| Outline of Final Research Achievements |
The following researches were carried out in order to evaluate the facts of flooding of the paddy fields in the beginning of the Yayoi period.
①The findings of the analysis of the X-ray CT image of the spikelet excavated from the remains in the early Yayoi Period suggested that the grain filling influenced by the flooding condition of that growing period can be estimated.②The findings of the analysis of elemental composition of the seed of rice and weed under the different various flooding conditions suggested that the Cd-As concentration ratio can be an index of a flooding condition of paddy field which they were growing.③The findings of the geostatistical analysis of the water depth influenced by the undulating surface of plow layer and the height of boundary in the paddy fields in the beginning of the Yayoi period suggested that the potential flooding condition of the paddy field in that time can be clarified.
