This paper aims to introduce the authors' study on the impact assessment of highway construction on landscape through quantitative analysis based on characteristic analysis and assortment of affecting factors in such construction projects. The results of our study reveal that: (1) our method can meet the assessment requirement for its analysis of the three indices of landscape function and stability, landscape interference and landscape quality. Such quantitative analyses can produce a good effect on the impact assessment; (2) the project has impact on the degree of landscape collision, but the impact is very strong; (3) the function and stability of landscape in assessment areas would be weakening; (4) the project may have effect on the landscape quality in barren alluvium hill areas but fluvial terra region would suffer some kind of middle impact while the other kinds of areas may be brought about slight impacts; (5) selecting plant fitting the field, enhancing the ratio of the evergreen plants and landscape plants are the main methods to renew the degraded landscape.
