chinois. 阐明景观要素对长白山地区金沟岭林场森林景观质量的影响，探究研究区森林景观的合理构建技术。以影响近景景观美学质量的13个景观要素为评价指标，采用SBE法对研究区内的30处林内景观进行评价，应用数量化理论Ⅰ建立美景度值与各景观类目之间的景观评价模型。在13个景观要素中，针阔比、树干形态、通视性、下木盖度、郁闭度是影响研究区森林景观美学质量的主要因素，其偏相关系数t检验结果均达显著或极显著水平，复相关系数检验结果达极显著水平(F=10.999)。针阔比30%、树干通直、通视性好、灌草覆盖度高、郁闭度为≥0.7～0.9的森林景观具有最高喜好度。

The research was to determine the relationship between landscape elements and near-view forest landscape quality of Jingouling forest farm of Changbai Mountain and to suggest reasonable management of the study area. Thirty in-forest landscapes were evaluated by scenic beauty estimation (SBE) method in this paper, with thirteen landscape elements affecting the near-view forest landscape Aesthetic quality as index. Multivariate linear models for estimation of landscape quality between favor degree and the structural factors of in-forest landscape were established using Quantitative TheoryⅠ. The results showed that the main elements affecting the Aesthetic quality of the study area were the Coniferous Proportion, trunk form, Visibility, undergrowth coverage and canopy density with the partial correlation coefficients significant or very significant by t-test; The multiple correlation coefficient of the model was very significant by F test (F=10.999). Preference is shown on forest landscapes with Coniferous proportion 30%, straight trunk, higher undergrowth coverage and the canopy density ≥0.7-0.9.
