| Abstract: | Methods of calculating and mapping soil erodibility (K) are introduced in this paper. Besides, a brief explanation is made of the method of setting parameters of the equation for calculating soil erodibility K value, use of the Cokriging method of ArcGIS Geostatistics in mapping soil erodibility (K), as well as application of the soil erodibility (K) map to soil erosion control, monitoring and prediction of soil losses, ecology, environment, etc. |
