Evaluation And Value Estimation Of Ecosystem Cultural Services In Hefei Huancheng Park

Ecosystem service is an effective way to strengthen the relationship between ecosystem function and human well-being.Compared with ecological services such as regulation,support and supply,cultural services in the ecosystem are more easily perceived and experienced by human beings,and play an important role in increasing human well-being.More and more countries and scholars realize the importance of bringing ecosystem cultural services into landscape planning and management.With the acceleration of the urban process and the increasing demand of the people for a better life,the evaluation system of the ecosystem cultural service of the park around the city is constructed based on the user’s perspective,and the value of the cultural service is quantified,and the spatial distribution characteristics of the cultural service in the park around the city are clarified,so as to better play the value of the ecosystem cultural service of the park around the city.The specific research results are as follows:(1)This thesis sorts out the related concepts and theoretical basis of ecosystem cultural service,preliminarily screens out the evaluation indexes related to ecosystem cultural service according to the characteristics of the park around the city,constructs the evaluation system of ecosystem cultural service of the park around the city through analytic hierarchy process,and determines the weight and ranking of the index factors at all levels to achieve the purpose of quantitative expression.The fuzzy comprehensive evaluation method is used to evaluate the ecosystem cultural service of the park around the city.Based on the fuzzy evaluation method,the evaluation score of the ecosystem cultural service of the park around the city is 3.71,which belongs to a good grade.It is concluded that the park around the city has the highest scores in "recreation" and "aesthetics",which are 4.0751 and 3.9906.Construct an importance-performance analysis model,analyze the supply and demand characteristics of cultural services in the ecosystem of parks around the city,and clearly optimize the effective service supply strategy through responding to the demand.According to the online evaluation text,this thesis analyzes the perception results of the park ecosystem cultural services around the city.The results show that the public has obvious perception of aesthetics,recreation and cultural heritage,and is generally satisfied with the park cultural services,which is consistent with the fuzzy evaluation results.(2)Using the Public Participation Geographic Information System(PPGIS)to analyze the cultural services of the park ecosystem around the city.It is found that the services of parks around the city have obvious spatial differences,and specific cultural services are related to the characteristics of landscape space.Aesthetic services are widely distributed in most areas of the park around the city,followed by recreation and physical and mental relaxation.From the perspective of the synergistic relationship between different types of cultural services,there is a correlation between cultural services.Aesthetics accounts for the highest proportion of all cultural services,with the number of aesthetic labels accounting for 24.3% of all signs,followed by physical and mental recovery accounting for 21.9%.The lowest frequency of educational science popularization indicates that the public has the lowest degree of perception of this service type.(3)Using the Conditional Value Method,based on the public’s willingness to pay,quantitatively evaluate the value of cultural services of the park ecosystem around the city.Finally,it is concluded that the ecosystem cultural service value of Hefei Huancheng Park in 2023 is 290.46 million yuan,which is considerable.Evaluating the cultural service value of the park ecosystem around the city is conducive to the government’s decision-making on the management of public resources,and provides theoretical and empirical support for strengthening the construction of park green space and improving the well-being of citizens.
