Abstract
To uncover what is “the comfortable landscape”, it is necessary to study the effect of landscape factors on the amenity of human emotion. In this study, to establish a method to evaluate amenity of landscape regarding the cognitive characteristics in our human nature, the stress-releasing effect of river landscape was analyzed by various physiological indicators.
The stress level of 29 panels was measured by systolic and diastolic blood pressure, interval of heartbeat, skin temperature and secretory immunoglobulin A concentration in saliva indicating activities of sympathetic and parasympathetic nerve, through the experiment. In experiment, a sequence of a stress elevating stroop test following a slide show of landscape view with high or low naturality was repeated three times. For the slide show, two CG sets of high and low naturality controlled in a river-terrace covered with and without green grass were designed, respectively.
It is shown that there are significant differences between slide sets with high and low naturality in alterations of four physiological parameters except beat interval. The stress-releasing effect of high naturality CG set is higher than that of low naturality set. These results show the usefulness of physiological indicators in exploration of landscape elements affecting to the amenity.
