| Under the background of rapid global climate change,the impact of disasters in every city is irreversible,and will eventually spread to the world in the form of butterfly effect,so the protection of the global environment has become a key topic of concern.As a part of the ecosystem,urban wetland is not only the habitat of many organisms,but also plays an important role in replenishing groundwater,flood storage and drought prevention,regulating flow and urban microclimate,which plays an important role in urban ecological environment.With the promotion of planning concepts such as elastic concept,sponge city and low impact development,it also provides feasible ideas for the development of urban wetland: the development of the city requires wetland landscape to provide necessary ecological services,while avoiding the damage of ecosystem when wetland provides corresponding functional services.The concept of flexibility makes wetland ecosystem can be repaired by using its own system when it is damaged,so that the whole system can be maintained in the state of normal function as much as possible.Based on the analysis and arrangement of the current situation and long-term development process of wetland,it can be found that the rapid and static design has been unable to meet the development of urban wetland,and it is necessary to pay attention to the ecological benefits and have comprehensive functions to meet human activities.Starting from the interaction between the design of ecological environment protection and human activities of AI Sihu wetland in Nanchang,combined with the current situation of wetland parks at home and abroad and the current problems faced by AI Sihu wetland in Nanchang,this paper makes a preliminary study on the concept of flexible landscape through multi-disciplinary research methods,summarizes the strategy of urban wetland landscape design,and puts forward the corresponding design for the possible problems The principles and methods provide the basis for the ecological restoration design of AI Sihu wetland,and are committed to solving a series of problems and crises when the wetland is faced with natural disasters.In the design process,the current landscape,the latest upper planning and the surrounding environment within the scope of AI Sihu wetland are analyzed,and the existing problems of AI Sihu wetland are found.The design concept is based on the elastic concept,the design elements of wetland landscape are analyzed and sorted out,the overall layout and multi-functional zoning are carried out,and the water quality and plant allocation are carried out according to the characteristics of each region Special designs such as placement,revetment,pavement and landscape sketch,etc.shall be carried out to analyze the specific methods to solve the problems with pictures or models.Through the flexible concept design,we can improve the vitality and diversity of wetland ecosystem,enhance its ecological recovery and self-regulation ability,improve the spatial layout of AI Sihu wetland,and build it into an urban wetland integrated with ecology,leisure,culture and education. |
