基于POI数据和SD法的历史镇区评价研究——以溱潼古镇为例

Research on Historical Township Evaluation Based on POI Data and SD Method——A Case of Qintong Ancient Town

历史镇区作为城市的重要组成部分,不仅具有当地的地域特色和多元文化,同时在现代社会具有很高的精神价值和发展价值。文章以溱潼古镇为例,基于POI数据,对各类设施进行归类整理,挑选出古镇居民经常进行活动的公共服务设施类型,建立溱潼古镇公共服务设施点空间数据库,将古镇分为不同种类的生活圈。运用SD法,从人的感受出发对古镇空间体验进行量化评价,将量化结果与客体指标进行比对。结果表明,热闹度、设施完善度和建筑形式丰富度是古镇富有活力的重要保证,而历史古迹数量、曲折度、商铺数量等客体指标与这些心理量有一定的相关性。最后提出历史镇区的改造需要从使用者感受出发,才能让建筑空间更好地贴近生活。

As an important part of the city,historic towns not only have local regional characteristics and multiculturalism,but also have high spiritual value and development value in modern society.Taking Qintong Ancient Town as an example,based on POI data,this study screens and classifies various facilities,screens out the types of facilities that conform to the daily behavior of the residents of the ancient town,constructs the spatial database of public service facilities in Qintong Ancient Town,and divides the ancient town into different kinds of life circles.Using SD method,this paper quantitatively evaluates the spatial experience of ancient towns based on people’s perception,and compares the quantitative results with the object indicators.The results show that the liveliness,the perfection of facilities and the richness of architectural forms are important guarantees for the vitality of the ancient town,and the number of historical sites,twists,shops and other object indicators have a certain correlation with these psychological quantities.Finally,it is pointed out that the transformation of historic towns needs to proceed from the user’s feelings in order to make the building space closer to life.
