Elementary Discussion The Plant Selection And Configuration Of Road Greening In Anshan City

In recent years,the development and landscape construction of Anshan had achieved positive results.Landseape of city streets was upgraded ignificantly.Trees,shrubs,and other plant materials are the basis of landscape,and it is important to study the selection of plants in street landscape.In this paper,the research,which is based on the AHP analysis method,want to establish a plant evaluation system for streets landscape in Anshan.Another,tis paper want to research the design method about streets landscape.The city of Anshan,which is saided in the central of Liaoning Province,is according to Qianshan Mountains on east and aroading Liaohe plain by weast.The city have natural vegetation landscape.The concretion of city is "one ring,two areas,four axis,eight mountain".This research involved 78 piants plots,about 11 trunk roads,15 roads,15 branch road.Sample is h 60m lengt and width along roads red line.Sample involving tree,which about 17 species,13 families,15 genera;shrubs,which about 10 species,7 families,9 genera;greening,which about 10 species,8 families,10 genera.Vertical structure of plant community is about 8 forms,that is,trees,shrubs+grass,small trees+grass,trees+shrubs,small trees+shrubs+herbs,trees+shrubs+herbs,trees+shrubs,trees+shrubs+shrubs+herbs.The structure of species,this is,the tree is evergreen,and the mixed forest is less;the shrub is evergreen,and the landscape is simple.This paper research the advantages of each quadrat,diversity.According to the AHP method,the evaluation system of street landscape in Anshan is constructed.The evaluation system is composed of five criteria,such as viewing characteristic,ecological benefit,growth trend,anti-performance,cultural spirit and so on.Ornamental characteristics including color,ornamental period,smell fragrant,plant morphology,peculiar nature,ornamental obvious index;ecological benefits including fixing carbon and releasing oxygen,smoke and dust removal,cooling dehumidifying index;growth including height,crown width/unit number of trees,growth speed and transplanting efficiency index;anti inverse properties include salt,cold,drought tolerance,water wet index.According to the evaluation system,selection about Ⅰ degree plants 15 species,including 5 species of tree,5 species of shrubs,5 species of greening,Ⅱ degree plants 23 species,including 13 species of,5 species of trees,5 species of shrubs,5 species of greening.These plants can be as the main plant of Anshan City urban road greening.The configuration principle of plant group is the ecology,experience and beauty.This paper analyzes the mode of plant configuration in streets.The roadside plants with dense woodland,shrubs,interface ribbon configuration mode.
