| 对昌吉州历年灌溉周期内机电井的水、电使用大数据记录，通过数据清洗，挖掘其中有价值的数据，确定单井水电系数、实际功率、实际流量等参数。通过多项式回归的方法拟合水电系数与这些参数的关系。分析得出水电系数的合理范围，为平台准确计量用水量提供支撑。结合乡镇平均水电系数和实际功率，得到了乡镇水电系数的参考值表，建立水电系数水泵实际功率、实际流量的关系模型，通过参数优化，确定了拟合水电系数与水泵实际功率、实际流量关系模型，模型预测值与实际值的均方差为0.029，决定系数0.944，预测错误率为0。通过以上工作，为昌吉州地下水开采量的校核提供支持。 |

| Abstract: |
| For the big data records of water and electricity use of electromechanical wells in Changji Prefecture over the years in the irrigation cycle, through data cleaning, mining the valuable data, and determining the single well hydropower coefficient, actual power, actual flow and other parameters. The polynomial regression method is used to fit the relationship between the hydropower coefficient and these parameters. The reasonable range of the hydropower coefficient is analyzed to provide support for the platform to accurately measure water consumption. Combined with the average hydropower coefficient and actual power of villages and towns, the reference value table of the hydropower coefficient of villages and towns is obtained, and the relationship model between the actual power and actual flow of the hydropower coefficient pump is established. Through parameter optimization, the relationship model between the fitting hydropower coefficient and the actual power and actual flow of the pump is determined. The mean square deviation between the predicted value of the model and the actual value is 0.029, the decision coefficient is 0.944, and the prediction error rate is 0. Through the above work, it provides support for the verification of groundwater exploitation in Changji Prefecture. |
