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。
Correctly evaluating the quality of forest sites and properly dividing the types of forest sites is the basis for scientific afforestation, rational management of forests and enhancement of forest productivity. The paper is the second study on site of Pinus koraiensis plantation in Maoer mountain. Based on the division of site types of Pinus koraiensis plantation, the site quality is also evaluated. Based on quantitative multivariate analysis, a quantitative regression model was established for the seven site factors of superiority and soil type of Pinus koraiensis plantation, thickness, slope direction, slope, slope position, elevation and soil thickness of layer A. The complex correlation coefficient (0.788 3) reached a significant level. Can be used for productivity prediction of Pinus koreansis stands in Maoershan area. The prepared “hat Hill pine plantation site quality evaluation table” gives hat Hill Pinus sylvestris plantation site grade score range, to take this. Hat mountain pine plantations can be 13 site type as good, better, poor three levels.
