Environmental evaluation with land ecology and landscape ecological approaches: case study of Kaleibar Chay, basin, Arasbaran, Iran

This research attempted to find the best sites for development with ecosystemic and landscape ecological approaches. For this purpose, the case study was evaluated by each approach. After data collecting, quantity and quality criteria of the case study zone were quantified and became dimensionless and thereafter limitation layers based on Boolean logic were applied to the map and each approach. Regarding consistency matrices and acceptable errors and using analytical hierarchy process (AHP) principles and aggregative support system, criteria weights in every approach were figured out. Finally, using simple additive weighting (SAW) method, criteria were weighted in each approach. For development, the worked out results were sorted in four groups from high preference to low and then consequences were represented in one complex map and matrix. The complex map outcomes were confirmed by matrix diameter selection which was recommended in every approach. The results showed 985. hectare appropriate areas out of 587. hectares for basin development. In each approach, the most overlap was observed in the lowest preference.
