Analysis of the Water and Soil Erosion and Infiltration Characteristic in Ziquejie Terrace

The natural gravity irrigation in Ziquejie Terrace has gotten the wide attention of many water conservancy scholars for a long time. Considering the vegetation in the study area, farming, topography, rainfall equipment and representative and other factors in this paper, several typical parcels were selected to set runoff plots (P1, P2, P3). Analyzed the runoff time, ratio of the runoff and sediment yield, infiltration rate, soil infiltration, the process of runoff and sediment yield and the relationship between runoff and sediment yield under different precipitation intensity in three test plots by simulated rainfall experiment, and reveal the influence principle of Rainfall intensity, gradient, vegetation, soil properties and other factors to slope infiltration, runoff and sediment yield, Provide a theoretical basis of soil and water conservation, organization and management work in Ziquejie Terrace.
