中文摘要该文通过运用铯-137法对黄土高原沟壑区陇东南小河沟老谷坡农耕地侵蚀进行研究,定量地分析了其侵蚀及产沙。结果表明:在老谷坡农地内其土壤侵蚀量很大,但其输移率却很低,即其真正流失量较小,存在大量地内堆积。通过修建梯田,可使其流失量大大减小,梯田较坡耕地拦沙效益高出96.5%。 
英文摘要 Casium-137 was uused to study soil erosion and sediment delivery on old sloping fields in Nan Xiao He gully ofeast Gan Su on loess plateau in this papery. A quantitative analysis was made to test the soil erosion and sediment de-livery. The results shown that the amount of erosion was high but delivery ratio in the slope was low.That is to say,the sediment that really lost from the land was less,so there was large amount deposition in old sloping fields. The soilloss can be reduced by constructing terrances. To compare terrance with the sloping fields,there is 96.5%benefit ofreducing sediment.
