摘要
有关黄土高原水土保持对地表水资源的影响在近10多年来受到普遍关注。分析了主要水土保持措施,如林草措施、基本农田和沟道工程措施的水文效应及其对水资源的影响。预测到2050年黄土高原完成了各项水土保持治理任务后,每年减少入黄泥沙7～8亿t,减少径流量60亿m3以上。
In recent 10 years,the effects of soil and water conservation on surface water resource were paid more attention on the Loess Plateau.The author analyzed hydrological effects of principal soil and water conservation measures,including forest and grass,basic farmland and channel engineering measures,and impacts of these measures on surface water resources.In 2050,it is estimated that after soil and water conservation planning is completely implemented on the Loess Plateau,sediment yield in the Yellow River will reduced by 0.7～0.8 billion tons,runoff volume will decreased by 6 billion cubic meters.
