The Research On The Emergency Warning System Of Sudden Water Pollution Accidents Base On GIS For The Minjiang River

In this paper, the guiding ideology is to create an emergency warning system for sudden water pollution accidents of the Minjiang River which contain GIS technology, computer technology, environmental science and system science theories. We focus on the construction of the pollution simulation system of the Minjiang River.First, we establish the structure of emergency warning system for sudden water pollution accident. Then introduce the function of tow modules which are space environment management based on GIS platform and the pollution simulation system of the Minjiang River which integrated GIS.Secondly, the database for environment management based on GIS platform is overall designed.during, the programming courses, ComGIS-MapObjects was chosen as sec-development flat, Visual Basic programming language. After a long time of hard working, most enquire functions and spatial analysis functions are put in practiceFinally, base on the discussion of the hydrodynamic-quality mathematical model we used the water quality simulation program to get the initial emergency plans base on the simulation results by simulate a fictitious sudden water pollution accidents.
