英文摘要：

This paper presents the optimization stratification technique for magnetotelluric sounding data interpretation,and shows a case history in Lengshui area. We invent the opti- mization stratification technique for magnetotelluric sounding data interpretation based on principle of layering technology to electrical logging curve to solve the difficulty. We check the feasibility and the validity of this technology both in experimentation and practice. It is very useful to use this method for detecting geologic configuration characteristics and finding new good exploring objects.
