Importance of Urban Wetland Parks under the Development of Green Healthy Cities: A Case Study of Nanjing City.

Wetlands are widely distributed all over the world, and have many wildlife resources, which are the main pieces of the puzzle for natural resource conservation and sustainable development on earth and have important irreplaceability. In this paper, through questionnaire survey, field research, literature review, etc., importance weight analysis was conducted by using principal component analysis, and field survey and questionnaire were carried out to collect data on ecological environment function, environmental protection function, landscape beautification function, disaster prevention and mitigation function of urban wetlands. The problems in wetland parks of Nanjing were discussed, such as lack of awareness of landscape planning, deficient late management of wetland parks, weak ability of sustainable development, and unreasonable landscape layout and function. Finally, corresponding solutions were proposed, such as adhering to the planning and design of urban wetland parks with green as the base and health as the basis, persisting in the construction of a wetland system with high biodiversity and near-natural characteristics, adhering to the principle of sustainable development, adopting the construction idea of symbiosis and circulation of urban wetland parks, strengthening education and publicity work, and paying attention to the organic combination of system protection and coordinated construction. The research can build a new development direction for the model of urban wetland parks and green healthy cities, and provide theoretical support for urban sustainable construction.
