| Abstract: | The paper takes the following 8 factors of rainfall erosive agent, coverage of vegetation, soil thickness, slope, soil erodibility, rock properties,unbalanced degree of population environmental capacity and proportion of sloped farmland on sloped areas as the main factor for appraising the potential danger of soil erosion. It uses the method of stratification analysis to decide the weighting of the 8 factors and appraise the potential danger of soil erosion by using ARCGIS software by different levels. The result is that the potential danger of soil erosion in Tsingtao is mainly the types of no danger, light danger and danger. The area of danger type is 636.55 km~2, only accounting for 5.74% of the area of Tsingtao. The ecological environment in Tsingtao is good. |
