阐明了地质景观三维建模和成因动态模拟的研究意义,分析了国内外常用三维地质建模和模拟软件用于定性地质建模和模拟的不足之处,提出了利用3DS MAX多种建模和动态模拟工具,以定性、半定量、定量地质资料和数据作为数据源,进行地质景观三维建模和成因动态模拟。以吉林省伊通国家火山地质公园为例,介绍了火山地质景观自身及其地质背景的时、空信息组织和耦合方法;阐述了火山地质景观三维建模过程中空间尺度上的大、中、小层次结构及动态模拟过程中时间段的划分方法,建立起相互联系的空间三维可视化和时间动态模型。剖析了基于3DS MAX的火山地质景观定性-半定量模型和地质演化动态模拟的可靠性、精确性及适用性。

The signification of three-dimensional（3D） model and dynamic simulation in geological scenery is set forth. The shortcomings of the domestic and international application to qualitative geological modeling and simulation are described by using 3D geological modeling software. 3DS MAX multiple models and dynamical simulation tools are put forward. 3D model and dynamic simulation of genesis in geological scenery are done with qualitative, semi-quantitative and quantitative geological data. Based on the example of 3D model and dynamic simulation of genesis in geological scenery of Yitong National Volcanic geology park of Jilin province, the methods of the space-time information organization and coupling in geological scenery are introduced. At the same time, this paper presents the structures of the volcanic geological scenery model on big, middle and small spatial scale during the 3D modeling, and the partition methods of time quantum are also clarified during the dynamic simulating. The relationship of spatial 3D visualization and temporal dynamic model is created. The authors analyzes the application, focus problem and development potential of qualitative and semi-quantitative model in geological scenery and geological evolvement dynamic simulation based on 3DS MAX.
