How to improve the integrity and sustainability of historic architectural complexes and their environments in modern urban planning--an example from the "Wenming Street" historic district renovation project in Kunming

Historic buildings are the bearers of human civilization. Kunming, a famous historical and cultural city in China, has numerous historical and cultural heritages and a diverse and prosperous historical and cultural background. This study takes the renovation project of the historic district of Wenming Street in Kunming as the research object and proposes a holistic, multi-dimensional, and multi-factor planning and renovation method that should focus on the district in the conservation and renovation of historic buildings through the hierarchical analysis method. Through expert scoring and weighting analysis, questionnaires, and index scores, it is found that there is a lack of "spirit of place" and insufficient expression of non-material elements in the renovation of the historic district. This study aims to realize the integration of the historic environment with the needs of modern life using a monistic logic and to provide theoretical reference and practical guidance for the conservation, renovation, and sustainable development of historic buildings and the historic environment.
