摘　　要：以对影响岷江上游景观美景度的15个景观要素为评价指标,采用SBE法对研究区30个景观进行了评价,应用数量化理论I建立了美景度与各景观类目之间的评价模型。结果表明,针阔比、郁闭度、草本盖度、平均胸径和灌木均高是研究区美景度的主要影响因素,复相关系数F=2.657（p〈0.05）。郁闭度0.5~0.69,针阔比0.3~0.49,较好的草本覆盖美景度最高,更好的透视性和较大的树木直径也有利于提高美景度,反映了当地风景林现状,也为今后的风景林研究和经营提供了新的思路和方法。Thirty landscapes were evaluated by scenic beauty estimation（SBE） method in this paper,and 15 landscape elements affecting the landscape aesthetic quality were used as indexes. Multivariate linear models were established for the estimation of landscape quality between favor degree and the structural factors by using Quantitative Theory I. The results showed that the main elements affecting the aesthetic quality of the study area were the ratio of the needle and the width, the density of the depression, herb coverage, average diameter at breast height and the height of the shrubs. The multiple correlation coefficient F was 2. 657 （p 〈 0. 05 ）. Preference was shown on forest landscapes with canopy density 0. 5 0. 69, coniferous proportion 0. 3 - 0. 49 and better herbaceous cover. More perspective and larger tree di- ameter might also improve the beauty which not only reflected the current situation of the local scenic forest, but also provided a new idea and method for future landscape forest research and management.
