项目摘要

For the purpose of understanding of forest landscape architecture and the methodology of forest management in the warm temperate Satoyama area, a few investigations as follows were carried out.1. An approach from tree architecture analysis.2. A case study on forest landscape in Shizuoka University Forests.3. Long-term monitoring of Fauna appearing in a forest landscape.A few important results were obtained from these trials as mentioned above. First, tree architecture development in 3 evergreen coniferous tree species was analyzed and consequently the standing shoot mass par tree (F(t)) evaluated by the total extension growth increments at time t could be approximated by the following extended relative growth functions,【numerical formula】 (1)where the r values were approximately 3 regardless of growth sites. In contrast, those in broad-leaved tree species (17 species) could be approximated by simple relative growth function and in addition they indicated lower r values than evergreen conifers and approximately 2.18 in the mean value. A few additional different features (e.g., branch abscission pattern, leaf weight/shoot length ratio with age, etc.) were recognized, as well. These differences between them is closely related to the difference in tree architecture and growth strategies between them. In addition, from the result of a cost-benefit analysis in broad-leaved tree species, it was suggested that broad-leaved tall trees shows competitive and sedentary strategy.After all, Landscape structure and growth increments of the Kamiatago University Forest of Shizuoka Univ. was surveyed and then a planning model of forest landscape management was proposed from the view point of multi-traffic theory conducted by the results obtained from ecological researches as mentioned above.

为了解暖温带佐山地区森林景观设计和森林经营的方法论，开展了以下几项调查。树结构分析的一种方法。以静冈大学森林景观为例。对森林景观中出现的动物进行长期监测。如上所述，这些试验取得了一些重要结果。首先，对3个常绿针叶树种的树体结构发育进行了分析，结果表明，以时间t的总伸展生长量估算的立枝质量树(F(T))可用扩展的相对生长函数[数值公式](1)来近似，其中r值约为3，与生长地点无关。而阔叶树种(17种)的R值可用简单的相对生长函数来近似，且r值低于常绿针叶树种，平均值约为2.18。一些额外的不同特征(例如，枝条脱落模式、叶重/枝长比随年龄的变化等)也被认可了。它们之间的差异与它们在树木结构和生长策略上的不同密切相关。此外，从阔叶树种的成本效益分析结果可以看出，阔叶高大树种表现出竞争和静坐的策略。在此基础上，结合上述生态学研究成果，从多交通理论的角度提出了森林景观经营的规划模型。
