| 摘 要： | 为了充分表达青藏高原岩石圈演化，根据亚东－格尔木地学断面图所提供的重力异常资料，结合断面域的磁测资料、地震、大地电磁、大地热流和综合解释等资料的基础上，利用GM－SYS反演软件进行精细断面反演得到断面域地下结构，进而构建现代岩石圈三维结构模型。研究在详细收集研究近二十多年来青藏高原形成和隆升模型的基础上，以Sun-Lin Chung、Mei-Fei Chu提出的青藏高原构造动力学模型和Wang Zejiu, Wu Gongjian, Xiao Xuchang在“GLOBAL GEOSCIENCE TRANSECT GOLMUD-EJIN TRANSECT, CHINA”提出的青藏高原大陆板块漂移的动力模型为基础，构建不同地质时代断面域可能的岩石圈三维结构模型，并以之为描述断面域构造演化的关键帧。以OpenGL&VC++.NET作为软件开发平台，研制了虚拟现实表达系统软件，通过计算得到关键帧之间的中间帧。根据不同地质年代中断面构造演化的具体过程，以时间序为准即时演算得到反映整个构造演化史的三维过程，最终实现亚东－格尔木地学断面构造演化历史的动态虚拟现实可视化表达来再现青藏高原岩石圈演化和动力学过程。 |

| Abstract： | In order to visualized present the Qinghai-Tibet plateau lithosphere evolution, the virtual reality (VR) technique was used to study the Yadong-Golmud geosciences transect. Combined with the integrated geophysical and geological interpretation cross section results offered by ‘YADONG-GOLMUD GEOSCIENCE TRANSECT’, compiled by Gongjian Wu etc., the modern plateau three dimensional lithosphere structure along the transect was inversed by the transect gravity anomalies. Based on the “Tibetan tectonic evolution inferred from spatial and temporal variations in post-collisional magmatism” by Sun-Lin Chung, Mei-Fei Chu, etc., and “Global geoscience transect Golmud-Ejin Qi transect, China” by Wang Zejiu, Wu Gongjian, Xiao Xuchang etc., the lithosphere structure of different geological time in plateau and the dynamic evolution models were established. These models make up of key frames of the evolution history in Qinghai-Tibet plateau. According to the evolution process in geological time, the middle frames between two key frames were calculated to make the visual display become smoothly. After the VR software tool kits was developed under OpenGL & VC++.NET platform, It was used to display the dynamic evolution of Yadong-Golmud geoscience transect. |
