摘要
利用闽北地区1988年和1993年两次森林资源连续清查487块异龄林固定样地资料,运用主分量分析和回归正交设计方法分别选出异龄林地位主导因子和建立地位质量指数模型,在此基础上,建立了包含地位质量指数因子的异龄林生长矩阵模型.
Based on the data obtained from 487 sample plots of uneven-aged forest of Continuous Forest Inventory of 1988 and 1993 in Northern Fujian province, main site factors of uneven-aged forest were first reserched by using Principle Components Analysis, and then the site quality index model was established by using the Orthogonal Regression Design method. Based on it, the growth matrix model of uneven-aged forest containing the factor of site quality index was established.
