The Greening Design And Plant Selection Analysis Along Hignway In Desert Of North Part Of Shan’xi Province

Since entering the new century， our country in aspects of politics， economy andculture has great changes， every area in our country has a new look， but behind in this seachange， road traffic played a key role， it is a traffic road network extending in all directionsmakes political strengthened in our country， the goal of common prosperity closer， gettinga wider range of cultural transmission. Across China’s vast， north and south， east and westspan is big， different climate terrain， has created the diversity of road transportation in ourcountry， at the same time make the traffic road construction in our country face seriousdifficulties， which built in the desert highway is an important challenge of road construction.Since most of the desert expressway is located in the inland，determines the special climatecondition，we built in the desert highway when facing difficulty is very big，is not so simpleas to build the ordinary highway. The characteristics of the climate and terrain， as well as theimprovement of desert highway greening help desert environment and the safety of thehighway and efficient transportation plays an important role， so we must arrange deserthighway greening on the extremely important position. Current our country the deserthighway greening compared with other countries in the world is still far， including thelandscape design of highway in the desert， and desert highway to choose what kind ofplants， how to effective the desert highway maintenance. For China’s desert highwaygreening design and plant selection analysis， help to improve traffic safety and the localecological environment protection， so as to realize our country various areas between thepolitical economic and cultural exchanges. So this paper mainly through the desertexpressway， the paper analyses the status quo at home and abroad it is concluded that theimportance of desert highway greening， thus what green design principles and standards， atthe same time in the process of desert highway in the maintenance of the notes that areanalyzed， thus of desert highway greening and plant selection in our country， to providetheoretical support.
