Abstract:Soil erodibility is an important indicator to evaluate soil susceptibility to erosion,and an important parameter in soil erosion prediction.A study was carried out on the issue of soil erodibility values of different soil erosion regions in China using the data obtained from field observation of plots.A set of soil erodibility values were calculated using field data,and used to analyze feasibility of estimating erodibility of the soils in China.Results show that the soil erodibility estimation models now available from other countries could not be used directly in estimating soil erodibility in China,but there was a fine linear relationship between estimated values and measured values,though the former were obviously higher than the latter.A new method is advanced for estimating soil erodibility of the soils in China despite of difference in geographic region and availability of data.The results of the research could be directly used in prediction of soil erosion in China.
