The aesthetic value of natural scenic spots directly decides whether the success of the tourism development or not. In order to investigate the aesthetics value of grassland landscape in Kanas scenic area,the scenic beauty evaluation system of psycho-physics was selected to quantitatively evaluate the scenic beauty of four zone grassland plots in Kanas scenic area. The plant diversity and community features of the grassland were investigated and analyzed based on the α diversity index and the structural composition of functional group,and then the effects on the scenic beauty of grassland landscape were discussed. The results showed that the aesthetics value of grassland landscape in Kanas scenic area was totally high. The scenic beauty with middleα diversity index scoredthe highest,while the scenic beauty with low α diversity index was the lowest. With the increased important value of annuals and biennials in the grassland,the important value of perennial forbs decreased and scenic beauty tended to decrease. The scenic beauty had a significant positive correlation with average height,average coverage,biomass,Shannon-Wiener index,Margalef diversity index and perennial forbs. But the scenic beauty had a significant negative correlation with annuals and biennials. It concluded that the plant diversity of grassland was the important carrier for the aesthetics value of grassland landscape. The tourism disturbance changed the plant diversity of grassland community and then deeply influenced aesthetics value of grassland landscape.
