Study On The Expressway's Road Greening

This paper is based on Nanjing-Hangzhou Expressways,and synchronized with the road construction,using the method of combining positional demonstration with model area observation and field investigation.1 Greening on the medial dividerGreening is on the basis of this function.According to the site condition of medial divider, with the purpose of landscaping,14 planting forms were compared, then the suitable plants and configuration mode was summarized.2 Greening on both sides of the ExpresswaysUsing the method of sampling, and analyzing the technological configuration,the diversity,the similarity and the quantities attribute for plant community,some characters about expressway plant community were summarized.3 Greening on the Slope8 types of eco-protection forms were observed on position, The study shows that the order for good and bad is as follows,pine and bamboo dibbling > grass rod technology> grass planting for slope stabilization>tires for soil fixation>liana for slop protection>grass bag technology>plant strip>praying linked network.4 The maintenance management of the road greeningA set of expressway's maintenance management pattern was put forward,which was scientific,reasonable,economical,highly efficient and maneuverable,and also combined technology and management into one union,so as to gain the goal for enhancing the effect, improving the efficiency and saving the cost of maintenance.5 Benefit of greening analysisChoosing the methods of landscape comprehensive evaluation index,a landscape evaluation results shows that the landscape of Nanjing-Hangzhou Expressway achieved outstanding.
