In order to investigate the composition of particle size of surface sediments in shallow lakes, the response of particle size distribution to the source and hydrodynamic characteristics of sediments, and the distribution characteristics of nutrients in sediments of shallow lakes, the particle size of sediment samples from four shallow lakes with different sizes and shapes in the Lixiahe Region were studied. The results are as follows: (a)The average particle size of the surface sediments in the study area decreases with the increase of depth. (b)The vertical distribution of the median grain diameter of the surface sediments in large lakes is significantly different. (c)The transportation capacity for sands of large and wide lakes is stronger than that of small and narrow lakes. (d)For a large lake, the sand content in the central area is higher than in the surrounding area of the lake. (e)The triangular distribution chart of particle size shows that the surface sediments mostly fall into the categories of silt loam and sandy loam, indicating that the hydrodynamic activity of the lakes in the study area is strong. (f)Poor continuity in the vertical distribution of sediments occurs in Jiulongkou Lake with a large amount of wind disturbance. (g)The vertical distribution of the average particle size of sediments in Wugong Lake and Desheng Lake does not change significantly, indicating that hydrodynamic conditions rarely change. These results agree with the field investigations.
