| Research Abstract |
We noted the indicative characteristics of the plant remains and collected them to examine the environment and agriculture of the Middle Ages from a Grant-in-Aid for Scientific Research on Priority Areas (fiscal 2003-2006). Based on plant remains analysis, we examined the change of the environment and the Agriculture of the Middle Ages. Development and agriculture of the mountainous district of the Middle Ages were revealed from pollen analysis and diatom analysis at following cores of sites : Ogura-ike site (Kyoto Prefecture), Motoki-kusunokidani site (Isikawa Prefecture). In the mountainous district, secondly forest classes such as Pinus densiflora, deciduous trees (Quercus serrata, Q. acutissima) and evergreen broad-leaved trees (Quercus glauca, Castanopsis sieboldii) was distributed, and slash-and-burn agriculture of buckwheat and millets was done. In the middle ages the mountainous district was developed.
In a Grant-in-Aid for Scientific Research on Priority Areas (fiscal 2003-2006), in order to make use of restoring the paleoenvironment and agriculture of the Middle Ages, we collected dates of plant remains at areas and sites such as Kawati Plains, Nara Basin, Tokai district, Funai-machi site, Nagoya-castle site and Negoro-temple site. In the plains, the agriculture was changed at 12th century. The dry field agriculture such as of buckwheat and wheat and bean became popular and Large-sized rice grains appear. In the plain, secondly forest classes such as Pinus densiflora, deciduous trees (Quercus serrata, Q. acutissima) and evergreen broad-leaved trees (Quercus glauca, Castanopsis sieboldii) was distributed. We examined analytical basics data in the DNA analysis. In the examination for analysis of topography, we collected basics dates about the land development and trade between Japanese Islands and continent
