Based on the restoration ecology thesis, the different greening types of expressways are put forward that combined with the guidance of expressway greening choice and the investigation for expressway greening in Gansu province. Analyzing the functions, effects, basic demand, principles, protection techniques of greening in different areas on expressway (slope, central median, interchange area, service area, and toll station) and the natural environment in Gansu province, the vegetation choice in the south, the middle, the east and the west of Gansu province are put forward. The expressway greening type in loess area is studied by analyzing the interchange trial greening area that G312 (from Chankou to Liugouhe). The problems of expressway greening in Gansu province are also studied, and some solved methods are put forward. In the high attention to the ecological environmental protection and improving traffic safety today. The research in this paper is contributed to high-level highway ecological greening in acrid and semi-acrid. Keyword：High grade highway Green; Traffi
