镇3个国家级历史文化名镇为例,构建核心保护街区的居民户"点"单元与社会关系的"线"关系语义模型,在Ucinet6.0平台上构建社会网络拓扑结构。建立由社会网络整体完备度、局部稳定度和层级关联度构成的结构稳定性评价体系,并基于评价结论着重分析历史街区形态与社会网络结构形态的相关关系,为历史街区的形态与社会网络保护提出规划策略。

To protect the physical form and social network of historical district,the paper takes Pianyan town,Baisha town,and Ningchang town as examples,establishes a semantic model that preserves social“node and line”relation and a topological structure on the Ucinet6.0 platform with social analysis method.It also establishes a structural stability evaluation system consisting of social network integrity,partial stability,and layer relevance.Based on the analysis of relevance between physical form and social network,the paper proposes planning strategies for better preservation of physical form and social network of historical district.
