摘要: Connectivity of potential habitat patches has become essential for the biodiversity conservation and protection. In Multi Criteria Evaluation (MCE) IDRISI software, Weighted Linear Combination (WLC) module facilitates to choose connectivity analysis mainly based on weights given through Analytical Hierarchy Process (AHP) method. Digital Elevation Model, Slope, Disturbance Index layer, Road natural vegetation layers are different parameters considered WLC along with Biologcial Richness Layer. AHP results showed 0.05 consistency ratio. generated outputs applied in graph theory Conefor Sensinode 2.6 software. Integral (IIC) special emphasis each habitat’s importance value (dIIC: patch comparison all entire study area network approach) analyzed understand connectivity. Perspective component chosen dIIC served huge amount information regarding further intensive field analysis. Spatial analyst tools ArcGIS helped find paths between source destination. The two from layer passed identified (A, B, C D). Thus, these methods played important role maintenance patches. Decision support WLC, coupled facilitated identify corresponding path efficiently.
