Monitoring the Landscape Changes Applying Gradient Analysis Case Study (County Behbehan)

In order to evaluate the socioeconomic and ecological functions of a city, it is essential to quantify the pattern of the land. In this regard, the use of gradient analysis is also a very effective method. Accordingly, the aim of this study is to quantify the landform of Behbahan county using the combination of land metrics and gradient analysis. For this purpose, land use changes over a period of 14 years (2000-2014) were studied. Gradient analysis for two transects in the North South and East West were designed. Both the class and landscape metrics were calculated using a moving window. The results showed that during transects, in addition to land use changes, shape and density of the patches have changed and these changes are different in the two transects. Also, the results of the analysis in both transects in the class indicate that the patch density and edge density have increased towards the city center. The results of landscape metrics based on the items show that the distribution of land in 2014, distribution of agricultural and residential land, especially land, has more distribution levels; Behbehan is the county landscape. This reflects the development of urban and agricultural land and pasture land decreased in 2014 compared to 2000 is in the region. According to the trend of metrics, it can be said that the entire north-south transect of the east-west pattern is symmetrical.
