摘　　要：根据哈尔滨 -尚志连续电磁剖面测深结果 ,研究了松辽盆地东缘盆山结合部的地质结构特征 ,尤其是对深层的地质结构取得了重要的认识。盆山结合部划分出 3个基本单元 :松辽盆地、滨东隆起区和张广才岭隆起区。盆地一侧的盖层具有双重结构。盆地具双重基底 ,即浅变质岩的褶皱基底与侵入岩的结晶基底。莫霍面在盆地一侧隆起 ,向张广才岭变深 ,隆起幅度 4km。断裂主要为岩石圈与壳断裂 ,对构造单元起控制作用。Based on the exploration results of MT array profiling in the Haerbin-Shangzhi area,we have studied the geological structure of eastern edge of combination of basin and mountain in the Songliao basin,and got important knowledge of the geological structure in deep layer. The combination of basin and mountain contain 3 basic blocks like Songliao basin,Bindong bulge region and Zhangguangchailing protuberant. The cover layer on one side of basin has double structure. Basin has double base like folding base of weak metamorphic rocks and crystal base of intruding rocks. Moho surface bulged at one side of the basin,went deeply to Zhangguangchailing with 4.1 km bulged range. Fractures are mainly lithosphere faults and crust faults,which controlled the structural blocks.
