Typical profiles in different soil orders in Beijing area were selected to be used for studying micromorphological characteristics, such as soil microstructure, skeleton grain, Pedological characteristics and pores through soil section observation and pictures analyzation in ENVI. Results showed that the differences of micromorphological characteristics among different soil profiles in Beijing were apparent. Alfisol developed fully,illuviation argillan were common in Bt horizon; Microstructure of Cambisol and Entisol were not developed well, noilluviation argillan was found, but B horizon was formed,hole structures appeared, and calcic evidence also could be found in Cambisol, indicating it developed better than Entisol. Anthropic soil showed a large number of traces of human activities, and more visible invaders, animal and plant remains, showing it more mature than the other three soil orders.
