On the basis of sporo-pollen analysis of different Quercus liaotungensis forests in the Qinling Mountain and loess areas, the differences in the composition and quantitative distinction between two kinds of oak forests are discussed in the paper. The material shows that the charateristics of sporo pollen assembledge of Quercus liaotungensis in the Qinling Mountain are: the pollen content of trees and oak is low, the moist resistant composition among pollen grains of bush and herb is dominant, and the sporo-pollen content of vine and pteridophyte is high. The characteristic of sporo pollen of Quercus liaotungensis in loess areas are: the pollen content of trees and oak is high, the pollen of drought endurable composition among the pollen grains of bush and herb is main, and the sporo pollen content of vine and pteridophyte is small. According to characteristic composition, we can distingwish two kinds of Quercus liaotungensis forests.
