Research On Road Greening And Landscape In Urban Area Of Changyi City

With the development of cities, the material level of people’s life has been improved. The urban roads and the environment become more and more important, and the urban green is also an important symbol of city environmental quality and the embodiment of all of urban green landscape. According to the research of ornamental plant species, ornamental elements, hue, seasonal, application status, plant disposition, varieties, the author analyzed the current greening landscape condition of 17 roads of Changyi city by means of spot check in field survey and evaluation, Some problems and suggestions of the currently greening were proposed, provide references to the construction of road greening to Changyi city, and made foundation of the development of constructing eco-green city in landscape, ecology and other aspects The results were as follows.(1) There were 159 kinds of species, belonging to 104 genera and 55 families. Rosaceae with the most species of 32 belonging to 19 genera, oleaceae followed, including 11 species belonging to 6 genera, the third is legumes with 9 species belonging to3 genera,29 families had only 1 species, such as ginkgoaceae, simaroubaceae, calycanthaceae, brassicaceae, araceae, amaranthaceae, polemoniaceae and so on.(2) There were 159 species of plants, belonging to belonging to 104 genera and 55 families. Trees>shrubs> ground cover plants, including 129 species of woody plants with the proportion of 81.1%,30 species of herbal plants with the proportion of 18.9%,81 species of trees with the proportion of 50.9%,41 types of shrubs with the proportion of 25.8% and 7 types of lianas with the proportion of 4.4%.(3) When statistics evergreen and deciduous plants only were remembered the premise of woody plants,26 kinds of evergreen species and 103 kinds of deciduous trees are in woody ornamental plants, deciduous trees> deciduous shrub> evergreen trees> evergreen shrub> deciduous vine> evergreen vine.14 kinds of evergreen trees with the proportion of 8.8% in total road greening species,10.8% in woody plants, and 53.8% in evergreen plants, and 53.8% in trees,67 kinds of deciduous trees with the proportion of 42.1% in total road greening species,51.9% in woody plants, and 65.1% in deciduous plants, and 82.7% in trees.11 kinds of evergreen shrub species and 30 kinds of deciduous shrub were in woody ornamental plants, evergreen shrub with the proportion of 6.9% in total road greening species,8.5% in woody plants, and 4.2% in evergreen plants, and 26.8% in shrub,30 kinds of deciduous shrub with the proportion of 18.9% in total road greening species,23.3% in woody plants, and 29.1% in deciduous plants, and 73.2% in shrub.1 kinds of evergreen wine species and 6 kinds of deciduous wine were in woody ornamental plants, evergreen wine with the proportion of 0.6% in total road greening species,0.8% in woody plants, and 3.8% in evergreen plants, and 14.3% in wine,6 kinds of deciduous wine with the proportion of 3.8% in total road greening species,4.7% in woody plants, and 5.8% in deciduous plants, and 85.7% in wine.(4) Ornamental characteristics of garden plants in road greening in Changyi were analyzed, the results showed that 56 species were mainly watched by flower,35.2% in total road greening species, Small trees and shrubs are 32 species with the proportion of 20.1% in all, Shrubs> small trees> tall trees,56 species are mainly watched by fruit,15.7% in total road greening species, there were 25 species of the plant flowering in early spring,15.7% in total.(5) The configuration of the greening trees were as followed,① single large arbor,② arbor+ground cover plants, ③arbor+shrubs,④arbor+small trees+shrubs, ⑤arbor+ shrubs+ground cover plants,⑥ small arbor+shrub+ground cover plants, the greening of Changyi city was better than the same city, In addition, we made a detailed analysis of the representative road.(6) It showed that there were three types of cross section of road-greenbelts and they included one board and two belts, two boards and three belts and other (one board and two belts complexed or two boards and four belts), the type of one board and two belts was more than the others, respectively with the proportion of 88.2%,5.9%,5.9%.(7)The greening of the road had many problems, such as, the species of the ground cover plants was not rich, loess exposed, high similar of road landscape plants and plants, big difference of management between the greening road, relationship among the local culture, landscape and plant culture, little vertical greening and three-dimensional greening, and single form of road section. According to the analysis of greening some problems were proposed.
