摘　　要：对 14条近 40 0 0km的大地电磁测深资料进行了一维及二维连续介质反演 .根据反演结果及地面地质资料解释确定了侏罗系、上三叠统底界面海拔高度图以及前泥盆系顶界面海拔高度图 。dimensional and 2-dimensional continuous media inversions of the magnetotelluric sounding data have been conducted for the 14 observed profiles with a length of about 4 000 kilometers. The elevation contour maps of the Jurassic and Upper Triassic bottom interfaces and Lower Devonian top interface, have been obtained based on the inversion results and geological interpretation. Furthermore, the tectonic unit division and oil & gas bearing perspective evaluation of Qiangtang Basin are also made in accordance with the related studies and geological materials.
