Street spaces in historic districts are now facing challenges such as loss of vitality and deterioration of spatial quality. Maintaining street vitality is conducive to the sustainable development of historic districts and the revitalisation of cultural heritage in cities. Less attention has been paid to how street vitality in historic districts is affected by the preservation of cultural heritage and the character of the historic environment.
Therefore, this study takes Xi'an, China, as the research object, and adopts multi-source urban data such as Baidu Wisdom to assess the spatial vitality of streets in the historic urban area, and quantifies the vitality of streets in the historic urban area, and quantifies the effects of historical cultural heritage and historical environment characteristics on street vitality. The spatial aggregation is expressed by the average activity intensity of the whole day, and the temporal stability is expressed by the activity stability index of the whole day. At the same time, a geographically weighted regression model is used to analyse the effects of historical cultural heritage and historical environment on street vitality in the historic urban area by combining POI data, street network attributes and spatial syntax indicators.
The results show that (1) the distribution of street activity intensity of working in Xi'an's historic urban area exhibits that the centre of activity intensity is mainly concentrated in the national key cultural heritage units such as the Bell Tower, the Drum Tower and the South Gate, as well as the BeiYuanMen Historic and Cultural Neighbourhood, which is dominated by a diversified mix of commerce. (2) The distribution of street activity intensity for rest in Xi'an's historic city also shows obvious spatial agglomeration, i.e., the centre of activity intensity is mainly concentrated in commercial-type streets and their surrounding areas. On rest days, dominated by leisure and consumption activities, the centres of activity are more concentrated in the commercial streets where the historical and cultural heritage is located, and the distribution of activity periods is more even. (3) The regression results show that on weekdays, street type, road integration, and density of transport facilities have a significant positive effect on the vitality of streets where historic heritage is located. However, the distance to the metro station negatively affects it. Secondly, on days off, street type, neighbourhood functional density, and density of transport facilities still have a positive effect on the vitality of streets where historic and cultural heritage resources are located. In addition, the effects of distance to metro stations are more evenly distributed on rest days compared to weekdays. Both on weekdays and rest days, the development and utilisation of historic and cultural heritage resources in the mode of functional replacement combined with organic regeneration has a significant positive impact on the vitality of the streets where they are located.
Finally, based on the above analysis, it can be concluded that the type of street where the historic cultural heritage is located, the functional density of the surrounding area, the mode of development and use of the historic cultural heritage, and the traffic organisation in the vicinity of the historic cultural heritage are the key factors determining the vitality of the street where the historic cultural heritage is located. There is no direct correlation between the distribution of the historic heritage and the vitality of the street space. This provides meaningful guidance and inspiration for vitality-oriented neighbourhood regeneration, preservation and adaptive use of historic and cultural heritage, and the cultivation of related businesses in historic districts.
