【 摘 要 】

Erodibility is a property that results from the various properties of soils in their own structure and shows their resistance to erosive factors or their tendency to erosion. Soil properties affecting soil erodibility are significantly originated parent material. Thus, different parent materials form soils having different erodibility properties. In this study, the effects of some parent material on soil erodibility and soil properties influencing soil erodibility was investigated. The study was carried out Cemrengec Watershed within city of Kahramanmaras in Turkey. Soil characteristics such as texture, organic matter, structure, moisture equivalent and permeability, and soil erodibility indices was determined by taking samples from soils developed from limestone, sandstone, quartzite and mica schist in the watershed. Soil erodibility indices values, dispersion ratio, erosion ratio, colloidal moisture equivalent ratio, clay ratio and soil erodibility factor were calculated. So, erodibility values of soil were examined by taking 5 different erodibility indices into account. And then, whether or not there were differences among soil erodibility values was investigated. Soil properties having influence on soil erodibility indices were statistically compared by variance analysis and correlation test. According to results, soil erodibility values of parent materials ranged as sandstone>quartzite>mica schist>limestone. Besides, clay percentage was the most important soil property affecting soil erodibility taking soil properties into account.
