| 摘 要： | 采用多坡段组合模型,通过室内人工模拟降雨实验,初步研究坡沟系统中片蚀、细沟侵蚀、浅沟及切沟侵蚀的水力、泥沙参数变化及其相互间的关系,以雷诺数、弗劳德数及过水断面单位能量为不同侵蚀方式发生的动力临界指标,初步得出不同侵蚀方式发生的水动力临界值,对揭示坡沟系统土壤侵蚀规律和产沙预报具有重要意义。 |

| Abstract: | In the slope-gully system in the Loess region of hills and gullies, erosion types and shapes are arrayed regularly in the vertical direction, which forms the characteristic of vertical distribution diversity of the erosion types. Based on the artificially simulated rainfall experiment, sheet erosion and rill erosion in the slope-gully system, the dissimilarities and relations among the hydraulic and sediment parameters and the dynamic criticalities at which various types of erosion happen, are studied preliminarily in this paper, which is of great significance to discovering the rules of soil erosion and forecasting the sediment production. |
| Keywords: | soil erosion chain erosion pattem hydraulic characteristic Loess region of hills |
