Research On The Social Value Evaluation Of Ecosystem Services Of Nanhu Park In Changchun City

In the value assessment of natural ecosystem services,the assessment of social value of Ecosystem Services occupies a crucial position.Traditional value assessment of ecosystem service mainly focuses on economic,and the assessment results are expressed in the form of monetization value,but less attention is paid to social attributes and spatial heterogeneity.Along with the deepening of the research on Ecosystem Services value,people generally recognize the need for social value information which provide environmental management trade-offs to the public and policy makers,but there is often a lack of consideration of social value in Ecosystem Services ’evaluation.Social value which specified in the decision-making process is often measured by qualitative indicators,quantitative indexes are given priority with monetary market attributes.However,the indicators that can represent social value are not all monetary indicators.This paper takes Nanhu Park In Changchun City as the research object,and based on the SolVES model,the social value model of Ecosystem Services,which to evaluate the social value of the park’s ecosystem services,and then the social value is quantified and implemented in space.First,use the social value model in the SolVES model to select the interviewee group to determine the position of the highest social value.The order of the social value types of Nanhu Park In Changchun City is aesthetic value> leisure and entertainment value> sports and fitness value> history Cultural value > biodiversity value > economic value >education value > spiritual value > therapeutic value;secondly,through the statistical processing of the results which come from the questionnaire,and combined with the requirements of the SolVES model for the survey subgroup data to select the relatively high value index.The first four types of main social value types: aesthetics,leisure and entertainment,sports and fitness,and historical and cultural values.From the perspective of tourists(visitor age and source),the impact on the spatial distribution of the four main types of social values is studied,and environmental elements(road elements,The level of water element)studies the relevance of the four main social values.Finally,discussing how to improve the social value of the park’s ecosystem services from the perspective of social value perceived by the public based on the assessment results.This study aims to use SolVES model evaluation methods,to learn the public perception of social value of Ecosystem Services and preferences and combined with the planning and design methods to enhance the social value of ecosystem services,which in order to provide planning and design of new train of thought to city park in urban park planning for the future,to provide planning and design of new train of thought for the urban planner and landscape architect,to provide theoretical basis and technical support for the urban construction related departments in promoting the value of ecosystem services of social strategy,to provide the model for other city park construction of ecological civilization in China.
