The Preliminarily Exploration On Landscape Construction Of Constructed Wetland

Constructed wetland, which is the artificial wetland, does not only have the functions of decontaminating sewage, reforming the environment, promoting the quality of the landscape, etc, but also be an emollient complement for the conservation of nature wetland that worthes being popularized. Lately, the wetland landscape construction is becoming an important component to the constructions of urban environment and the urban sewage treatment system. From the perspective of the Landscape Architecture Designer, there is a certain amount of theoretical significance and practical value on constructing the combination of ecological effects, landscape aesthetic value and economic value for the constructed wetland landscape, in particular on creating the constructed wetland plant landscape.Based on having read a great deal of articles and dissertations, investigated the constructed wetland landscape in some typical wetland parks, summarized some present research domestic and abroad, this dissertation has put some related theories such as ecology, landscape aesthetics, artificial plant landscape, etc, into the landscape creations of constructed wetlands. As a result, it has put forward that the constructed wetland landscape is made up of three factors:ecological landscape factor, human civilization landscape factor and the artificial landscape elements. And it also has pointed out that there are six characteristics- ecological characteristic, natural characteristic, thematic characteristic, special features, tractility and limination in constructed wetland landscape. Besides, this research aims at finding out the landscape beauties, and the result is that there are seven beauties in constructed wetland, which including the ecological beauty, natural beauty, configuration beauty, colorful beauty, dynamic beauty, artistic conception beauty and the phonological beauty. Meanwhile, this dissertation has pointed out that the constructed wetland landscape is made up of seven types:the waterfront landscape, plant landscape, animal landscape, nature phenomena landscape, science-popularized landscape, humanity landscape and the horniness landscape. For the further study, this dissertation has focused on how to construct a beautiful and economy-valued ecological wetland landscape, eapecially on what the constructed wetland plant landscape is and how to create an ecological and beautiful constructed wetland plant landscape. And it has suggested that after having analyzed some typical plants in the following four communities-the submerged macrophytes community, the floating-leaved macrophytes community, the emergent macrophytes community and the marshy plants community, we should follow the five plants-selected principles that including strong purification principle, suitable local species, the strong resistance, ornamental aesthetic principle and the economic principle. It also advanced that the six artificial plants notices as followed:ecological principles, unitary principle, technology principle, artistic principle and the principle of sustainable development should be adopted. Finally, based on the aposteriori theories above and the present conditions in "Sanyang", this dissertation has taken out some suggestions on the wetland landscape construction, in particular to the construction of its plant landscape and its horniness landscape.This dissertation attempts to help us understand the constructed wetland landscape and its beauties much more clearly and definitely, better to creating the constructed wetland landscape perfectly, especially on the construction of plant landscape for constructed wetland. Furthermore, this dissertation endeavours to provid a theory service for the ecosystem constructions in constructed wetland and being better for the constructions of urban wetland garden.
