The Application Of Genetic Algorithms On Water Pollution Control Planning Of Geographical Information Systerm

Geographical Information System (GIS) is a major measure of spatial data management and analysis; however, it can't automatically mine various potential spatial pattern, spatial data, and combined with the powerful GIS ability of spatial analysis and manipulation to mine connotative and potential spatial characteristic and spatial pattern from a vast of non-structured spatial data, finally serviced for scientific research and spatial decision.Water Pollution Control Planning included different factor of society,economic, resource etc. And between these factors have the complex mutual function. face to those complex objects ,it is difficult to guarantee the environment, the economical, the society coordinated development if Only depends on policy-maker's experience and the knowledge. So it is obvious that system analysis and the system optimization are the powerful tool of water pollution control plan. The main characteristics of water pollution control plan decision system based on the model algorithm realization problem analysis and the decision-making, it solves the water pollution control plan problem with the geography information technology and the systems science method, It is the information technology in the water pollution control plan domain application, it is behalf of water pollution control plan development.The present paper attempt to inserts the model algorithm mode algorithm to the GIS decision-making support program closely. Thus in data acquisition relatively prepared situation, it has saved the massive water pollution control plan analogue result and the experiment. So it is solve the actual problem to bring the convenient effective way, Has a better practical value.This paper was divided in to six chapters as follows: the first chapter, has mainly outlined the Genetic Algorithms theory and the technology and its the present research situation, Summary tradition water pollution control plan method and so on. The second chapter introduced the water quality present situational appraisal and the water pollution load research. The third chapter: Water pollution control plan correlation essential parameter and determination. The fourth chapter, Water pollution control decision-making support program concrete realization. The fifth chapter, take the second Song hua River as the basin example research and the confirmation. Sixth chapter: The conclusion, carried on the summary to the full text, And proposed the deficiency.
