本文研究了太湖湖岸、湖床的演变,湖流及湖区泥沙冲淤特性。研究表明,风浪在湖区含沙量分布上起着重要作用,而风成湖流是湖区泥沙输移的动力。本文还建立了简化的湖区泥沙冲淤模型。初步计算表明,平台山以南的沙埂系风成流沉积体。东太湖的泥沙淤积是风成流和吞吐流共同作用的结果。东太湖湖周及新淤滩地沼泽化与泥沙组成关系密切。
In this paper, the evolution of the lake bank and lakebed in Taihu Lake and the sediment erosion and deposition in the lake and lake area are studied. The research shows that storm waves play an important role in the distribution of sediment concentration in the lake area, and the wind-driven lake flow is the driving force of sediment transport in the lake area. This paper also established a simplified model of sediment erosion and sedimentation in lake area. Preliminary calculations show that the sand ridges south of Platform Mountain are aeolian sediments. Sediment deposition in East Taihu Lake is the result of the combined action of wind flow and stream flow. The swampy and sediment composition of the East Taihu Lake and the Xinjiao Beach are closely related.
