| 摘 要： | 根据利津站1950-2003年的水、沙实测资料,采用水文学和数理统计学相结合方法,对黄河入海水沙通量进行分析,分别得出了水、沙通量的年代变化、年际变化、季节变化规律以及水、沙通量之间关系.结果表明：黄河入海水、沙通量递减趋势明显,尤其在近20a来这种趋势更加显著;年际、年内沙量变化幅度都大于水量;黄河入海水沙主要集中在汛期,汛期与非汛期的水沙量差异将会持续减小;年输沙量和年径流量、多年平均月输沙量和径流量分别以乘幂、多项式回归,各月多年输沙量和径流量以多项式、指数回归,相关性都很高.

| Abstract: | According to the measured data of runoff and sediment at the Lijin hydrological station in the period from 1950 to 2003, the multi-method of hydrology and statistics is applied to study the decadal, yearly and seasonal variations in water and sediment fluxes to the estuary and their relationship.The result shows that : ( 1 ) the water and sediment fluxes decreased apparently, especially the sediment flux in the last 20 years ; ( 2 ) the amount of water and sediment in the flood season plays a very important role in the whole year ,but this trend will weaken in the future; and ( 3 ) there is a relatively good correlation between water and sediment fluxes, which is proved by different regressive equations. |
