对哈溪和西营河两试验区的调查数据，应用数学方法，从理论上确定出祁连山青海云杉林采伐强度为２０％，抚育间隔期为１５年；并对密度调整作了定量分析，提出了抚育采伐的技术原则，为目前自然保护区的经营决策提供了理论依据。
Based on the survey data of Haxi and Xiyinghe two experimental areas, the paper theoretically determined that the harvesting intensity of Picea crassifolia forest in Qilian Mountains was 20% and the interval of tending interval was 15 years. The density adjustment was quantitatively analyzed, The technical principles of tending and cutting were put forward, which provided the theoretical basis for the management decision-making of nature reserves at present.
