Abstract

In natural ecosystems, monitoring has a special issue for the optimum use of these ecosystems. Urmia Lake is the largest international wetland of Iran, and also the environmental characteristics have caused Urmia Lake as a more of attractive to researchers and planners. Recently, fluctuation in the level and volume of the Lake water has been caused many scientists to attract to discus and research about these subjects. In this study, we carried out to detection about the STRUCTURAL CHANGE of URMIA WETLAND by using REMOTE SENSING, GIS, as well as Landscape Ecology Science in lastly 21 years time to accomplish an environmental management for the wetland in 2012. Hence, firstly we prepared the imagery of Landsat 4 and 5 and TM imagery related to the four time periods, then, we used the ENVI software for the geometry and spectral corrections, and finally, images were categorized into two classes for quantitative calculating about wetland change: blue and non-blue images. By using the FRAGSTATS software, the metrics of the landscape for quantitatively about STRUCTURAL CHANGE were made. The area of the Urmia Lake by results from CA metric was observed decreasing. Furthermore, the amount of the PD metric from 1998 to 2006 has increased and in 2011, this amount showed 300% increased. The amount of the TE metric from 1990 to 1998 has been increased, and in 2006 and 2011 this amount significantly decreased. The amount of the MESH metric from 1990 to 1998 has been increased and from 1998 to 2006 as well as 2011 this amount was decreased. The amount of the ED metric from 1990 to 1998 was decreased but in 2006 and 2011 increased. The amount of the LPI into 1990, 1998, and 2006 was constant, but in 2011 this amount was significantly decreased.
