- Abstract
With the expansion of production and construction projects in recent years, water and soil erosion in the southern mountain area of Ji'nan has been increased significantly. In order to protect the important supply area of Ji'nan spring water, it is necessary to study the characteristics of soil and water loss and its control measures in the southern mountainous areas. Based on the runoff and sediment data of the runoff plots in Jixi Soil and Water Conservation Monitoring Experiment Station, soil erosion characteristic under the different slope were analyzed combined with the rainfall, soil and vegetation factors. The study showed that: (1) the runoff depth and soil erosion increased with the increase of slope gradient, the maximum value appeared at 20~25 degrees slope; (2) The mean value of runoff depth in different slope was obviously correlated with rainfall intensity, the runoff depth increased with the increase of rainfall intensity; Soil erosion quantity is affected by the surface vegetation and soil characteristics besides rainfall characteristics, it increased with the increase of rainfall intensity and decreased with the increase of vegetation coverage. And the degree of soil and water loss of slope can obviously weaken by carrying out the vegetation measures.
