The Hydrophyte Landscape Design Of Rosebay, Qingxiu Hill, Nanjing

Qingxiu mountain scenic area is a "green kidney" of Nanning, and it plays an important role and gets a significant position in the society, economy and ecological environment construction. The construction of Qingxiu mountain scenic area is an essential decision to protect the ecological environment and plants, to build forest landscape, to protect human survival conditions and to develop the mountain’s ecological benefits, social benefits and economic benefits sufficiently.In the new plan, the watercape of Qingxiu mountain scenic area is an important part of it and depends on the aquatic plant landscape as an important way of expression. We should understand the general situation, the data classification, growth environment factors and the function of aquatic plant resources, and then to grasp the characteristics of the aquatic plants. In other to lay a foundation for the design of aquatic plants, combinating the analysis of three domestic successful cases,we also need to research the principle of aquatic plant landscape and its planting form and using methods in different water bodies.After reserching aquatic plants in the Nanning Qingxiu mountain scenic area and summing up the existing local aquatic plant situation, types, phenology, design and color, etc. There are18families and23genera and27species of aquatic plants, including19kinds of a water plant, two kind of floating plant, three kind of floating plant, three kinds of submerged plants in Nanning. Most of it are perennial aquatic plants and have numerous color and its’main ornamental period time is between4-9months and its’height is between0.2to2.3m. Through the analysis of existing species, in the mountain rose bay water system design, selection of14kinds of dominant species, appropriate to add some new varieties, to enrich the composition of the aquatic plant landscape. Water system in this paper, we study the rose bay, planning and design the water system is divided into, view of Wang Lianchi, fish pond and lotus pond heron creek, rose bay, most valley, wild duck creek, reeds eight bodies of water. In the overall ecological communities stability under the premise of unification, each district has unique aquatic plant community, rich species diversity, richness of as much as possible. Aquatic plant cultivation way has natural type, container planting, planting bed planting, planting form has a plant, groupings, clump planting, avenue system, points, etc. Using a variety of planting technique, the reasonable collocation of plant species, build natural changing ecological landscape. Internal drainage with spots of different aquatic plants landscape, through the detailed waterscape of aquatic plant seed selection, configuration methods, although the effect and the usability, which reflects the important effect of aquatic plants in the landscape, and rich in function. We should not only pay attention to the cultural connotation and aesthetic ornamental effect, but also attaches great importance to the ecological performance, and need to maintain the ecosystem balance and persistence. This paper selected the five aquatic plants landscape design that are some classic cases owning special characteristiacs to research, and analyzed the design methods of different themes about aquatic plant landscape, the selection of plant species and the analysis of aesthetic effect.
