摘　　要：近年来,澜沧江-湄公河流域泥沙情势发生明显改变,对沿岸生活、生产、生态等产生了较大影响,引起了社会各界的广泛关注。从泥沙来源、入海沙量、三角洲演变趋势及三角洲变化影响因子4个方面对澜沧江-湄公河流域泥沙研究进展进行了归纳总结。结果表明,湄公河泥沙主要来源于澜沧江流域、“3S”流域和老挝北部地区,湄公河干流及三角洲来沙量均呈减少趋势,湄公河三角洲岸线变化明显,其影响因素复杂多样。在此基础上,对基础资料整理、泥沙运动物理过程、三角洲演变影响机理等需要进一步研究的方向进行了展望。In recent years,the significant change of sediment regime in the Lancang-Mekong River Basin greatly affects coastal life,production,ecology,etc.,attracting widespread attention from all fields of the society.This paper summarizes the progress on sediment research in the Lancang-Mekong River Basin from four aspects:sediment sources,sediment amount entering the sea,delta evolution trends,and impact factors of delta changes.The results indicate that sediment in the Mekong River mainly comes from the Lancang River Basin,the“3S”(Se Kong River,Se San River,and Srepok River)Basin,and northern Laos.Sediment supply from main stream and delta of the Mekong River shows a decreasing trend,and the shoreline of Mekong Delta has undergone significant changes due to complex and diverse impact factors.On this basis,we propose prospects on directions that need to be further discussed such as basic data sorting,physical processes of sediment movement,and mechanisms of delta evolution.
