Abstract This paper selects tele-seismic records from 58 permanentstations setting in Jiangxi and Fujian provinces,from January 2011 and December 2012.We get information on crustal thickness and average Vp/Vs ratio estimation by the H-κ stacking method. We further obtain the image of the crustal thickness and Poisson’s ratio and their variation trend by interpolation. The study shows that: crustal thickness of the study area ranges 28-34 km,characterized by gradual thinning from inland to coast in the region of SE China margin;the southern area of Jiangxi province and the coastline of Fujian province have the thinnest crust in the study area,while the eastern area of Jiangxi province and the northwesternarea of Fujian province have thicker crust.The crustal average Poisson’s ratio ranges from 0.21-0.28,increasing from land to sea; the northern area of Jiangxi province has a low Poisson’s ratio,less than 0.23, with a Vp/Vs ratio ofless than 1.70.The coastline of Fujian province has a higher ratio,up to 0.28, with a Vp/Vs ratio of about 1.83.
