| Modern plant-landscape of road-greenlands in urban areas is a true reflect about the productivity development,the taste about beauty,the custom,the face of spirit,the culture of civilization and the level of morality of a city or a certain areas. Now, plant-landscape of road-greenlands has been a necessary part of our life. It also has been the directest part to affect people's health and maintain city's ecosystem. It linked parks,road-greenlands,living areas,beauty spots and so on to a whole and made plant-landscape of road-greenland take a very vital role to play in urban ecosystem. Therefore,making use of the road system sets up a city's a green gallery, improves the whole greenland system, services for the residents, having the strategic meaning of very importance.Integrating the theory with the practices and developments of urban plant-landscape of road-greenland, the old urban area and the new area of Nanjing were studied in this paper, and 110 non-main road-greenlands were investigated. Carried on a great deal of spot inquisition, data collections and analysis, this paper analyzes its present condition in landscape, community and plant colony. With the theories of Ecology, Aesthetic, Landscape, Environment, Botany and so on, the model is established. And from appreciate characteristic angle to analyze the characteristic of the ornamental. And made comprehensive contrast evaluation with living districts,campus and park roads. The main results are as follows:â‘ In the residential district and the commercial district in Nanjing urban areas, the plant species are not abundant and are short of multiplicity. However in these two areas the indigenous plants are lack, and the plant-landscape of road-greenlands is similar, for a few species are applied abroad. The ecological results and the ornamental value of the non-main road greenlands in the residential district are better than the commercial district. However, the level arrange form of the residential district and the commercial district are very similar. Most of them are made of one plat surface and two greenlands. The structure of plant-landscape of the road-greenlands in these two districts are not abundant, and the form of the plant-landscape are both monotony.â‘¡In the aspect of the ornamental characteristic, the species of the flowers is more abundant in residential district ,and the margin of bush species among them are the best of all. The species of the fruits in these two road-greenlands are very similar,both of them are lackness. The amout of the fruits species in residential districts are better than the commercial districts,but fruits species of the layer which is the nearest to the ground lack seriously;The application frequency of foliage plants in these two districts are both high,but the amount of species are monotony.â‘¢From the contrast of these evaluate elements in five kinds of road samples,totally to say,gardens are the best among these samples,the quality of landscape of other samples have crossovers; In the end of the article, the characteristic of plant-landscape of non-mian road-greenlands in Nanjing urban areas was summarize,and the priniciple of the landcape greening was discussed,and the development suggestion to plant landscape of non-main road greenlands was given, and some advices were brought forward to build ecological, local, special plant-landscape of road-greenlands.
