| 摘 要： | 为了提供一个较为全面和通用林内景观质量评价体系及明确体系中不同景观要素对林内景观质量影响的程度，在查阅国内外风景林一致性结论的基础上，从5个项目，22个指标和68个类目，采用AHP法构建和确定林内景观评价体系及各个层次指标权重，结果表明，各项目层对林内景观的贡献程度从高到低依次是:林内美学指标>森林健康指标>林分结构指标>地被层特征指标>林木测树指标。指标层中，对林内景观美景度贡献较大的有枯枝落叶、层次对比度、枯树倒木、水平透视距离和色彩丰富度等。利用系统对北京地区油松和侧柏林进行的评价结果表明，侧柏和油松纯林的中龄林林内景观质量均值为40.81和42.4，处于很好水平，幼龄林林内景观质量均值为37.39和40.55，处于较好水平。

| Abstract: | In order to provide a comprehensive and general evaluation system on the assessment of in-forest scenic quality (IFSQ),as well as to clearly understand the grades of influences of various scenic factors on IFSQ,analytic hiberarchy process (AHP) method was introduced to construct the system from 5 items,22 factors and 68 categories,and to determine the index weights in various levels on the basis of collecting and analyzing related data within the scenic forests.The order of all items contributed to in-forest landscape was forest aesthetics＞forest health＞stand structure＞the ground layer characteristic＞forest tree measurement.Within 22 factors,those which made relatively high contributions to IFSQ included litters,dead and fallen trees,contrast level,the perspective distance and color richness.The system was applied to Platycladus orientalis and Pinus tabulaeformis forests around Beijing,the average values of IFSQ for middle-aged forests of the two species were 40.81 and 42.40,respectively,and for young forests,the values were 37.39 and 40.55,respectively,indicating that both were in good levels. |
