摘要
本文分析了Parker—Oldenburg位场反演方法中存在的问题，提出了用位场频率域快速正演方法与遗传算法相结合的位场遗传反演方法。针对遗传算法中收敛速度慢的问题，提出了两方面的改进措施，使这种位场遗传反演方法更为完善。经理论模型验证与实际资料的处理，表明该方法是有效的。
The problems in Parker-Oldenburg potential data inversion method has been analyzed, the Genetic inversion method which combining both fast forward method in frequency domain and Genetic Algorithms has been put forward in this paper. To counter the problem that convergence is slow in Genetic Algorithms, two improved measures were adopted, which made this Genetic inversion more perfection. After computing on theoretical models and using real data, the effection of this potential Genetic inversion method was verified.Ketwords: Fast forward method in frequency domain; Genetic Algorithms; potential Genetic inversion method; moho interface.
