Analysis of the function of topographical characteristics in land use of Galougah region using GIS & RS

Land use without considering the topographical characteristics of the area leads to horrible consequences such as soil erosion, desertification, and natural resources degradation. This research which has been done in the area of Galougah in the eastern part of Mazandaran province aims at determining the role of topography factor on land use, in small section of the city( 19,603 Hectares) via geographical information system and remote sensing data. For better classification of satellite images in order to design the map of land use, have been applied Maximum Likelihood Procedure which is a suitable and precise method in this area. Distribution and the area of different land use including human building lands, agricultural lands, gardens, pastures, overgrown and sparse jungles, perpetual water resources, sandy and stony lands, have been determined using Arc view software. The land systems map based on land use map and slope and hypsometry maps have been prepared. The results of this research showed that in the studied area, agricultural lands and overgrown jungles cover almost 95% of the area and 3. 7% of the area square are allocated to other human usages that 90% of this land use is settled in flat plain with its altitude of lower than 200 meters. Therefore three major usages are settled according to the topographical region. Key words: Land use, Topographical features, Galougah, GIS, Remote sensing.
