Hilis and coastal lowlands alternate in the coastal area of Fukushima Prefecture. The coastal lowlands are uplifted drowned valleys. The author investigated Soma area in the northern part of this coastal area, and is especially concerned with the Jomon transgression, and the landforms consisting of fluival deposits and surface material. The sea seems to have reached up to the 5m contour line during early Jomon time and bays were formed. The speed of aggradation depends on the scale of rivers which flowed down the coastal lowland.
There are some differences in the development of landforms and surface materials at each coastal lowland. On the coastal lowlands with small rivers, fluvial deposits are hardly found and mucky soils are widely distributed. On the other hand, on the coastal lowlands with large rivers, floodplains and natural levees develop well. But, there are some differences between Nakamura area and Haramachi area, in spite of the same scale of rivers flowing. In the Haramachi area, sandy and gravelly soil develops more than Nakamura area, and its river carries gravel to the coast. By the way, coast in the Haramachi area is rapidly retreated and it is said that since terrace building southern area of this coast is uplifted compared with the northern area. These bring the differences.
In conclusion, the author considers that shoreline process, scale of river and tectonic movement are important factors for the development of coastal lowlands.

おもに前期古墳から出土する底部穿孔壺は,何を目的に古墳上におかれ,どのような祭祀が行われたのか。小論は底部穿孔壺を用いた古墳祭祀を俎上にあげ,その意味の解釈を試みる。
まず底部穿孔壷祭式の変遷をあとづけ,その原形が底部の打ち欠かれた少数の装飾壺が古墳上におかれるというものであることを明らかにする。次に,東アジアの稲作地帯に分布する農耕儀礼のあり方に着目し,種籾を貯蔵する壺に穀霊が宿るという信仰がさまざまな形で広く分布していることを確認する。そしてこれと同様の思想が弥生時代以降の日本列島にも存在していた可能性を考え,壺が穀霊信仰にもとづく農耕儀礼と密接な関係にある遺物であることを推測する。壺が用いられた葬送祭祀は,これを破砕もしくは穿孔することで壺に宿ると観念された穀霊を後継者へ継承することを目的とし,その被葬者は農耕司祭者としての性格をもっていたのではないかということを指摘する。

The purpose for this study is to understand the evaluation structure in a region. For this object, we made investigations for residents and experts about evaluations of regional resources in Haramachi-city. The results are as follows ; 1) Infrastructures were valued in the high, private places and sightseeing facilities were in the low, and nature and culture were in the middle. 2) The evaluation between residents and urban planners was more different than ecologists. 3) The resident's evaluation has influenced by their residential places and jobs.
