复杂河流系统水污染的计算机图形模拟

讨论在河流系统水污染规划中应用交互式计算机图形技术。通过对复杂河流系统水污染的图形模拟，提出建立图模型的一般理论和方法，并就浑太流域河流水污染案例给出实际模拟结果。

WATER POLLUTION SIMULATING OVER A RIVER BASIN USING COMPUTER GRAPHIC MODEL

A Computer Graphic Model(CGM) was realized on personal computer for the purpose of river water pollution simulating and planning.With the aid of common software AutoCAD,a color map of complex river system was established and a suit of graphic symbol block such as pollution source,water intake,wastewater treatment plant etc.was designed to fit the needs of basin pollution management and planning.A person can insert,move/remove or modify these symbol blocks in the CGM of river basin freely.While a new idea is confirmed,a simulation program POLSIM(written With AutoLISP) can be started which redraws the river with different width and color by mean flow quantity and water quality.The result of a case study and a group of photograph was presented.The methodology of CGM makes the planning process of basin water pollution control easier,visual and interactive.CGM is a good tool to link the decision maker,planner and system analyst with active graphic.
