摘要

该文通过运用铯－137法对陇东黄土高源沟壑区土壤侵蚀进行研究．定量地分析了塬、坡、沟各土地利用类型的侵蚀及产沙。结果表明：通过生物及工程措施治理后的沟谷其侵蚀量都大大减小，然而塬面侵蚀问题却相对突出，塬面侵蚀量不可忽视。

Abstract

By using the method of 137Cs to study soil erosion in the loess gully area of east Gansu province

the erosion and sediment yield coming from Yuan

slope and gully are analysised quantitively.The results show that use the biological and engineering measure to control gullies

the erosion is declined

but on the surface of Yuan

it is relatively sticking out and not be ignored.
