Abstract
In this paper, the evaluation structure of river environment is investigated based on the questionnaire survey which was carried out by the committee of Seki river basin. The results are as follows: (1) Regardless of regional differences, people judge they can come into contact with river through the open space of river, and based on the judgment, they feel familiarity to the river and evaluate the river desirable. (2) There are many regional differences between the hierarchies which are influenced by the physical environment. On the other hand, there are few regional differences between the hierarchies which are influenced by people's subjectivity.
