The present study aimed to provide a conceptual framework of adaptability to the landscape approach in reusing the heritage of Abadan oil industry. This research is based on a mixed method in two phases, qualitative and quantitative. Qualitative data were collected through qualitative content analysis of written sources, case study and semi-structured interviews with 21 experts in the field of industrial heritage and landscape. Then, the data were analyzed by the grounded theory method during three stages of open, axial and selective coding and 347 open codes, 28 concepts and 9 categories were extracted. Finally, according to the codes obtained from the written sources, case study and interviews, the theory of industrial heritage adaptability to the landscape approach was presented. To validate the model resulting from this theory, the structural equation modeling approach was used using the partial least squares method in the confirmatory factor analysis phase. Quantitative findings showed that economic, cultural, social, historical, environmental, physical, technological, infrastructure, laws and policy categories have a positive and significant relationship with the adaptability to the landscape approach in reusing the heritage of Abadan oil industry. This study considers the use of landscape approach in the adaptive reuse of industrial heritage as a way to improve the quality of the eco-revelatory that by balancing the man-made environment with nature and ecological functions, it leads to stimulating a sense of appreciation for the natural environment and revealing the natural infrastructure of the city and exposing natural systems to human perception and experience.
