摘要
柞树林是我国东北林区重要的树种之一,具有重要的经济价值和生态价值,但至今关于柞树林的研究较少。本文根据汪清林业局金昌林场的标准地的数据资料,对柞树林林分的树高与株数的关系、树高与胸径的关系进行了探讨和分析;并利用多模型选优,得出了两个较优的树高曲线模型。
Quercus mongolica is one of important species in northeastern China, it has important economic and ecological value. However, the research on Quercus rnongolica are rare. On the basis of detailed data collected in Jincang Forestry Farm of Wangqing Forestry Bureau, this paper discussed and analyzed the relationship between of tree height and numbers and tree height and diameter. Two optimal were obtained to represent tree heigh curve by multi-models selection,
