我国淤泥质海岸长达2000公里,是世界淤泥质海岸分布最广的国家之一,是认识世界该类海岸沉积规律必不可少的重要组成部分。淤泥质海岸的研究能为古代同类沉积体系提供对比模式,预测若干沉积矿产的分布,具有重要的理论和实际意义。本文根据多年野外工作成果而写成,旨在对我国淤泥质海岸沉积的几个问题作初步探讨。 China’s muddy coast up to 2,000 km long, is the world’s most widely distributed silt coast of the country one of the world’s understanding of the sediment deposition is an essential part of the law. The study of the muddy coast can provide a contrasting model for similar sedimentary systems in ancient times. It is of great theoretical and practical significance to predict the distribution of some sedimentary minerals. This article was written based on the results of many years of field work, aiming at a preliminary study of several problems of sediment deposition in China’s muddy coast.
