Evalution And Optimal Design On Vertical Plant Landscape Of Purple Theme Park In Nanjing

In recent years,the vertical greening is widely used in city parks,not into a variety of forms,also can increase the park landscape art effect,beautify the environment,make park greening more lively,and effective use of land resources,afforestation rate high,fast effect.In this paper,eight city theme parks in Nanjing as the research objects,the vertical greening in eight park sample application type,plant configuration mode,of plant species,plant growth,plants use frequency,aromatic plants and the seasonal characteristics,ornamental characteristics of field investigation,summarizes status of three-dimensional analysis of Nanjing eight parks,secondly,using the analytic hierarchy process(AHP)to 20 samples of comprehensive evaluation of plant community landscape including ornamental plant landscape characteristic,ecological quality and the social efficiency three aspects.Finally based on this,puts forward and summarizes promotion theme park,Nanjing city three-dimensional green’s advice.The research content and conclusions include the following aspects:1.Through to the eight theme park 124 sample plots of field survey and data statistics,it can be seen that the theme park,nanjing city stereoscopic landscape type diversity,plant abundance,and most plants using the frequency is relatively low,using the high frequency of single plant species.Vines collocation with Joe,irrigation,herbs planting,plant configuration mode diversity,distinct.2.Through the investigation of sample area,summary it is concluded that using stereo greening plants 73 families,121 genera and 157 species,including application more concentrated in the rosaceae,liliaceous,oleaceae,apocynaceae,cupressaceae,compositae,gramineae,moraceae,caprifoliaceae,etc.58 kinds of 30 species of trees,shrubs,vines,17 kinds of herbs 52 species.In Nanjing vertical greening plants,the uneven distribution of shrubs and herbs,shrubs,herbaceous,least vine.3.Research park in the form of stereo virescence mainly includes the metope greening,greening corridor greening,crawl,fake rocks greening,slope protection afforestation,three-dimensional green flower bed.By analyzing the different forms of plant configuration mode,summarizes the common typical plant configuration mode.4.From plant leaf color and color features of design and color,fragrant characteristics,the seasonal variation characteristics from three aspects to discuss different ornamental characteristics of landscape plants in Nanjing,the application of the eight stereo greening landscape theme park.Rich three-dimensional greening plant landscape is the key to reasonable collocation of different plants of ornamental characteristics.5.For stereo greening fully investigation,eight park from 124 sample plots of 25 sample as evaluation objects,using the analytic hierarchy process(APH)to construct the three-dimensional greening plant landscape evaluation model,comprehensive evaluation was carried out on the sample,it is concluded that the landscape for comprehensive quality order.This article through to the eight theme park stereo greening plant landscape research and evaluation,stereo virescence construction ring theme park in Nanjing is optimized transformation strategy at the same time,according to different forms of greening,and puts forward his own optimization design,created for the theme park of Nanjing after the three-dimensional landscape reference and Suggestions are put forward.
