本文针对不同地区水文地质参数 -电阻率预测模型的不定性 ,给出了 4种可供选择的预测模型 ,并在计算机上实现了最佳预测模型自动选取及水文参数的预测计算。针对地球物理工作者勘探地下水时 ,由已知预测未知的类比思维方法 ,根据波谱分析理论 ,建立了电测深数据相关预测的数学模型 ,并研制了有关软件 ,结果表明 ,应用本文所建立的预测模型 ,可取得显著效果 According to the uncertainty of hydrogeological parameter-resistivity prediction model in different regions, four kinds of prediction models are given, and the best prediction model is selected automatically and the prediction of hydrological parameters is realized by computer. According to the spectrum analysis theory, the mathematical model of electric sounding data correlation prediction is established and the software is developed based on the analogy thinking method of unknown prediction. When the geophysical workers explore groundwater, Predictive model can achieve remarkable results
