| Road greening is an important part of the urban green space system and a transportation hub connecting various cities.In addition to daily transportation,it also has the function of beautifying the environment and improving air quality.Road greening can give full play to its traffic function and ecological benefits.Not only a reasonable planning layout and effective plant configuration are required,but scientific and reasonable maintenance management is also essential.Therefore,it has certain practical significance for its later maintenance management evaluation research.In this paper,through on-site investigation and selection of analytic hierarchy process,a road greening maintenance management evaluation system is established.The research results are as follows:(1)There are 46 kinds of road greening plants used in the South High-tech Zone,of which the types of evergreen trees and deciduous trees are equal,both of which are 8 types;there are 14 types of evergreen shrubs and only 1 type of deciduous shrubs;12 types of herbs and 3 woody vines species,basically achieved the organic combination of shrubs,shrubs and vines.(2)Road greening has problems such as poor plant growth,irregular pruning,diseases and insect pests,weeds and weeds,debris garbage,man-made damage,and bare soil.(3)Select 14 indicators that affect the road greening management,including plant health,road environment ornamental,road environment,and maintenance management,to evaluate road greening management.The evaluation system has good reliability and effectiveness.The degree can be used in the assessment of road greening maintenance management in the area.(4)According to the results of field investigation and evaluation,the maintenance management experience of the well-maintained road sections is analyzed.(5)Through investigation,the following problems existed in the road greening construction and maintenance of the high-tech southern area: the three links of planning,construction and maintenance were severely disconnected;there was a phenomenon of reconstruction and light maintenance;there were few maintenance personnel,large workload,and low professional quality;the maintenance method was backward;maintenance management work is not in place;lack of laws and regulations related to greening.(6)Suggestions are made for problems in road greening construction and maintenance management. |
