Gradient Analysis of Urban Landscape Pattern(Case Study from Isfahan City)

Urban landscape is a heterogeneous mosaic of physical and biological patches. Quantifying landscape pattern and it's change is essential for monitoring and assessment of ecological consequences of urbanization. The recent related research has been greatly promoted by the easier availability of higher resolution remote sensing data and the development of GIS and geospatial techniques, as well as other disciplines such as landscape ecology. The convergence of GIS, remote sensing and other related disciplines has helped in quantifying, monitoring, modeling and subsequently predicting the urban land use development. many landscape metrics have been developed and widely applied for characterizing various landscape patterns in the past few decades. Gradient analysis has been used to detect the urbanization gradient of landscape pattern. In this research combining gradient analysis with landscape metrics, were used for analyzing of landscape pattern.
