It has been an important social and political problem to construct the new utilization system of paddy field.We have researched into the change of paddy field utilization system in Tohoku District after the Second World War.The reason why we choose the Tohoku district is that we can see drastic and typical change of it, for example, two crop a year, paddy-upland rotation, specialization in rice production on paddy field, reclamation of paddy field, making the upland to paddy field, and cultivation of upland crop in paddy field.And we find that it's necessary to make a intensive, diversified, and organized farming for advancing the highly usage of paddy field.

构建新的水田利用体系已成为一个重要的社会和政治问题。我们对二战后东北地区水田利用体系的变迁进行了研究。之所以选择东北地区，是因为我们可以看到东北地区发生的剧烈而典型的变化，例如一年两熟、水旱轮作、稻田专业化生产、水田开垦、旱地改水田、 我们发现，推进水田的高效利用，必须实行集约化、多元化、组织化种植。
