Investigation On Waterfront Plant Resources And Analysis And Evaluation Of Landscape In Nanchang City

This paper made a study of waterfront plants and the landscape around them, through field research of nine major waterfront green space in Nanchang City, analyzed the species composition and application characteristics,community types and configuration mode,landscape space type and characteristics of them. Then made a comprehensive evaluation for the landscape quality of them by Analytic Hierarchy Process, which can provide reference for the optimization of the waterfront plant landscape in Nanchang. The main results were as follows:(1) The species of waterfront plant in Nanchang city is abundant, with 211 kinds of waterfront plants which belonging to 140 genera in 78 families. Among them, there are 62 kinds of the arbor plants, accounted for 29.4%, 69 kinds of the shrubs plants, accounted for32.7%, 7 kinds of the vine plants, accounted for 3.3%, 24 kinds of the aquatic plants,accounted for 11.4%, 39 kinds of the plante plants, accounted for 18.5%, 10 kinds of the bamboo, accounting for 4.7%. The plants of Rosaceae, Poaceae, Fabaceae, Oleaceae,Asteraceae are widely used in landscape application. The native plants with strong adaptability and manageable are frequently applied, such as Cinnamomum camphora, Salix babylonica, Taxodium ascendens, Cerasus yedoensis, Koelreuteria paniculata. Most of them are the summer flower plants with good growth conditions.(2) The types of waterfront plant community in Nanchang city could be divided into aquatic plants community, revetment plants community and shore plants community,including 7 configuration models of plant community. The configuration models of the revetment and shore plants community are rich and colorful, the plant community combined with the arbor, the shrubs and the plante accounts for a large proportion, its landscape space level is significant. The configuration form of the aquatic plants is single with poor landscape effect.(3) The landscape space form of waterfront plant in Nanchang city are mainly simple-type space with little changes. Concluding“?”pattern,“?”pattern, liner pattern and Belt pattern. The linear combination pattern take a big proportion in the composed-type space, most of them are repeated, the whole landscape effect is poor.(4)The paper select 10 evaluating indicators about landscape, ecological benefit and service quality. And has constructed a complete evaluation system to evaluate the quality of 65 typical plant landscape in Nanchang city. The results showed that the quality of waterfront plant landscape below the average levels, needs to be improved.Among them,there are 6 plant communities on the first grade, accounted for 9.2%, 20 plant communities on the second grade, accounted for 30.8%, 39 plant communities in total under the third grade, accounted for 60%. The plant community combined with the arbor, the shrubs andthe plante has a high quality,as well as the aquatic plants community has a low quality.(5) The paper made an analysis on the problems existing in the landscape of the waterfront plants, and put forward the corresponding suggestions about landscape promotion.
