在20°和25°坡度上,选用4种雨强条件进行人工模拟降雨实验,对土壤水蚀动力过程进行了系统模拟,并运用灰色关联度的分析方法,研究了坡面侵蚀产沙量与其影响因子之间的关联程度。研究结果表明,在实验条件下,雨强与坡面降雨径流产沙量的关联度最大,水流功率次之,可以用雨强和水流功率来描述坡面径流产沙量,并建立了坡面径流产沙量与雨强和水流功率的相关关系式。
On 20 ° and 25 ° slopes, four kinds of rain conditions were selected to conduct simulated rainfall experiments. The process of soil water erosion was systematically simulated and the relationship between erosion and sediment yield and its effect was studied by using gray correlation analysis The degree of association between the factors. The results show that under the experimental conditions, the correlation between rainfall intensity and runoff and sediment yield of slope rainfall is the largest, followed by the power of water flow, rainfall runoff and current power can be used to describe runoff and sediment yield, and the slope Correlation between runoff and sediment yield and rainfall intensity and water flow power.
