摘要
ＶＲＭＬ是英文ＶｉｒｔｕａｌＲｅａｌｉｔｙＭｏｄｅｌｉｎｇＬａｎｇｕａｇｅ——虚拟现实造型语言的缩写，它能在Ｉｎｔｅｒｎｅｔ上设计并创建丰富多彩的三维动态虚拟世界。因而，它为地球科学工作者提供了一种全新的交互感应技术来模拟真实的三维地理现象。运用ＶＲＭＬ技术，在开发基于Ｗｅｂ的黑河水资源决策支持系统中进行了有益尝试，用ＶＲＭＬ２．０编写程序并结合ＧＩＳ技术，在网上显示了三维虚拟的黑河流域全景图，并且能够在各种位置、以各种视角和各种缩放比例对黑河全貌及其细节进行动态的观察和研究。文章最后对虚拟现实技术在水资源决策支持系统中的应用前景进行了展望。
VRML means Virtual Reality Modeling Language, which can design and create variou
s of animated and colorful 3 dimensional virtual models on the Internet. Theref ore, it is
providing earth scientists with a new, exciting and interactive way t o model real life
phenomena of the geographic world. In this paper, VRML is use d in the Web based decision
support system of Heihe Catchment. With the help of VRML2.0 and some GIS technologies, we
create an overall 3 dimensional virtual world of Heihe basin and display it on the Web. In
addition, the more exciting t hing is that the Heihe Catchment can be observed dynamically
under any view poin ts,any positions and any zooms. At last, we prospect more applications of
VRML t echnology in the water resource decision support system of Heihe Catchment.
