Conservation and Development of Residential-Type Historical and Cultural Blocks in Guangzhou under Subjective Evaluation.

Historical and cultural blocks not only carry numerous cultural heritages but always undertake urban functions. As a major driver of urban context construction, historical and cultural blocks have never been abandoned by the times. Regardless of the purposes for which they were built in the first place, all historical and cultural blocks should be extended functionally to rejuvenate them in current and future developments. In particular, in single-functional residential-type historical and cultural blocks, the large numbers of traditional architectures left vacant by out-migrating residents can be redeveloped for other functions. The effectiveness of block conservation and development affects the cultural construction of a city. More importantly, it is closely related to all kinds of users in blocks, as users engage in in-depth interactions with environments and are best able to discover the merits of block conservation and development. Moreover, the conservation and optimal design of historical and cultural blocks must, ultimately, be based on the users' needs. By collecting users' subjective evaluation opinions about two typical residential-type historical and cultural blocks based on the existing evaluation index and putting them through quantitative analysis, this paper analyzes block status in many aspects. It identifies focuses on optimization, offering references and suggestions for future development. [ABSTRACT FROM AUTHOR]
