| 内容記述 | The purpose of the present note is to show how natural forests have been destr-ucted by road construction in natural parks. In the first reports the author discussed the methodology to analyse these problems. In this paper he tries to consider the influence of roads among various kinds of vegeta-tion. As the stand of the study, three national parks were selected : Kirishima-Yaku National Park, Unzen-Amakusa National Park and Aso National Park in Kyushu District. In these national parks had been constructed many park roads almost on volcanoes : Volcano Sakurajima, Volcano Kirishima, Volcano Unzen and Volcano Aso. By making a survey of the human impacts on natural forest in these regions, it is possible to make clear the influence on various developmental stages of the vegetation on the lava flow. The author studied the floristic composition and made a comparative study in different stages of succession. This work was carried out from August to November 1971. And almost all the roads investigated had been constructed over 10 years before. So the time passed sufficiently enough for the occurrence of effect by the construction. The results are as follows. 1. The difference of vegetational change clue to the difference of successional stages. When a road was constructed within the vegetation of early stages of primary succession, the pioneer plants appear along the roadside frequently. Because the soil is stabilized and enriched by human influence more in the stand of roadside than far from the road. But in the later stages of succession, the characteristic species appear along the roadside, which indicate retrogression caused by the strong influence of human impacts. 2. The difference of vegetational change because of the difference of climatic climax. There are two climatic climax in Kyushu District : evegreen broad-leaved forest and summergreen broad-leaved forest. The effect of road construction is less in the former than the latter. 3. The vegetational change in substitution communities. Substitution communities exist under the human influences, such as clear cutting, afforestation and so on. The effect of road construction is less in substitution communi-ties than in natural communities. The author supposes, it may by reduced to that the road construction can not influence more strongly than the usual human influence of forestry. | |||||||
