The Three-Dimensional Dynamic Visualization Simulation Method for Ecological Processes in Poyang Lake Wetland
In this study,taking the Dahu Lake of Poyang Lake as the study area,3D modeling,scene building tech-nology under multi-source data fusion and dynamic simulation technology are used to carry out 3D dynamic simula-tion on the changes of complex ecological processes in the wetland.The three-dimensional dynamic visualization method is used to present the dynamic changes of the ecological processes such as the vegetation growth and succes-sion changes in Poyang Lake wetland in four seasons,the seasonal water level changes and the mechanism of interaction between different water levels and vegetation communities,as well as the response of migratory birds to the water level and the habitat provided by the vegetation.The results show that the fusion of multi-source data is an important foundation for the integration of virtual scenes,the use of data-model-scene-integrated dynamic simulation technology provides an effective way to create dynamic simulation scenarios,the combination of three-dimensional dynamic simulation technology and visualization efficiency optimization technology can intuitively and efficiently simulate and present the dynamic changes of the ecological process of wetlands.
