Evaluation of cultural landscape focusing on natural heritage by integrating DEMATEL and ANP methods; Case study: Coastal Shore of Karun River in Ahvaz

The natural heritage-based cultural landscape relies on a prominent example that embodies the most distinctive natural phenomena, forms or forms, and current important ecological trends, biological evolution, and human interaction with its natural environment. Therefore, the coastal route of the Karun River in the city of Ahvaz, as a rich natural heritage, includes all the pillars and, of course, the potential of the desired cultural landscape, which unfortunately has been neglected in recent decades. In this study, with the aim of achieving the most important criteria related to the cultural-natural landscape, to create a network diagram of inter-criteria relations, weighting and normalizing them through a combined method of multi-criteria decision-making technique DEMATEL-ANP. Preliminary results of the research using the DEMATEL method show that 13 out of 23 criteria are the most important criteria of the subject. Of these, 9 are effective (positive) and 15 are affective (negative) criteria, of which 66% of the "deep interpretation of natural landscapes" cluster (2 out of 3 criteria) have positive values. It is also the most important and influential measure of "habitat value" of the "yield and productivity" cluster. According to the ANP results, although the most important criteria for the cluster are "deep interpretation of natural landscapes", but the distinction in the cluster is "performance and productivity". Finally, the findings of the limit matrix obtained from the research confirm the natural approach in the trinity (natural, man-made and man-made) in creating a natural landscape based on natural heritage in a case study of the Karun River.
