| Abstract: | typical closed areas in east side of Qilian Mountains were compared with the control and their previous situations from the aspects of natural regeneration,growth of young trees,height of shrubbery,covering rate.The results that were evaluated by the theory of forest evolution showed that effect of enclosure of the mountainsides for regeneration was remarkable,therefore,it is an effective measure to develop water reservoir forest in Qilian Mountains. |

| Keywords: | natural regeneration closing off growth height of young tree covering rate of shrubbery community evolution |
