Wetland is a multifunctional and biodiversity ecosystem on the earth, and it is also one of the most important living environments for human beings. Large shallow lakes play an important role in providing water and maintaining ecosystem diversity in wetlands. Vegetation growing in lakes and could affect the water flow by drag force. In the paper, a two-dimensional hydrodynamic model is developed and is applied to a large shallow lake, Baihe Lake in North China and the lattice Boltzmann method is selected as the simulation approach. The water velocity field of the lake is produced by the model and the distribution of the study area is investigated. Then, the hydrodynamic characteristics of lakes under different vegetation density are studied to find its influence on the water flow. This study provides a theoretical basis through a numerical tool for the administration of local hydraulic and ecological engineering.
