Özet (Çeviri)
Qualitative and Quantitative Determination of Soil Erosion in Different Land Use Types and Slope Conditions with a Comparation of the Results of USLE Simulation Model (Universal Soil Loss Equation) in Behind of the Black Sea Region in Gümüşhane City The research took in three different land use types (Scotch pine forest, pastural land and agricultural land) and in two different slope classes (15-20 %, 35-40 %) place. Within six measurement stations (for each land use type and slope class station) totally eighteen measurement plots have been constituted. Soil loss and runoff measurements have been investigated in these eighteen plots during three years and in monthly periods. A rain gauge for the rain measurements have been installed in the research area. Soil erosion and runoff amounts determination in different land use and slope conditions was the main goal of this research. In addition to this nitrogen (N), phosphorus (P) and potassium (K) plant nutrient substances have been measured in the soil samples. Also the USLE simulation model had been applied in the research area. The results pointed out that the soil erosion amounts in each land use type and slope degree which measured in the research plots are quite less than the calculated results of the USLE simulation model. Measured average soil loss amounts in agricultural land and in pastural land are almost the same (0,18 tone/hectare/year). Soil loss amounts for each land use Types are in 35-40 % slope class the most (0,16 tone/hectare/year in pastural land and 0,12 tone/hectare/year in agricultural land). The measured soil loss amounts in the yellow pine forests are almost zero.
