采用线性分析、多年滑动平均、Mann-Kendall 趋势检验等方法对黄河中游河龙区间1950 - 2012 年的水
沙变化特点和趋势进行了分析。结果表明: 河龙区间年际水沙变化整体呈现递减趋势,且阶段性变化趋势差
异较大; 径流量和输沙量在年内分配不均,水文站径流量和输沙量主要集中在汛期; 河龙区间年均输沙量分别
在1979 年和2000 年存在两个显著突变点。应用距平累积曲线分析表明, 1974 年后人类活动对输沙的影响显
著增强, 1975 - 2012 年人类活动总减沙量为179. 75 亿t,年均减沙量4. 73 亿t。研究结果可为流域生态和水

Other Abstract

Characteristics and variation tendency of the runoff and sediment discharge in the He-Long Reach
in 1950 - 2012 are studied by linear analysis,moving average and Mann-Kendall trend test. Results show that
water and sediment in He-Long Reach showed a significant decreasing trend,and the reducing trend was further
more in twenty-first century. The monthly distribution of the water and sediment on hydrological stations
were extremely uneven and mainly concentrated in the flood season. Annual sediment transport discharges in
the He-Long Reach existed two clear breakpoints,one was in 1999 and other was 2000. The Anomaly cumulative
curve of rainfall and sediment yield showed that the impact of human activities on sediment was significant
after 1974,the total sediment reductionby human activity in 1975 - 2012 were 179. 75 × 108 t and the annual
average sediment reduction was 4. 73 × 108 t.
