Study On The Spatial Pattern Of Artificial Wetland Bubble Based On Ecosystem Health Assessment

Since China's accession to the Convention on Wetlands in 1992,wetland research and protection has received increasing emphasis on research and government departments.However,relative to wetland research in other areas,wetland landscape research or its new force.In recent years,the study of urban wetland park has gradually developed into a new area of concern.Urban wetland park refers to "into the urban green space system planning and suitable as a park of natural wetlands,through reasonable protection and utilization,the formation of protection,science,leisure and other functions in one park",embodies the ecological benefits of wetlands,economic and social benefit.Urban wetland park is an emerging field in our country.In the process of construction of urban wetland park in our country,the design of wetland is the key.In this paper,by studying the advantages and disadvantages of natural wetland and the advantages and disadvantages of artificial wetland,And the advantages of the combination of artificial wetland park in the optimal artificial water wetland,the ecology of the edge effect theory and artificial wetland water purification principle of integration,and finally derived the optimal artificial water wetlands that artificial wetland bubble Spatial pattern,and the actual case of wetland ecosystem health assessment and correction,improve the artificial wetland bubble theory,for its broader application in the field to lay the theoretical basis.In this paper,the study of artificial wetland bubble in urban wetland park is divided into six parts.The first chapter is the introduction,the research object,and the research background,method,purpose,meaning,content and framework to sort out.The second and third chapters summarize the research on wetland and artificial wetland,the research of urban wetland and urban wetland park,and summarize the current situation and problems of the development and construction of domestic urban wetland park.In the fourth chapter,the advantages and disadvantages of natural wetland and artificial wetland are combined,and the concept of optimal artificial wetland is put forward.Based on the theory of wetland research,the ecological ecology of ecological ecotone,The paper puts forward the theoretical pattern of artificial wetland in urban wetland park.In the fifth chapter,the paper summarizes the research and theory of domestic wetland evaluation,constructs the artificial wetland evaluation system of urban wetland park based on ecosystem health assessment,and selects Tianjinqiao Garden as the research object to carry out field investigation and wetland health evaluation.In the sixth chapter,the artificial wetland bubble landscape of Tianjin Bridge Garden is studied in real time,and the wetland ecosystem health assessment of artificial wetland bubble pattern is carried out,and the theoretical pattern of artificial wetland bubble is compared.The seventh chapter is the conclusion of the article,summarize the research content of the paper,put forward the development direction and prospect.This article in terms of innovation: 1.Analyze the advantages and disadvantages of the traditional constructed wetland by summarizing the research and development of wetland and constructed wetland and urban wetland park,and put forward the concept of optimal constructed wetland;2.Combining with the principle of landscape ecology,this paper puts forward the spatial pattern of artificial wetland bubble theory based on edge effect;3.Review the relevant wetland evaluation study,construct the evaluation index of urban wetland park,and propose the artificial wetland bubble evaluation system based on ecosystem health;4.Based on the results of health assessment,this paper compares the actual pattern of artificial wetland bubble with the theoretical pattern,and revises the theoretical pattern of artificial wetland bubble and discusses it.
