Study On Landscape Ecological Planning And Design Of Wetland Park In Qinghai-Tibet Plateau

Wetland is the transition zone between water and land,and is one of the three major ecosystems on the earth.In our country,wetland types are diverse and its distribution area is wide.Among them,wetland distributed in Qinghai-Tibet Plateau is a rare wetland type.With the development of society,due to the impact of rapid population growth and overloading of animal husbandry,the wetland in the Qinghai-Tibet Plateau has experienced problems such as the rapid decrease of forest vegetation,the increase of desertification area in fields,the sharp decline of wetland biodiversity,etc.The emergence of these problems has made human beings begin to pay attention to the ecological planning of the wetland in the Qinghai-Tibet Plateau.Through the protection in recent years,remarkable achievements have been made.In the exploration of wetland protection,people found that the construction of wetland park is a successful mode to solve the contradiction between wetland and people.Therefore,the main goal of the construction of wetland park in Qinghai-Tibet Plateau is to use plateau wetland park as a flood control and drought relief and climate regulation,to alleviate the water resources problem in the process of human development,and to give full play to other comprehensive functions of wetland park.However,at present,the planning and construction theory and practice of wetland park in Qinghai-Tibet plateau in China are still in a bottleneck state,lacking scientific theoretical research and unable to provide scientific and systematic guidance for the construction of wetland park in an all-round way.In view of the existing problems,this paper uses literature research,induction and comparison,field investigation and other means to analyze and explore the wetland landscape planning in the Qinghai-Tibet Plateau.Firstly,this paper describes the research background,purpose and research status at home and abroad.Secondly,the definition and characteristics of wetland,the concept,types and characteristics of plateau wetland and the zoning of plateau wetland parks are sorted out,so as to have a relatively comprehensive understanding of Plateau wetland.Thirdly,through the analysis of typical cases in China,the differences of wetland park design are found out,which can provide scientific basis for the construction of wetland park.Combining with the related theories of landscape ecology and ecological restoration,the key elements of Wetland Park Design in plateau are extracted.Finally,the planning and design methods of wetland landscape in the Qinghai-Tibet Plateau are verified with practical cases.Through the above discussion and research,this paper puts forward that in the planning of wetland parks on the Qinghai-Tibet Plateau,we should correctly understand the wetland on the Qinghai-Tibet Plateau,optimize the design strategy by changing the organizational model and structural characteristics of different wetland elements,and design the functional zoning according to the ecological pattern of the existing site,the required use function and landscape form.At the same time,we should recognize the particularity of wetland in Qinghai-Tibet Plateau,pay attention to ecological restoration design,plant community design and water-bank environment design in planning and design,and put forward design countermeasures and suggestions,and put the methods to solve the problems into the design technology level,so as to solve the common problems in the current construction practice of wetland parks in Qinghai-Tibet Plateau,so as to serve as wetland parks in Qinghai-Tibet Plateau.Planning and construction provide theoretical support and technical reference.
