Abstract
Adding limestone soil into soil body can effectively improve the performance of soil body and strengthen soil body. Thus, the study on the loss of water, soil and nutrient in limestone soil can provide data support and theoretical basis for the control of soil and water loss in mountainous areas and the control of non-point source pollution in small watershed. In this experiment, the effect of different rainfall intensity on the runoff time, runoff, sediment content and nutrient content of limestone soil is studied by taking soil in mountainous areas in Henan Province as a control through artificial simulated rainfall device. Under different rainfall intensity conditions, the runoff time of limestone soil is longer, the runoff is less, sediment and the loss nutrient content is less than that of soil in mountainous areas in Henan, indicating that limestone soil is expected to be used to prevent and control water and soil loss.
