Investigation On Waterfront Greening Situation And The Plants Scenery Design In Jinan City

The main subjects of study for this article are the landscape of waterfont plant in Jinan, and the field research approach to 11 kinds of waterfront survey as the method. The study included landscape composition of plant species, growth conditions, community structure, and application ways. Then we calculated for each frequency, analyzed the situations and problems of plant status used in landscape tree species.The surveys showed that 140 waterfront plants belonging to 53 families were applied. There included 96 woody plants and 44 species of herbs. Most of the parks and riverside green space composed waterfront communities and plant communities in the shore communities from the revetment. There were abundant water plants only including Daming Lake, Lotus Springs, Park Springs.By frequency analysis, we found that the common weeping species includes Salix babylonica, Cedrus deodara, Pinus bungeana and Platanus orientalis. In most cases Salix babylonica were the dominant and abundant species, and it caused that landscape plants was monotony and similar. We also found that some species were not tolerant for water wet, but a large number of them were used and in poor growth. Some growth conditions well and excellent ornamental tree, such as Ulmus pumila, Koelreuteria paniculata ,Catalpa speciosa, Acer truncatum Bunge, Melia azedarach , Populus simonii were seldom used; bush layer of water-wet application of rare species, other available species included shrub Hippophae rhamnoides , Tamarix chinensis, Elaeagnus angustifolia, Punica granatum , Rosa, Amorphafruticosa, Hibiscus syriacus and so on. Nelumbo nucifera, Nymphaea alba, Hydrilla verticillata were commonly used as aquatic plants. Ragweed, few types of applications, was founded as invasive plant. Lythrum salicaria , Scirpus validus , Iris tectorum, Typha orientalis , Acorus calamus , Arundo donax var. versicolor , Cyperus alternifolius, Pontederia cordata , Marsilea quadrifolia should be applied. Radix and bluegrass were dominant species in the use of ground cover plants. Some flowers were applied in the new scenic view which enriched the landscape level. But some of the early scenic spots were monotonous, duplicated and bad landscape effects.There were 3 plant community structure types in jinan waterfront landscape plants, included'Arbor and herbage'structure,'Arbor and shrub'structure and'Arbor, shrub and herbage'structure. There were large proportion of the'Arbor, shrub and herbage'structure, but only a few Arbor and shrub plant were applied with high repetition rate. The plant configuration was monotonous, duplicated, disordered and other problems.Based on the landscape status of waterfront greenland in jinan, it recommended 27 models of plant arrangement suitable for different waterbodies(lake,river,spring,pool ,fountain) or different ecological conditions (water tolerant, water tolerant extremely, alkali and water resistance)according to select and summary .. And we also studied the common plant configuration in dike, Island, bridges, embankment and road. Finally, based on the field research and literature, we sumed of problems of Jinan City waterfront landscape plant, suggested that it should make full account of its characteristic plants and combine with historical context, increase the types and quantities of aquatic plants, be rich in plant configuration mode, and control invasive alien species and so on.
