Abstract: The assessment and grading of a highway landscape environment is the basic work of highway route layout and landscape planning, and it is also a key link to whether the highway can be integrated into the surrounding environment. This article analyzes the connotation and value standard system of highway landscape assessment and proposes a highway landscape environment assessment method that combines a quantitative assessment and a humanistic assessment. Consequently, a highway landscape environment assessment indicator system with landscape features, environmental harmony, visual environment and environmental carrying capacity as assessment contents is constructed. Finally, using the set-pair analysis method, an evaluation model for grading the quality of the highway landscape environment is proposed. The model divides the highway landscape environment into four grades and proposes highway landscape planning and design strategies under the conditions of different grades. The theory is applied in the landscape planning of the Xi’an-Baoji highway in China. The results show that the overall assessment of the total indicator is “Grade 2”, the environmental carrying capacity of the subsystem is “weak”, and the landscape quality is “good”. This theoretical approach combines discursive cognition with quantitative analysis to achieve a systematic and refined assessment of the highway construction environment.
