根据小浪底、花园口、黑石关3个水文站近50 a实测径流量与输沙量数据资料,运用交叉小波分析方法,结合交叉小波能量谱、小波凝聚谱和小波功率谱探讨了尹洛河水沙入汇对黄河干流下游水沙的影响.结果表明:①黑石关与小浪底径流量在1978-1992年间均具有4~9 a的周期尺度;黑石关站输沙量和小浪底站输沙量相关性不显著;②黑石关径流量对花园口径流量有持续稳定的影响,主要体现在1965-1996年的0~9 a的周期尺度上;黑石关输沙量对花园口输沙量有一定影响,主要表现在1958-1970年的4~10 a和1956-1962年的0~6 a的周期尺度上,但影响程度不大.总体而言,伊洛河水沙入汇对黄河下游径流过程影响显著,输沙过程影响不大.
A Study of the Effect of Yiluo River on the Flow and Sediment of the Yellow River
According to Xiaolangdi,Huayuankou and Heishiguan Hydrologic Station of measured net flow and sediment transport data in recent 50 years, cross wavelet analysis method, combined with cross wavelet energy spectrum,wavelet spectrum and wavelet power spectrum to investigate the impact of exchange rate to the river Yiluo sediment into the Yellow River of water and sand.The results show that Heishiguan and Xiaolangdi Dam had 4~9 years'' scale periods in 1978-1992.Dam sediment did not related.Heishiguan runoff has the strongest effect on Huayuankou which are mainly concentrated in the main period of 0~9 years in 1965-1996, Heishiguan has a sustained, stable effect on Huayuankou bore flow.Heishiguan sediment runoff has the strongest effect on Huanyuankou which are mainly concentrated in the main period of 4~10 years in 1958-1970 and 0~6 years in 1956-1962, Heishiguan sediment has a certain effect on Huayuankou, but the overall impact is not.Yiluo River runoff inflow has a significant effect on the Yellow River, but the sediment has the little impact on the Yellow River.
