摘　　要：利用瞬变电磁法(TEM)研究永久冻土层的分布规律,为中国东北天然气水合物远景调查的进一步研究提供依据。采用拟地震成像法反演瞬变电磁法野外数据,有效地划分出反射界面和电性层位,成功地推断出漠河地区永久冻土层的分布。反演结果表明,漠河SN(2)测线永久冻土发育良好,厚度较大,且具有一定的连续性,与直流电测深法揭示的结果相一致。TEM method is used to study the space distribution regularity of permafrost strata in order to offer the base for further research of the northeast natural gas hydrate prospective investigation. This method gets better geological result by using pseudo-seismic interpretation imaging technology to inverse TEM field data to divide the reflect interface and electric level and then inferred the distribution of permafrost strata of Mohe region successfully. The inverse result shows that the permafrost strata of the south-north second measurement line developed well with large thickness, had certain continuity, and was consistent with the result of VES.
