通过对２４块标准地及３２株解析木的调查研究，分析了乐都地区青海云杉林木生长过程和各测树因子间的相互关系。结果表明：该地区青海云杉天然林材积一直呈上升趋势，各测树因子间存在着紧密的线性或非线性关系，为科学经营青海云杉林提供了理论依据。
Through the investigation of 24 standard plots and 32 analytical trees, the relationship between the tree growth process and each tree-determining factor was analyzed. The results showed that the natural forest volume of Qinghai spruce has been on the rise in recent years. There is a close linear or nonlinear relationship between the measured tree factors, which provides a theoretical basis for the scientific management of Picea crassifolia.
