- Title:
- Effects of Different Controlling Measurements on Runoff and Quantity of Silt in Small Watersheds
- 摘要:
- 为了探索黄土丘陵沟壑区不同治理措施对产流产沙的影响，选择了有代表性、沟道走向一致、峁坡沟坡地貌类型相近的四条小流域为研究对象，以工程措施、生物兼小型工程治理和植被自然恢复的牧荒生物沟与不加任何生物措施和工程措施以传统农耕方式的对比沟作治理效益对照，设死坝进行年降雨侵蚀监测。3年实测证明；工程沟、生物兼简易工程沟、牧荒生物沟与对照沟减沙比分别为63%、24.3%和43.6%，初步看出趋势为生物兼简易工程沟治理效果最好，工程沟次之，自然植被恢复的生物沟最差。
- Abstract:
- In order to study the effects of different controlling ways on runoff and quantity of silt in small watershed with the same treatments on the slope lands of gullies and hills, some certain gullies were tested. The treatments are as follows: (1) the gully was controlled by engineer; (2) the gully was controlled by plants cover and simple engineer; (3) the gully was controlled by the natural vegetation; and (4) the troditional tillage as the check. The annual erosion by rainfall was determined in the died-dam.The data for three years was proved: the ratio of amount of silt for treatment (1), (2)and(3)to(4)was 63.1%, 74.3% and 43.6% respectively. The preliminary conclution was that the treatment (1)was the best one, the treatment (2) was the second and the treatment (3) was the last.
