Abstract: The mongolian oak (quercus mongolica) population maintains its stability and development through sexual (seed production)/asexual (sprouting) regeneration. The natural regeneration process was revealed by field investigations and experiments. The main environmental factors that influence the sexual and asexual regeneration were discussed by means of multivariate analysis,which exhibited the selective principles of environmental sieve to the established seedlings in different developmental periods.

Key words: increased precipitation, soil water, δD, Nitraria tangutorum.
