Research On The Coordination Of Ecological Function And Recreational Function Coupling In Urban Wetland Parks And Optimal Design

Urban wetland parks are a good medium for contacts and wetland natural environment,along with the development of China’s urbanization process,the number of urban wetland parks is also growing rapidly,so how to seek a harmonious relationship between "quantity" and "quality" in the construction of urban wetland parks is a key concern for the construction and management of urban wetland parks in the future.The relationship between "quantity" and "quality" in the construction of urban wetland parks is a key concern for the construction and management of urban wetland parks in the future.As a complex synthesis of ecosystem and social system,the level of construction and development of urban wetland parks depends on the degree of coordination between internal ecological elements and service functions.At present,the construction of urban wetland park evaluation indexes lacks research on the correlation between the internal systems of the park,so a coupled coordination model is introduced to measure the interaction between ecological and recreational functions,which can also reflect the overall quality level of wetland parks,in order to provide new ideas and methods for measuring the construction and development level of urban wetland parks.Based on relevant research results at home and abroad and the current situation of urban wetland park construction,this paper constructs a coupled and coordinated evaluation system with 29 indicators in 11 levels,including habitat support function,biodiversity conservation function,carbon sequestration function,recreation space,landscape elements and service facilities,and classifies them into levels.The study analyzes the coupling and coordination degree of ecological and recreational functions within the three urban wetland parks in Nanjing in 2022,analyzes the main factors affecting the coupling and coordination degree of urban wetland parks and the problems of construction,proposes corresponding landscape optimization design strategies,optimizes the design transformation of the park with the worst construction development level,and provides case references for the construction of other urban parks.The results of the study show that:(1)the three urban wetland parks in Nanjing are ranked from highest to lowest in terms of coupling coordination: Nanjing Yuzui Wetland Park,Pukou Jiangtan Wetland Park,and Sanqiao Wetland Park;(2)what affects the overall construction development level of Sanqiao Wetland Park is the recreation function system,the quality of the park’s water body,internal traffic fluency,the type of recreation space,plant landscape,cultural display,trash cans,resting(3)According to the strategy to optimize the design of Three Bridges Wetland Park,the macro-level optimization of the scope of zoning,sorting out the traffic flow,the meso-level landscape space to take the "three axes and ten spaces" layout form,micro-level optimization of the quality of landscape elements and basic At the micro level,the quality of landscape elements and the quantity and layout of basic service facilities are optimized.(4)In conclusion,some urban wetland parks in Nanjing do not pay enough attention to the recreation function,and the gap between the quality of ecological environment and the quality of services and recreation is large,resulting in a low degree of coupling and coordination,and it is necessary to pay attention to improving the social service function of wetland parks in terms of recreation and popularization of science and education on the basis of protecting ecological resources in the future.
