根据实测的地磁数据，提出一种基于泰勒多项式在超小尺度下的地磁正常场的模型建立方式，结合数据处理﹑最小二乘拟合法，利用泰勒多项式模型建立超小尺度下的地磁正常场，并绘制相应的局部地磁图。经实验证明，超小尺度下的泰勒多项式地磁模型能够相对精确的描绘地磁正常场的分布。这为建立超小尺度地磁模型提供了参考，也可为小尺度内测量磁异常提供可靠的参考场。

Based on geomagnetic surveys , super-small scale geomagnetic normal field model-ing method using Taylor polynomial was proposed .Combined with the data preprocessing techniques and least squared estimation , Taylor polynomial model was used to model geo-magnetic normal field in super-small scale space , and the relevant local geomagnetic charts were drew.The simulated results showed that Taylor polynomial model could depict the dis -tribution of geomagnetic normal field in super-small scale space .Provided a reference for geo-magnetic model in super-small scale space , and it could be reliable referent field for determi-ning the magnetic anomaly in small scale space .
