摘要
本文给出了灌河口航空及航天图象解译结果.用航空图象分析了河口两侧岸滩的变迁过程,航天图片分析了口外泥沙的运移特征.航空图象解译结果表明,河口两侧岸线和滩线在逐年蚀退.航天卫星图象解译结果表明,河口东侧自废黄河口向西的泥沙输送趋势十分明显;河口西侧也有自西向东的泥沙流迹象,故认为灌河口泥沙输送方向是由河口东西两侧向河口运移.文中还给出了不同岸段的蚀退速率,提供了卫星和航空图片及其解译图.
This paper gives some interpretation of aerial and space photographs of Guanhe estuary. Four aerial photographs taken during 1954~1985 show that beach and coast erosion on both sides of the river mouth takes place every year. Erosion rates for different coastal sections are given. The interpretive charts of satellite photos show that there is a clear tendency of sediment transport from the Old Yellow River Mouth towards the west on the east side of the Guanhe river mouth and an indication of sediment movement from west to east on the west side. Therefore, it is concluded that sediments in the Guanhe river mouth are from both east and west sides. Aerial and satellite photos as well as their interpretive charts are presented.
