 note = {application/pdf, 長野県北部にある善光寺平には条里型地割が認められる地点がいくつかある。そのひとつ更埴条里遺跡において初めて埋没条里型水田が確認されたが，その後，石川条里遺跡や川田条里遺跡でも同時期の埋没条里型水田跡や古代の水田跡の存在が明らかにされた。何れも千曲川沿岸の後背低地に立地する遺跡であるが，近年，これらの遺跡が高速道路・新幹線建設に伴って大規模に発掘調査されたことから新たな知見がもたらされた。本稿ではこれらの発掘調査成果を中心に善光寺平南部の古代水田の様相を紹介するものである。
近年の調査成果で注目される点は，９世紀末の洪水砂で埋没した条里型水田跡が広範囲で調査されたこと，広域での半折区画の採用が知られたこと，さらに先行する古代水田跡が一部で確認されたことがある。また，９世紀末の埋没条里型水田が（８世紀末前後から）９世紀前半ころに成立したと推測されるものの，異区画水田が微妙な時期に存在した可能性が知られるようになり，条里型水田の出現が単一か，段階的なものか微妙な問題を生じている。この問題は所見に不確定なところがあって明確な問題として提起しにくいところもあるが，併せて触れる。, There are several locations in the Zenkoji Plain in northern Nagano where Jori system-style land divisions have been found. The first embedded Jori-style rice paddies have been confirmed at one of these sites, the Kōshoku Jori Sites. However, it later became clear that artifacts of embedded Jori-style rice paddies of the same period and the remains of ancient rice paddies were also found at the Ishikawa Jori Sites and Kawata Jori Sites. All of these are sites in the lowlands behind the banks of the Chikuma River. In recent years new discoveries about these sites have been made as these areas were excavated and surveyed on a large-scale as a result of expressway and bullet train construction projects. In this paper the author introduces the aspects of ancient rice paddies in the southern Zenkoji Plain, focussing on results from these excavation surveys.
The following issues are some of those that have been the focus of survey results of recent years. Jori system rice paddy sites that were buried in sand from flooding in the late ninth century were studied extensively. The use of half-size divisions in a wide area becomes known. A group of even older ancient rice paddy sites was also confirmed. It is also surmised that the embedded Jori system rice paddies from the late ninth century were established from the end of the eighth century to the first half of the ninth century and it has become known that there is a possibility that rice paddies that were not part of the division system also existed in an undefined period. This has produced the slight problem of whether the appearance of the Jori system rice paddies occurred in a single step or in stages. The answer to this is inconclusive and it is difficult to raise it as a clear issue, but the author attempts to touch on the subject.},
