Spatial–Temporal Monitoring of Ecotonal Belt Using Landscape Ecological Indices in the Central Elburz Region: Remote Sensing and GIS Analysis

Iran has mountainous landscapes and half of its surface is occupied by highlands. Moreover, Iran is an arid country and deserts are located at lower altitudes. Most metropolitan areas are positioned in mid-altitudes between mountain and desert. Cities grow upwardly toward the highlands under pressures of urbanization and desertification. Foothill ecotones are a zone between upland mountains and...
