Based on an analysis of the types and characteristics of models for the 3-D scene of virtual irrigation districts, a description was made of the setting-up course of various models, with emphasis placed on the method of data management for different models so as to realize the real-time operation of irrigation districts. Meanwhile, an introduction was given to the information interactive way and data control procedure for the operation of the system, and an integral framework for the simple virtual reality system of irrigation districts was put forward based on a great deal of geographical data. Finally, the key technique and method for modeling of the 3-D scene for irrigation districts and process of real-time simulation and control were expounded.
