在华山松天然分布区的巴山(西段)林区华山松人工林中设置5种密度级共66块标准地进行定位观测,对收集的16~21年间该林分的各种生长量指标进行分析检验。由此得到各密度级的各种生长量平均指标,可供华山松林分合理经营和规划设计参考。
In the natural distribution area of Pinus armandii (Pinus armandii), 66 species of five densities were set in Pinus armandii plantation in the natural forest of Bashan (western section) in the natural distribution area of Pinus armandii. The data of various growth indexes of the stands were collected from 16 to 21 years Analysis test. The average growth index of each density level is obtained, which can be used for rational management and planning and design reference of Pinus armandii.
