Study On New Rural Green Space Plant Landscape In Yangtze Delta Region

The greenization of new rural is an important foundation to build a new socialist countryside,it is also an important guarantee to realize the new rural sustainable development,and an important embodiment of new rural style.In order to build the new rural ecological plant landscape, by taking the new rural Yangtze Delta region of jiangsu, zhejiang and Shanghai green space plant landscape as the research object,this paper selected the park green space, waterfront green space, road green space in 12 new rural,and researched its typical plant communities,then selected 400 courtyards,and surveyed greening situation.It used the methods of phytocoenology and AHP to analysis and evaluation of the investigation content,the result shows:(1)In survey of 30 samples, there are 69 species of woody plants, subordinate to 54 genera and 34 families.83.3 percent of the samples of the arbors density are less than shrubs density,evergreen and deciduous plants in the ratio of the amount and type is not balanced, especially the evergreen shrubs shrub layer are predominate in number and variety.(2)Of the 400 courtyards being surveyed,there are 134 species being planted subordinate to 113 genera and 68 families.At present,there has been some green spaces already existed in the courtyards of the Yangtze Delta region,and consideration to appreciation and productive,but the application of the indigenous plants and the diversity of plant species has the potential to be improved, the arrangement patterns should be enriched.(3)This evaluation established new rural green space plant landscape evaluation model, including aesthetic,eco-efficiency,social benefit as criteria layers and 12 evaluation factors. In survey of 30 samples,calculations of the comprehensive evaluation score and landscape quality rank distribution is relatively concentrated,but cannot yet reach a high level.(4)According to the status of Yangtze Delta region green space plant landscape, some specific suggestions were proposed. It recommended for 45 species of indigenous tree available for use and formed 25 of artificial arrangement patterns for application,in order to build the beautiful plant landscape in new rural.
