説明
In recent years, people have become aware of various functions and significance of Secondary forests, which is called Satoyama. However, Satoyama is decreasing in both quantity and quality. Therefore, a preservation plan is needed for Satoyama. The purpose of this study is to ana-lyze changes in Satoyama vegetation using the Rapid Survey Map, that is, a map produced by the Japanese army in the 1880s, a vegetation map in the 1970s, and GIS data in the 1990s. The results are as follows. The forest vegetation in the 1880s was dominated by Quercetum acutissimo-serratae. The rest was mostly Pinus densiflora forest. Between the 1880s and the 1970s, forest areas decreased, and succession from a Pinus densiflora forest to a Quercetum acutissimo-serratae forest occurred because of a decrease in frequency of forest use and mass-dieback of the Pinus densiflora forest. Between the 1970s and the 1990s, forest areas also decreased, and succession from a plantation to a Quercetum acutissimo-serratae forest occurred because of the change in the afforestation program.
