The Landscape-oriented Construction Of The Wetlands Ecosystem

In recent years, the construction of the wetlands ecosystem has got more and more public concern. Meanwhile, various problems constantly caused in the construction of the wetlands ecosystem are getting more and more concern. Construction of wetlands ecosystems is a significant project whose functions include water conservation, water purification, micro-climate regulation, flood control and so on.However, with the continuous human intervention on wetlands, wetlands face serious challenges--shrinking, functional decline. Thus, in order to improve the ecological environment of wetlands and maintain the ecological functions of wetlands, people has began to pay attention to restoration and reconstruction of wetlands ecosystem, and utilize the unique functions of the wetlands to conduct sewage treatment and improve water quality. But pessimistically, in the process of wetlands ecosystem construction, a large proportion people overemphasizes the results of sewage treatment and simply conduct sewage treatment which can not meet the purpose of creating the landscape, but on the contrary could cause a second destruction to the wetlands. Therefore, this article focuses on this issue and makes research on landscape creation in the construction of the wetlands ecosystem.First, this article focuses on wetlands development research, relevant concepts, relevant theory research, related concepts of wetlands ecosystem restoration and reconstruction and wetlands landscape.Second, this article introduces how to create landscape in the wetlands ecosystem and how to create it in a natural,harmonious,continuous and stable way without destroying the wetlands ecosystem based on the relevant theory and research mentioned above. These include five aspects as follows: the overall concept, the general layout, engineering construction, plant allocation and spots creation. Given the example of Dianchi wetlands in Yunnan Province, this article will illustrate the landscape-oriented construction of the wetlands ecosystem in details.Finally, this article makes summary and puts forward relevant suggestions and outlooks through analysis of landscape-oriented construction of the wetlands ecosystem. Conclusions include the principles of constructing wetlands ecosystem, fair selection of plants to blend in the water in landscape construction, ecological construction such as revetment, breakwater and basement, protection of the ecology of wetlands systems from destruction, and reasonable use of sewage treatment system which will integrate with the landscape system and provide a complete, beautiful and practical purification system for the people.
