Relationship between Sediment Yield and Precipitation Intensity in Runoff Plot Based on Regression Analysis
Taking Shiniu Station in Lishui as an example,the relationship between sediment yield and rainfall intensity in runoff plot was studied based on regression analysis method.By collecting the rainfall,runoff yield and sediment yield data of 5 runoff plots in Lishui Shiniu Station in 2022,the relationship between sediment yield and sediment yield and rainfall intensity was established through regression analysis,and a conclusion was drawn:With the increase of rainfall intensity,the runoff yield and sediment yield of runoff plots also increased,showing an obvious positive correlation.In addition,the sediment yield of each runoff plot was in the order of bare land＞peach tree＞bayberry＞tea leaf＞camellia,indicating that planting can effectively store runoff and sediment,and can be used as an effective measure to prevent and control soil erosion.
