Abstract: For the sake of studying the influence of the complexity of the landscape elements of grassland highway on the eye movement index of the driver, field tests were carried out, 5 participants' blink duration, fixation duration, the pupil diameter and scanning amplitude were collected on a grassland highway having three landscapes. The eye movement indices were collected by BeGaze2.4 and analyzed by SPSS. The relationship between the three landscape elements and the eye movement index was established and the variation law was analyzed. The results of the analysis were verified by a subjective questionnaire survey. The results show that the increase of landscape elements makes both the drivers' fixation duration and blink duration reduce,but makes both the pupil diameter and scanning amplitude increase slightly. Compared with the landscape a and c, landscape b can increase more grassland highway driving comfortableness, reduce the negative emotions.

Key words: grassland highway, landscape elements, driver, eye movement indices, effect rule
