文摘内容 The Holocene Yellow River Delta,with an area of 250,000km2,is one of the largest deltas in the world.This paper focuses on its coastal plain,including three younger deltas,i.e.the delta near Tianjin,the modern delta,and the abandoned delta.In the first two deltas,land subsidence,both natural and man-induced,is serious,and local sea-level rise is mainly a result of land subsidence.The major direct impacts of relative sea-level rise on the Yellow River Delta are submergence and salinity increase.As a great part of the three younger deltas is less than 2m asl,with 1m being a result of sea-level rise,the danger of submergence is great,especially during the storm surge.Low-lying coastal plain will increasingly suffer from salt water intrusion and drainage will be difficult.Decisive action is urgently required to avert or mitigate adverse effects.
