伊洛河流域降雨与植被类型对产流产沙的交互影响研究
Interactive Effects of Rainfall and Vegetation Types on Runoff and Sediment Yield in the Yiluo River Basin
摘要
Abstract
In order to investigate the interactive effects of vegetation type and rainfall characteristics on slope runoff and sediment yield processes,this study was conducted based on field-measured data.Methods such as K-means clustering were employed to analyze the rainfall,runoff and sedi-ment yield characteristics of bare land,agricultural land,and forested area in the Hugou small watershed of the Yiluo River from 2019 to 2024.Fur-thermore,the benefits of runoff and sediment reduction were analyzed.The results show that:the runoff depth and soil erosion in bare land plots are greater than that in agricultural land and the smallest is in forest land during each rainfall event.Under short-duration and high-intensity heavy rain-fall,sediment yield from bare land is five times greater than under medium-to-long duration and low-intensity rainstorms,making it the rainfall type that produces the highest sediment yield.Long-duration and low-intensity heavy rainfall is more conducive to runoff generation,while forestland ex-hibits the lowest soil loss.Among all rainfall types,forested areas consistently demonstrate greater runoff and sediment reduction benefits than agri-cultural lands.Runoff depth in bare land and agricultural areas shows a significant positive correlation with rainfall,while forested areas exhibits a highly significant positive correlation between runoff depth and rainfall.Soil erosion amount across vegetation types shows a significant positive cor-relation with rainfall intensity.Runoff depth on bare land and cropland exhibits an exponential relationship with soil erosion amount,while runoff depth on forested land demonstrates a polynomial relationship with soil erosion amount.关键词
