Abstract: This paper introduced the current situation of industrial heritage protection and industrial heritage under the framework of historical and cultural city protection in Fuzhou, and through the analysis of two protection practices of Fujian Mawei Shipping Administration Historical Area, Fuda Yishan Cultural and Creative Industrial Park, the issues encountered in the delineation of the protection scope of industrial heritage (core), construction activity protection control, etc., were summarized from the perspective of historical sections corresponding to the protection framework of Fuzhou's historical and cultural cities. The paper proposed reasonable methods for delineating protection scope and planning control for industrial heritage areas that are both historical sections and have cultural relics protection units, industrial heritage areas with cultural relics protection units but not historical sections, and industrial heritage areas with only historical buildings but no cultural relics protection units or historical sections. It pointed out that the solution to current problems required revision and improvement of protection documents and effective coordination with different planning.
