摘要
通过对祁连山东端１７块具有代表性的封育地与封育前及对照区的天然更新、幼树高生长、灌木高度、盖度进行对比分析，得出了封山育林效果显著的结论，并运用森林群落演替理论对试验结果进行了论证，从而说明封山育林是发展祁连山水源涵养林的一项重要而有效的措施。
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.
