中文摘要：
本文结合快速傅里叶变换算法，将观测面和延拓面测量数据的平面近似Poisson积分方程转换到频率域进行计算，提高了计算速度．为了减弱传统向下延拓基础模型的病态性并进一步提高计算结果的精度，采用迭代Tik-honOV正则化法和Landweber正则化迭代法来实现航空重力测量数据的向下延拓，取得了较好的延拓结果。
英文摘要：
Combining with the Fast Fourier Transform （FFT） algorithm, the plane approximate Poisson integral equation of the surveying data on the observation and continuation plane are transformed to the frequency domain, and the computation speed is increased. In order to weaken the instability of traditional downward continuation model and to improve the result precision, the iterative Tikhonov regularization method and Landweber regularization iteration method are employed to implement the downward continuation of airborne gravimetry data, and the continuation results with good precision are also achieved.
