摘要介绍了测量模型次降雨侵蚀产沙量的烘干法和密度瓶法，并通过不同粒径组泥沙浑水含沙量的对比试验，验证了测量方法的可靠性。 |
| 5. | It puts forward to differentiate the coarse and fine sand and then measure the sediment yield of total precipitation erosion by using the combined method of drying and pycnometer in the light of the soil mixed with large quantity of coarser sand in the model tests
针对模型土壤中夹杂着大量粒径较粗的泥沙颗粒的试验，提出进行泥沙粗细分层，然后采用烘干法和密度瓶法相结合的方法来测量次降雨侵蚀产沙量。 |
| 6. | Ii ) runoff erosivity reflects relationship of water erosion forces and sediment yield more directly than rainfall erosivity . it intergrated ability of runoff volume and flood peak on detaching soil and transporting sediment and is more reasonable than single runoff depth or flood peak volume
( 2 )以径流侵蚀力代替降雨侵蚀力来反映水蚀营力与产沙量的关系更加直接，而且综合了径流量与洪峰在剥蚀土壤和搬运泥沙能力，比单独运用径流深或洪峰流量更加合理。 |
| 7. | In the early developing period and active developing period , the downside and middle part of the experimental watershed model are the active positions of soil erosion and sediment yield respectively , and the upside of the experimental watershed model in stable developing period of the watershed model . the main gully plays dominant role in the sediment yield process of the experimental watershed model
主沟在流域模型侵蚀产沙过程中居于主导地位，主沟的产沙量占流域模型总产沙量比例保持在48 . 7 - 66 . 6之间，在主沟的泥沙沉积量所占流域模型总泥沙沉积量的比例也保持在64 . 9 - 99 . 4之间。 |
| 8. | The gullies are formed by the processes of infiltration - interflow - collapses . ( 2 ) in the slope with sand - loess , the major factors of water erosion are the rainfall intensity and rainfall amount of annual first rainfall . ( 3 ) in the region , the evolution processes of slope gully system results from alternative actions of sand deposition and water erosion
( 1 )有片沙覆盖的斜坡小区，径流量少,但径流含沙率大，坡沟的形成过程是：垂直渗流坡地潜流崩塌； ( 2 )在沙黄土斜坡小区，每年春末夏初降雨的强度及降雨量是决定坡面产沙量的关键因素； ( 3 )该区坡沟系统的形成发育是风沙沉积、风蚀与水蚀交替作用的结果。 |
