项目摘要

On this study, An examination was done through the classified experiment which the woods photograph which was in middle distance if a person distinguishes a woods landscape by what kind of physical character was used for, and the interview investigation related to that classified reason. It became clear that "the shape of the tree crown" "tree kind" "pattern" "color" "brightness" were an important factor for the distinction of the difference in the woods landscape as that result. Then, According to the classified experiment, the resemblance occasion line of the woods landscape photograph was made in the place, and the resemblance of the woods landscape mutuality was looked for as a layered structure by a cluster analysis, and the characteristics of the common woods landscape in each cluster were extracted as a word. Then, the examination which the general idea of Fractal Dimension was used for about fixed quantity-ization of the index from the point of Texture was done on the shape of the tree crown. "Yoshino forestry area(Nara Prefecture)", "Hita forestry area(Ooita Prefecture)" was taken up, and both comparison, analyses were done about the landscape of the surface of artificial woods of a Japanese cedar. As a result, it became clear that though Yoshino faced detailed soft Texture was shown, Hita faced hard Texture which a pattern was gathered orderly was shown.

在本研究中，通过分类实验检验了一个人用什么样的物理特征来区分森林景观的中距离的森林照片，以及与该分类原因相关的访谈调查。由此可见，“树冠形状”、“树种”、“图案”、“颜色”、“亮度”是区分森林景观差异的重要因素。然后，根据分类实验，在该地点绘制森林景观照片的相似场合线，通过聚类分析寻找森林景观相互相似性的分层结构，并将每一聚类中常见森林景观的特征提取为一个词。然后，利用分形维数的一般思想，从纹理的角度对树冠形状进行了指标定量化的检验。以“吉野林区（奈良县）”、“日田林区（Ooita县）”为研究对象，对杉木人工林地表面景观进行了对比分析。由此可以看出，吉野面对的是细致的软纹理，而Hita面对的是有序聚集的硬纹理。
