The desert area is widely distributed in the northwest of China,dry less rain,more wind sand,big temperature differ-ence between day and night.In order to respond to the"14th Five-Year Plan"development plan and promote the green transfor-mation and upgrading development of highway construction in desert areas,based on the unique characteristics of desert highway,a green degree index system with 6 first-level indexes and 28 second-level indexes is established.The G2-entropy weigh method combination weighting method is used to reasonably determine the comprehensive weight of indicators.Combined with the mat-ter element extension concept,the greenness is divided into five levels:dark green,medium green,green,light green and non-green,and the evaluation model of desert highway greenness was constructed.The feasibility of the model is verified by using the model to evaluate the HW-3 section of S21 Altai-Urumchi Expressway phase Ⅰ project.
