We collect waveforms of worldwide teleseismic events by 23 broadband seismic stations from the Inner Mongolia Autonomous Region Digital Seismic Network during period of 2009-2016. Using the receiver functions of the H-k method,we calculated the Moho depth and Poisson's ratio beneath those stations constructed on bedrocks. We present the Moho depth and Poisson's ratio distribution characteristic of Greater Khingan Range orogenic belt and surrounding regions based on a compilation of 277 seismic observation array and mobile seismic array for receiver functions H-k analysis published in the literature and our results. Comprehensively analyzing the fine crustal constrains distribution information in this study leads to the following conclusions. The Moho depth of the study area gradually increases from east to west overall,varies from 25.0km to 42.3km and the mean of 33.5km,with the shallowest and deepest Moho being located in the Songliao Basin(27.0-35.0km) and the western of the Greater Khingan Range gravity anomaly gradient belt(41.0-42.3km),respectively. The average Poisson's ratio is about 0.27 and varies from 0.19 to 0.33 for the study area. It is higher than the average Poisson's ratio of global continental crust. The highest Poisson's ratio is found in the volcanic region and basin with the thick sediment layer. The Moho depth correlate well with the surface topography and the Airy's isostasy model is suitable for this area. The existence of significant anticorrelation between Moho depth and Poisson's ratio in the Greater Khingan Range area. However,no clear correlation is observed in the Songliao Basin and its adjacent area. It may reflect that the area experienced quite complex processes of crustal modification in the tectonic evolution process of the Songliao Basin.
