A Study of Bioecological and Land Cover Change of Northern Lands of Khuzestan by Remote Sensing

Remote sensing is a useful technology as a superior to other methods thanks tofeatures like vast and integrated view of the area, repeatability, accessibility and highprecision of information, and saving in time. Vegetation index is extensively usednowadays in different continental, regional, and areal scales. Due to excessive use ofnatural resources, area of landscapes has been changing day to day and updating of themaps is a costly and time-consuming task. Thus, many of the well-developed countriestake benefit of satellite data at different levels. The analysed factors included 1-preparation of vegetation and land use maps of North Khuzestan; 2- assessment ofbiological potential in agriculture development of the studied area using WLC andweighted overlay technique.Based on the acquired results and performed computations, it was demonstrated thevariations in the pasture and agriculture soil during the years from 2003 to 2014 were19 percent and a significant reduction is observed in this part of land use. The changesbetween the years 2014 to 2016 were equal to approximately 11 percent according tothe computations. This value is remarkably high and indicates intensity of changesduring the recent years.
