Research on Renewal Strategy of Historical and Cultural Blocks from the Perspective of Tourist Perception

As a special part of the city, historic district is a unique scarce resource, which combines various functions and cultural memory. However, looking at the protection of historical and cultural blocks in our country, its transformation mode is either to carry out demolition and reconstruction, or to be in a rigid static protection. How to explore a sustainable development road that balances development and protection is very important for historical and cultural blocks. From the perspective of tourists' perception, through qualitative research and comparative study on tourists' online comment text, the change of tourists' perception of the study area is obtained, which provides a new way for evaluating the renewal strategy of historical and cultural blocks. The findings are as follows: (1) Tourists' perception of historical and cultural blocks mainly includes the landscape style of the blocks, the commercial form of the blocks, the traffic environment and the cultural atmosphere of the blocks. (2) The reason for the difference in tourists' perception lies in the value orientation and implementation effect of the renewal strategy. (3) The development dilemma of Nanluoguxiang lies in the low quality of commercial forms within the block, the high traffic pressure within the block and the high degree of homogeneity of entrepreneurial forms. Throughout the renewal process of historical and cultural blocks, it can be said to be a microcosm of urban renewal to some extent.
