Study On Vegetation Of Highway Greening In Shandong Province

Under the background of the highway leaping development and increasingly influence on ecological environment and landscape, highway afforestation has so many functions, such as greening environment, roadbed protection,raising vegetation coverage and reducing soil, that it can improve the coordinate development of highway and environment. So, a thorough investigation and study of present situation about shandong province highway has a guiding significance for it's development.Firstly, determined by the main vegetation types and their distribution we can know the partition of highway afforestation plant resources,and study every region in detail.In this article it needs determine all the highways in every region and analyze the greening situation of the typical highways, detailed in transmission line greening and environment afforestation. Meanwhile, it make more specific study on the plants applied on expresstway medial divider, slopes,both sides, interlinked flyover and service area,and then objective evaluation about growth characteristics,advantages and disadvantages and greening effect.Secondly, through collecting the existing research results about relevant fields and catching a few more mature, representative research,we can find some great potential species promoting shandong province highway afforestation, including local wild plants in shandong province, the existing plants but not application in highway, and topical application plants in highway having further application values to rich plant variety in highway afforestation.Based on the shandong province highway, this article researches creative on the plant of highway afforestation from the view of content.It has very obvious difference to others article about expressway greening in shandong province,which take only one highway or topical greening such as sloping and medial divider as the research objects. However,this article contains all the aspects about shandong province highway,so it is very comprehensive and systematic.By the creative research method, vegetation analysis in this article is made before confirming their growplace because site conditions determine the vegetation distribution.so,for the vegetation of highway greening,it needs firstly to know nature environment of shandong province,vegetation distribution and forestry division of shandong province,and then divide research object to three regions and even refinement study.Therefore, the defined range of research object has a definite guide characteristic about further study.
