摘要
立地质量评价有利于林地的生产经营。以广西斯道拉恩索林业有限公司广西南部桉树林森林资源资产评估调查数据为研究对象,通过方差分析小班平均树高与海拔等立地因子的相关性,以对林分平均高有显著性影响的因子为因变量,小班平均高为自变量建立模型。通过模型求解理论小班平均高以评价林地的立地质量,立地质量为一般的地块占8.83%,立地质量为良的地块占57.65%,立地质量为优的地块占33.51%。
Evaluation of site quality was beneficial to forestry production and management. Taking the survey data of Eucalyptus forest resources assets appraisal in southern Guangxi from Guangxi Stora Enso forestry limited company as the research object,the correlation between average height of sub-compartment and site factors was analyzed by ANOVA and the model was established by using the factor with significant effect on stand average height as the independent variable,and average height of sub-compartment as dependent variable. Theoretically,the average height of sub-compartment could be worked out by this model to evaluate the site quality of forest. The general site quality accounted for 8.83%. The good site quality accounted for 57.65%,the excellent site quality accounted for 33.51%.
