Abstract

As a result of misuse of agricultural lands in the Aegean Subregion (Turkey), which is prominent with its productive agricultural lands and agricultural product variety, the natural yield capacity of the land has decreased considerably and VIII. class areas were occurred where parent material partly exposed. In this situation the most important factor is erosion. In this study, the natural environment properties of the Aegean Subregion was determined with Geographical Information Systems and Remote Sensing Methods then the erosion risk of the study area was determined with ICONA (Institut National Pour la Conservation de la Nature) method. In the second stage, the methods and analyze results used in previous erosion studies compared with the results determined by ICONA method. The most important result of this study is that; in areas where the vegetation cover is high, the risk of erosion is low; but rather, it is determined that there is more erosion risk in the areas where vegetation cover is low due to destruction. Furthermore by determining erosion risk with ICONA method; it come out that vegetation cover density is more effective than other factors (slope, lithology and etc.)
