To protect industrial cultural heritage, the methods of overall protection and utilization of industrial heritage were put forward in the transformation and development of resource-based cities. Taking Chongqing, a famous old industrial city in China, as the research object, from the cultural heritage, history, architecture, urban planning and other disciplines, the construction of Chongqing industrial heritage protection theory and practice methods were explored to guide the protection and utilization of Chongqing industrial heritage. A progressive evaluation method from the whole to the local was established. Industrial cities, typical corporate and architectural heritage were evaluated. The overall characteristics of urban industrial development were reflected. The renewal of old industrial areas and the protection of industrial heritage were elaborated through the overall co-ordination of urban design and detailed planning. The results showed that it was the key to integrate the protection elements and requirements into the detailed urban control planning. Therefore, special planning plays an important role in protecting industrial heritage.
