为培育祁连山水源涵养林资源，对该林区青海云杉林抚育更新进行了调查，结果表明：影响青海云杉林天然更新的主导因素是水热条件及其时空组合和配比、林分郁闭度、林内地被物厚度和盖度以及放牧。更新迹地的管护是人工造林更新的关键环节，封山育林是促进天然更新和造林更新的重要手段和措施。森林抚育有利于培育后备资源，在抚育强度为８．５％～３０％，抚育后林分郁闭度为０．５～０．６时能有效地促进天然更新。
In order to cultivate the resources of water conservation forest in Qilian Mountains, the tending and renewal of Qinghai spruce forest in this area was investigated. The results showed that the dominant factors affecting the natural regeneration of Picea crassifolia forest were the hydrothermal conditions and their space-time combination and ratio, Closure, forest cover thickness and coverage, and grazing. The management and protection of the updated sites is a key link in the reforestation of afforestation. Closing off hillsides for afforestation is an important means and measure to promote natural regeneration and reforestation. Forest tending is conducive to cultivating reserve resources, which can effectively promote natural regeneration after the tending strength is 8.5% ~ 30% and the canopy stand density is 0.5 ~ 0.6.
