A Study On Greening Maintenance Management Of Main Expressway In Jiangsu

This paper is depending on the study of "Greening maintenance management of Jiangsuexpressway".By surveying on the present greening situations,this study choosed Jing Hu,Lian Xuand Yan hai expressway for example.This paper is studying about the site conditions, plantspecies,greening forms and the growth situation of plants by field investigation,the maintenancepanel and data.On the basis of these,I summaryed the greening problems and explored about thegreening maintenance management of Jiangsu expressway.By combining with the questions ofgreening,taking Jing Hu and Lian Xu expressway for example,I put forward the correspondingimprovement suggestions.Firstly,I studyed about the present situation and problems of greeningon median separator.Secondly,I studyed about the situation and problems of greening on bothsides of the road and slope. Thirdly,I studied about the present situation and problems of greeningon communication area.Fourthly,I studyed about the present situation and problems of greeningon the service area and toll stations.Fifthly,I studyed about greening maintenance managementand suggestions for the improvement of Jiangsu expressway.Main results are:Firstly,I have summaryed about the plant species and greening forms of themedian separator,both sides of the road and slope,the communication area,the service area andtoll stations of Jiangsu expressway.Secondly,greening problems include difficult watering,weedsinfest,low rate of seedling planting,plant diseases and insect pests threat,not timely trimming,safe hidden troubles,not appropriate plant selection and so on.Thirdly,I summaryed abouttechnical solutions of maintenance management,and have achieved the preliminary results aboutwatering,soil management,trimming,prevention and the control of plant diseases and insectpests,replanting,fire prevention,weed control and so on.Fourthly,I put forward improvementsolutions of greening problems for Jing Hu and Lian xu expressway.By investigating the situations of the present greening situation and the custody of Jiangsuexpressway,we will know more about the problems of the greening maintenance. From theaspects of greening maintenance technology and management model,we can know about thespecific solutions. Based on the functional requirement of the greening space,I put forward ascientific and reasonable expressway greening maintenance management model.By this study,we can learn more about the requirements of greening maintenance management,and put forwardthe service level of Jiangsu expressway.
