对祁连山东端8块具有代表性的封育区与周围未封育对照区的森林凋落物、苔藓枯枝落叶层及其容水量、土壤含水率进行了对比分析，结果表明，封山育林可以显著提高水源涵养效能。可作为培育祁连山水源涵养林的一种有效途径。
Forest litter, moss litter layer, water holding capacity and soil water content of eight representative closed areas and the surrounding non-enclosed control area in the eastern Qilian Mountains were compared and analyzed. The results showed that the closing hillsides could be significantly increased Water conservation efficiency. It can be used as an effective way to cultivate water conservation forests in Qilian Mountains.
