Abstract Under the background of global urban stock updating and in-depth adjustment of industrial structure, the decline of traditional industry has spawned a large number of industrial heritage sites. Due to topographic constraints, hydrological impact, and ecological sensitivity, the types of mountainous waterfront face multiple contradictions that have become the key difficult points in the field of industrial heritage protection, such as: “serious spatial fragmentation,” “complex ecological restoration,” “fragmentation of cultural heritage,” and “difficult function adaptation.” Taking the industrial heritage of the Chongqing Power Plant area as the research object, this paper uses the technical method of “field research+GIS spatial analysis” to build a multidimensional status diagnosis system covering terrain, transportation, ecology, function, and other aspects, and accurately identify the spatial characteristics and existing problems of 35 core heritage elements in the area. The analytic hierarchy process is used to establish a three-level value evaluation system of “target level–criteria level–indicator level” and 20 experts in relevant fields are invited to assign values. The consistency test (CR 0.1) ensures that the evaluation results are reliable. Finally, the evaluation conclusion is quantified with historical value (weight, 0.346) and cultural value (weight, 0.184) as the core value dimensions. At the same time, the core trade-offs between tourism development and habitat restoration, energy utilization, and heritage protection are considered, and the policy adaptation, governance mechanism, and economic feasibility are analyzed. Based on the current situation diagnosis and value quantification results, targeted renewal and reconstruction strategies are proposed from the five levels of architecture, culture, ecology, transportation, and function. A “four level classified transformation mode” is formed at the architectural level; a “terrain hydrology vegetation” collaborative restoration system is constructed at the ecological level; a “three-dimensional slow traffic network” is planned at the transportation level; and five characteristic groups are divided at the functional level. The implementation effect of the strategy is verified quantitatively through GIS spatial simulation, ecological benefit quantification model, traffic accessibility measurement, and other technical means. The results show that the traffic accessibility in the area is increased by 30%, the green space rate is increased to 39%, the annual carbon sequestration is up to 19 200 kg CO₂, and the bird species in the waterfront area are increased by 20%, realizing the dynamic balance between heritage protection and urban development. The key findings of the study include the following: (i) the renewal of mountain waterfront industrial heritage needs to establish a three-dimensional logic of “value quantification–trade-off adaptation–feasible landing”; (ii) terrain adaptability and cultural locality are the core pain points of transformation; (iii) multiple governance and revenue feedback mechanisms can improve the sustainability of the project. Through the innovative methodology of “spatial visualization+value quantification,” this study provides a reproducible technical framework and practical samples for the renewal of industrial heritage in mountainous waterfront areas. The relevant strategies have been verified by GIS simulation that the accessibility has been improved by 30% and the green space rate has been increased to 39%.
