摘要
以西峰杨家沟小流域为研究对象,研究了在降雨和人类活动的影响下,黄土高原沟壑区小流域治理前后水沙变化。通过分析发现,治理后流域内的人类活动使年均径流量比治理以前略有增加,而年均输沙量却比治理以前大幅度减少。
The variation of water and sand is studied under the influence of the rainfall and human activity, in the fore and after management of small watershed in gully region of the loess plateau. The analysis shows that the average annual runoff volume has a little increase due to human activities after management, but the average annual sediment production has greatly decreased.
