摘　　要：应用Google Earth软件对红河三角洲地貌进行取点分析,结合区域地质、沉积背景资料详细研究红河三角洲的沉积相与沉积机制。红河三角洲发育形成典型的三角洲平原、三角洲前缘和前三角洲3层结构,三角洲平原沼泽微相发育,三角洲前缘东北部河口砂坝较为发育。将其形成模式划分为平原分流河道形成阶段、三角洲进积阶段和现代发育阶段,分析三角洲季节性沉积、高密度流体的主要特征。This paper uses Google Earth software to take langforms of the Honghe river delta,and the sedimentary facies and sedimentary model are studied combining with regional geological and deposition setting. The study shows that： the red river delta develops three layer structures including delta plain,delta front and pro delta; the marsh micro facies is developed in delta plain,and the sand bares micro facies are developed in the northeast of pro delta; the formation model can be divided into three stages including the formation of plain distributary channel stage,the delta progradation stage,modern development stage. This paper also analyzed its seasonal sedimentary and high density fluid characteristics.
