Study On Model Calculation Parameters Automatically Extraction Technology By Pore Ground-Water Flow Visualization Value Simulation

The problem of Ground-Water resources is one core problem of water resources at present. Evaluating Ground-Water resources accurately is the key to utilizing water resources rationally. And numerical simulation of Ground-Water is one principal method of Ground-Water resources evaluation. Currently, in the most Ground-Water flow numerical simulation, the assignment of the calculation parameters is manual, so the simulation cycle is long, low efficiency and computational parameters need to be solved urgently in the automatic assignment problem, improve the efficiency of Ground-Water flow numerical simulation.Based on the theory of the theoretical hydrogeology, geographic information science and computer science, analysed the existing research, the paper focuses on the extracted technology of the simulation parameters, Using GIS’s spatial analysis function and combining the model parameters, then achieves spatial distribution parameters automatic extraction and improves Ground-Water flow numerical simulation’s efficiency. The paper’s the main content is:(1) study the physical meaning and space distribution features of parameters which is needed in pore Ground-Water flow numerical simulation, classifies the parameters into point, line, surface, three spatial distribution parameters types according to spatial distribution characteristics.(2) Based on studying the concept model of Pore Ground-Water flow simulation concept model,Combining the model parameters, the paper builds the spatial data model based on Geographic Information System’s pore Ground-Water flow numerical simulation.(3) Using GIS’s spatial analysis function, this paper studies on the technological courses that the parameters are automatically distilled. Combining those parameters data file structure related to Ground-Water flow finite element numerical simulation, the article automatically generates the data files.Finally, in order to verify the key technologies’validity, the article choose Yancheng, Jiangsu Province as simulated domain, use the developed system to realize automatic withdrawal of pore Ground-Water flow numerical modeling’s parameters, and verify these extracted parameters. It has good simulating effect, can provide spatial assistant decision support to Ground-Water’s reasonable exploitation in Yancheng.
