Vertical viewing angles of wind power generators are often applied to estimate negative psychological impacts with factors of “degree of concern” and “feeling of oppression” for the environmental impact assessment of landscape. Here we introduce new factors “degree of attractiveness” and “degree of preference” to judge whether the landscape of wind power generators gives positive or acceptable psychological effect or not. Showing landscape photos of wind power plants to subjects, data of impression were obtained by means of questionnaires with those four factors. As results, when the maximum vertical viewing angle was less than 3 degrees, the landscape tended to be preferably accepted. Also, when vertical viewing angles were 5 degrees or more, those psychological effects did not lean solely towards negative, as positive psychological effects were also observed.
