Research On Zhengzhou Urban Artificial Plant Community Features And Landscape Evaluation

In this paper, as Zhengzhou City Park artificial plant communities for research object, select 115 artificial plant communities typical of the city’s eight parks survey has been conducted on the species composition of plant communities, plant sources, plant community types, vertical structural level, community landscape appearance characteristics, species diversity were analyzed system. And use of AHP from ecological functions, spatial structure, visual quality, and service of the four aspects of social choice 16 evaluation factors, establish a reasonable evaluation system, and analysis of species composition,distribution characteristics of the grade I plan in the 5 parks. Finally, Based on the investigation of the results and the comprehensive evaluation quality of artificial plant community landcape, put forward the science reasonable optimization measures for artificial plant community of Zhengzhou city park.The main results are as follows:1. Species composition. Through eight parks in Zhengzhou survey 153 vascular plant species, 120 genera and 63 families. Among the most abundant species of tree, 57 species, 49 kinds of shrubs, 41 kinds of herbs, plants like vines at least a total of six kinds. According to "Chinese Vegetation" in the plant community classification principles, the 115 plant communities will be divided into 8 vegetation types, 57 of which deciduous broad-leaved forest, coniferous and broad-leaved mixed forest 18, 15 evergreen coniferous forest, 14 evergreen deciduous broadleaf forest, 5 evergreen broad-leaved forest,2 deciduous coniferous forests and bamboo forest 1.2. Species richness. Each park species richness order: botanical garden>Green Garden>People’s Park>Bayside Ridge Park>Forest of Zhengzhou>Bauhinia parks> Wetland>Forest Park. Different types of artificial vegetation abundance order: evergreen and deciduous broadleaf forest>conifer>deciduous forest>evergreen coniferous forest>evergreen broadleaf forest>deciduous conifer forests. Vertical structure type richness order: grass bushes and trees>bushes and trees>shrub and grass>Joe grass.3. Species diversity. Simpson index and Shannon-wiener index performance diversity basically the same, each park tree diversity indices are above 0.35, the highest for the Botanical Garden. The evergreen and deciduous broad-leaved forest is highest in different types of community diversity index. Different structure types, tree, shrub and grass highest diversity index structure. Each park evenness index between 0.3 and 0.91, evenness park grass sort of bushes and trees: the tree layer>shrub layer> herb layer. The evenness index and diversity index of tree layer is to sort same in different community. Vertical structure type of tree layer evenness index was the highest type of tree, shrub and grass.4. Landscape Evaluation. Use AHP method on artificial plant community landscape 115 comprehensive evaluation, The conclusion that grade landscape has a total of 9 accounted for 8%, II, III grade landscape consists of 94 accounted for 82%, IV grade landscape has a total of 12 accounted for 10%, Description Zhengzhou City Park on artificial vegetation integrated landscape in the middle level, from the whole, a higher level of quality comprehensive view of the Botanical Garden and People’s Park, the worst forest park.5. Landscape optimization measures. From landscape optimization measures proposed reflect when Distinctive Landscape, eco-efficiency, strengthen landscape ornamental, rational introduction of plant resources, etc.Through the statistics and analysis of artificial plant communities in Zhengzhou city parks, and landscape evaluation for park plant, provide reference and theoretical basis for the later construction local characteristics and stability of artificial plant community.
