The Research Of City Plant Landscape Restoration Technology And Quality Evaluation System

With the modernization and exploitation of big cities, obvious degradation of city ecosystem and series of environmental problems occurred since reform and opening up of China in 1978. These problems include air pollution, noise pollution, traffic jam, short of soil and water, deposits of garbage etc. These problems have been the focus of city attention and the expert pointes out that if environmental problem was not handled well, it will be a time bomb of Harmonious Society in China. Therefore, resolving the contradiction of development of cities and city ecosystem is the key project to explore in Chinese science society, also it is a practical problem facing up to every city in China.Through more than 20 years endeavor, Zhujiang River Delta depended on the advantages of geographical features, personality and policies, and society and economy developed super normally, then the Delta became into the area which is the fastest area in economic development and the highest area in city modernization in China. However, environmental and pollution problems of Zhujiang River Delta have been a restricted factor to the social and economical development of the Delta. To resolve the historical environmental problems and the environmental problems in the process of regulating the development is still a long-term and arduous task.Therefore, this paper looked back the Eco-Restoration and the developmental process, theoretical basic, research situation and research tendency of restoration ecology firstly. Secondly, general situation and plant landscape situation of Zhujiang River Delta were analyzed comprehensively. On the base of this situation restoration methods and evaluation system of Zhujiang River Delta were studied deeply and the following are the major achievements:1. Richness of the theory of city plant landscapeIdentification function of plants was regarded as an important rule and index of the construction of city plant landscape at the first time. Identification function of plants is a fire-new conception and it enriches the theory of city plant landscape infinitely.On the base of previous research results, conceptions of landscape, city landscape, city plant landscape, landscape pressure and landscape scale were analyzed deeply, and new principle and new technique to construct city plant landscape were presented.2. Analysis of the status of city plant landscape in Zhujiang River DeltaThe main representations of city plant landscape in Zhujiang River Delta are few...
