摘要
正确地评价森林立地质量和恰当地划分森林立地类型是科学造林、合理经营森林、提高森林生产力的基础。文章为帽儿山红松人工林立地研究之二,在划分了红松人工林立地类型的基础上,又对其立地质量进行了评价。采用数量化多元分析方法,建立了红松人工林优势高与土壤类型、A层厚度、坡向、坡度、坡位、海拔、土壤厚度7项立地因子的数量化回归模型。其复相关系数(0.788 3)达极显著程度。可用于帽儿山地区红松人工林立地生产力预测。所编制的“帽儿山红松人工林立地质量评价表”给出了帽儿山红松人工林立地等级的得分区间,藉此。可将帽儿山红松人工林13个立地类型评为好、较好、差三个等级。
The paper is the second part of the study on sites of korean pine(Pinus koraiensis) plantation on Maoershan Mountain. Based on the relation of site factors to dominant tree height, a multiple regression model was developed by using the numberial model Ⅰ for site quality prediction of Korean pine plantation. A table of site quality evaluation was made on the base of the tables of site type and site factor score of korean pine plantation. It is convenient and simple to evaluate site quality by using the table.
