项目摘要

In this study, we examined the variation of vertical vegetation zone on Mount Fuji using the aero- photographical, vegetational, Climatological, and bibliographic methods. Analying 11 aero-photographs, we could get some evidences of disturbance on vegetation. Especially, the effects of avalanches were clearly impressed on it.On the northwestern slope of Mount Fuji, a conspicuous stepped microrelief which might influence the vegetational distribution pattern is developed. Analysing the process of this step formation seems to be deeply concerned with making clear the variation of vertical vegetation zone. In order to clarify the process of step formation, we have set two paint-lines on the slep at 2800 meter asl. About a year after, we checked the movement of gravels along the paint-lines. They did nove a little only on a step terrace but on a cliff. According to the meteorological data at the study site, a freezing or thawing period which should control the peri-glacial phenomenon is very short. A further detailed analysing the aero-photographs showed us the existence of stepped microrelief in the forested area. These facts might suggest that the microrelief had made during the colder period, accordingly, the vegetation on northwestern slope of Mount Fuji is just progressing in primary successional phase founding on the microrelief.Regrettably, among the historical documents, we cannot get yet the significant infofrmation on the vegetation of Mount Fuji. It is one of the further subjects of this study.

在这项研究中，我们用航空摄影、植被、气候学和参考文献的方法研究了富士山垂直植被带的变化。通过对11张航片的分析，我们可以得到一些干扰植被的证据。在富士山西北坡，发育了明显的阶梯状微起伏，可能影响植被分布格局。分析这一阶梯的形成过程似乎与弄清垂直植被带的变化密切相关。为了弄清台阶的形成过程，我们在海拔2800米的雪橇上设置了两条油漆线。大约一年后，我们检查了沿着油漆线的碎石移动情况。他们只是在台阶上，而不是在悬崖上稍作停留。根据研究地点的气象资料，控制冰周现象的冻融期很短。对航空照片的进一步详细分析表明，森林地区存在阶梯状微起伏。这些事实可能表明，富士山西北坡的植被是在较冷的时期形成的，因此，富士山西北坡的植被正处于以微浮雕为基础的初级演替阶段。遗憾的是，在历史文献中，我们还没有得到关于富士山植被的重要信息。这是本研究进一步探讨的课题之一。
