The fitting formula could be used to analyze the Q - sw relationship between exploratory hole qualitatively and quanlitatively, reduce the influence of error factor and improve the credibility of the flow prediction, and provide a reliable scientific and rational basis for the project. The whole process can be worked effectively, and have certain value in the water - supply and hydrological surveys. Key W ords:pumping test, flow prediction, curve fitting, least square method and numerical analysiswith MATLAB 0
