| Abstract: | The soil erodibility ( K) value in this region was investigated with the formula calculation method, based on the physical and chemical properties of soil and soil map of the soil survey. In this study, a K value map well registered with the topographic map was made, in which accurate geographic positions could be located. Meanwhile, applications of the K value map in soil and water conservation, monitoring of soil loss, ecological agricultural construction and reducing floods were also discussed. |
| Keywords: | Soil erodibility ( K ) Map of K value Monitoring annual soil losses |
