  The problem of black soil degradation is serious in the northeast of China. The aim of the present work is to evaluate the black soil loss due to water erosion in the 228,030 ha area of Ashihe river. The 20 years data, including daily climate data, detailed soil and land use map, are used as the soil and water assessment tool input data to analyze the black soil loss quantitatively in the specific area.
