This study is to explicate an analysis of residents' opinions and sense for the improvement of river environment in rural areas.We conducted a questionnaire on the residents using six simulation models which were made on the basis of a picture of Iu River of Yakumo Village in Shimane Prefecture by computer image processing.Fifteen bipolar adjective phrases that express the emotion of river environment such as natural or artificial feeling, good or poor harmonious feeling were determined.The mean values of evaluation of these adjective phrases related to each improvement plan of river were calculated with Semantic-Differential method on the basis of questionnaire for the residents.<BR>As a result of analysis, the following became clear.There are significant regional differences in the importance of the functions of river such as flood control, water utilization, water amenity and environmental preservation.And, two common factors, Comfortableness-factor and Activity-factor, determining emotional evaluation of river environment were chosen based on the factor-loadings of the adjective phrases which were obtained by the factor analysis method.The improvement plans of river, using not concrete or stone wall but vegetable materials such as lawn, are highly rated in each local groups of investigated rural areas.But, there are regional differences in evaluation of the improvement plan of river in case of setting up playthings easily in riverside or covering bank protection with stonewall, even if the river is improved with lawn.
