摘要(Abstract)：

河流水面宽度与单宽流量,是重要的水力学和沉积动力学参数;遥感技术为获取这些参数并研究其变化提供了重要的技术手段。本文以黄河三角洲河道为例,利用Landsat影像和GIS技术,结合利津站的逐日流量资料,分析了清水沟流路1976—2005年期间河道水面宽度与单宽流量的变化。研究结果显示,从空间上看,黄河三角洲河道水面宽度及其变幅由利津站向下游方向逐渐变大,而单宽流量及其变幅由利津站向下游方向逐渐变小;从时间上看,利津站下游水面宽度随时间有逐渐变小的趋势,而单宽流量随时间有逐渐变大的趋势。本文的结果可为黄河三角洲水力学与沉积动力学研究提供水面宽度与单宽流量参数,同时为黄河三角洲的治理提供参考。

关键词(KeyWords)： 黄河;三角洲;水面宽度;单宽流量;遥感监测
