The Study On The Urban Valley Type Of Wetland Landscape Restoration And Reconstruction

Urban valley type of wetland is an important one of the waterfront wetland landscape resources in a city. With the accelerating urbanization rate, because of unscientific development on the urban valley type of wetland, as well as weak protection consciousness, the urban valley type of wetland has been badly damaged, with the shrink of area, the sharply worsen of ecological environment and the quality of landscape resources of this area, which greatly affect the city environment and People’s life quality. In order to protect the landscape resources of urban valley type of wetland and connect people and the urban valley type of wetland, the essay expands restoration and reconstruction on the urban valley type of wetland landscape.The essay has discussed from the definition of urban valley type of wetland, ontology study, landscape restoration and reconstruction goals and principles as well as the method and the way through referring the restoration ecology, landscape ecology, ecological function theory and landscape planning and design theory and other related theories, The study includes the following:1. Referring at home and abroad for the definition of river wetlands and streams wetlands, the essay puts forward the definition of urban valley type of wetlands, summarize the landscape composition and ecological characteristics of the urban valley wetlands ontology.2. Through the related theory researching, this paper proposes the goals should be achieved and the practice principles should be followed about the urban valley type of wetland landscape restoration and reconstruction:The goals of landscape restoration and reconstruction include water cycle health and flood control,the restoration of s(?)cam ecosystem health, creating regional characteristics valley type landscape, enhancing the participation of valley type landscape; practice principles include the system and the regional, multiple objectives into account, dynamic planning, landform protection, ecological planning and cultural heritage.3. On the basis of study about the urban valley type of wetland body, guided by the practice principles of restoration and reconstruction, the essay conclude the contents and the way of urban valley type of wetland landscape restoration and reconstruction from the5aspects of aquatic environment, waterfront, vegetation, cultural, and accessibility, to reach the target of valley type of wetlands landscape restoration and reconstruction.4.As an example of Maan creek wetland Park, through the literature data and field investigation, this paper understand the site environment of planning area, analyze and evaluate current situation of landscape resources. On this basis, through applying above theory and system approach to plan and design the Maan creek wetland Park landscape,it is used to prove the feasibility of valley type of wetland landscape reconstruction and reconstruction methods in practice.5. Summary of landscape restoration and reconstruction methods of urban valley wetland, deficiencies and research prospects.Through the research in this paper, it primarily discusses the restoration and reconstruction of China’s urban valley wetland landscape, which will provide some ideas and technical support for landscape restoration and reconstruction of the same type wetland in the future, and promote sustainable developments of urban valley wetland landscape.
