Abstract: On the basis of the theory of plate tectonics, according to the organic relationship between the successful model of basi:xai dynamic types and the geological conditions,main gas-bearing basins in China are classified into six groups and nine sub-groups comprising fifteen kinds by which the gas-bearing geological factors of all kinds of basins are studied, which show that in the east of China marginal sea have advantage geological conditions becoming middle or even big gas fields and intracontinental rift basins may find many small and middle gas fields some of which are possibly combined with each other so that they can form middle or big gas fields,that the important zones of middle or big gas fields in the west of China are craton transformed basins.
