摘    要:本项目研究了黄河口近半个世纪径流量与输沙量的变化,廿世纪五十年代至九十年代水、沙量呈明显递减,预测今后廿年黄河口多年平均径流量不会超过150~200×108m3,多年平均输沙量不超过5~7×108t.在研究黄河三角洲海岸线历史变化的基础上,结合预测的水、沙量,用地貌模拟法预测了今后廿年黄河三角洲0m海岸线的基本走向.

关 键 词:径流量  输沙量  海岸线  变化  预测  黄河口  模拟

Abstract:This study analyzes the changes of the runoff and sediment discharge during the past half century of the Yellow River Estuary. From the 1950s to the 1990s, the runoff and the sediment discharge showed an obvious progressive decrease. It is predicted that, in the next 20 years, the average runoff per year will mot be more than. 15-20 billion m3, and the average sediment discharge Per year will be less than 0.5-0.7 billion tons. On the basis of studying the historical changes of the coastline of the Yellow River Delta and in the light of the predicted runoff and Sediment discharge, the general trend of the 0 m coastline in the coming 20 years is predicted by means of geomophological simulation.
Keywords:Runoff  sediment discharge  coastline  change  prediction
