摘要: 利用径流-输沙量双累积曲线与单位降雨侵蚀力输沙量(输沙量负荷)的分析表明,河龙区间泥沙变化与相关重大事件与政策密切相关。“大开荒” 时期输沙量负荷平均值最大,是输沙量负荷多年平均值的1.8倍;“大跃进”、“农业学大寨”和“文革”时期的输沙量负荷均值也较大,为输沙量负荷多年平均值的1.4~1.5倍。改革开放后,输沙量负荷下降明显,输沙量负荷平均值较改革开放前减少了55.7%,特别是在1999年实施“退耕还林(草)”后,输沙量负荷平均值下降到整个时期的最小值,仅为输沙量负荷多年平均值的33.3%。

Abstract: The analysis by using double-mass curve of cumulative runoff and sediment discharge and sediment decoupling indicator shows that, there is a significant relationship between the variation of sediment loads and correlative significant events and policies of Hekouzhen and Longmen region in the Huanghe (Yellow) River Basin.The maximum average sediment loads appeared in "Reclaiming Wastland" period,which is 1.8 times larger than the annual average sediment loads in 1951-2006.The average sediment loads are also larger in "Great Leap Forward" Movement, "Emulating Dazhai on Agriculture" and "Culture Revolution" period, which is 1.4 to 1.5 times more than the annual average sediment loads in 1951-2006 respectively.After the Chinese Reform and Opening, sediment loads decreased significantly, the average sediment loads reduced 55.7% compared to that before Reform and Opening, especially after "Grain for Green" project in 1999, the average sediment loads reached its minimum level in the whole period, which is only 33.3% of the annual average sediment loads in 1951-2006.
