摘　　要：该文以鄱阳湖大湖池为研究区域,采用3维建模、在多源数据融合下的场景搭建技术和动态模拟技术,对湿地复杂的生态过程变化进行3维动态模拟.以3维动态可视化的方法呈现鄱阳湖湿地的植被四季生长演替变化、季节性水位变化和不同水位与植被群落相互作用机制以及候鸟对水位和植被提供生境的响应等生态过程变化.研究结果表明:多源数据的融合是虚拟场景集成的重要基础;采用数据-模型-场景-综合动态模拟的技术为创建动态仿真场景提供有效途径;3维动态模拟技术和可视化效率优化技术结合使用可以直观有效地模拟和呈现湿地生态过程的动态变化.In this study,taking the Dahu Lake of Poyang Lake as the study area,3D modeling,scene building technology under multi-source data fusion and dynamic simulation technology are used to carry out 3D dynamic simulation 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 succession 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.
