Abstract：Receiver functions are calculated by using teleseismic records of Shanxi Digital Seismic Network and crustal thickness and Poisson's Ratio in Shanxi area are obtained by stacking receiver functions with H-Kappa technique. The result show s that crustal thickness in Shanxi province exists obvious difference. The average crustal thickness in Shanxi is about 39 km.The difference of crustal thickness between south part and north part has a higher value.The crust beneath ANZ(Anze) station is the thinnest (36 km), biggest thickness(43 km) appears beneath SHZ station.Poisson ratio in Shanxi Province is about 0.24-0.31,which is consistent with the Poisson's ratio of the world.The crustal thickness of Shanxi area is pos-itively correlated to the topography.Meanwhile,the crustal thickness of Shanxi area is negatively correla-ted to Poisson's ratio.
