作者模拟了湖泊三角洲砂体的湖退沉积过程。对实验过程中三角洲砂体的形成、主水流和三角洲砂体的迁移作了比较详细地描述；同时定量研究了不同湖水深度下洪水、中水和枯水对砂体的改造；最后尝试将湖盆内的砂体进行相带划分并进行了粒度分析。该实验主要得到如下认识：①湖水深度控制着三角洲砂体的形态和进积速率；②砂体的宽厚比可作为判断三角洲砂体形态的重要标志；③洪水对三角洲砂体的改造起决定性的作用。
The authors simulated lake retreat sedimentation processes in the lacustrine deltaic sand body. In the process of experiment, the formation of deltaic sand body, the main water flow and the migration of deltaic sand body are described in detail. At the same time, the flood, medium and low water reconstruction of sand body under different water depths are quantitatively studied. Finally, The sand bodies in the basin are divided by phase and analyzed by particle size. The main findings of this experiment are as follows: (1) The lake depth controls the shape and rate of delta sand body formation; (2) the aspect ratio of sand bodies can be used as an important indicator to judge the shape of delta sand body; (3) the flood decisive for the delta sand body reconstruction effect.
