Study on Diversified Evaluation of Residential-Type Historical and Cultural Blocks in Guangzhou

Abstract

Historical and cultural blocks contribute to urban cultural construction in a very significant way. Regardless of their specific types, historical and cultural blocks not only add brilliance to the cultural heritage of cities but also take on more urban responsibilities through actively expanding their use values. This perfectly embodies the diversified protection and development of traditional blocks. In discussing the diversified development achievements of a block, its users usually have the most since their behaviors are closely related and mutually interactive with block environments. In this sense, collecting user evaluations helps to identify the diversified development status of a block from the inside and explore more values. Considering that the residential-type historical and cultural blocks in Guangzhou have realized diversified development in terms of location values, function expansion, and user integration, this paper takes two typical blocks in the city for a case study and performs user evaluation analysis. Evaluation data are collected through traditional questionnaire surveys and text mining to expand the scale of access to information and enhance data flexibility. An evaluation index set is established for residential-type blocks by discussing the achievements of the diversified block developments and extracting the key factors of block environments based on data analysis. The research results of this paper provide a basic framework for the in-depth analysis of blocks and evaluation models building and offer suggestions of protection and design for other blocks.
