Study On Functional Evaluation And Optimization Strategy Of Wuhan Country Parks Based On Multi-source Data

Under the background of urban-rural integration,planning and construction has shifted from urban interior to urban and rural overall development,and green space recreation has also developed from urban interior to urban and rural recreation system.In the latest green space classification standard,country parks have been changed from "other green space" to "regional green space",and their role in the green space system has also been changed.Wuhan first proposed the construction of country parks in 2006,and put forward the ecological strategy of "Country park +" in 2018.In March 2021,the official draft of Hubei Province Country Park Design Standard was released.At present,the city has built 51 country parks.After reading a large number of literatures about country parks and green Spaces with similar functions,this paper constructed a comprehensive evaluation index system for the functions of Wuhan country parks based on 13 indicators,including the degree of complete facilities,the degree of beauty and the diversity index,which were selected for the three main functions of country parks,namely recreation,landscape aesthetics and ecological environment.Multi-source data were obtained through questionnaire survey,field research,sample sampling,big data climbing,network evaluation text and other methods.8 samples of country parks were selected for relevant research data.Through GIS spatial analysis and other data visualization methods,the quantitative data and visual analysis of the actual situation of recreation facilities and landscape environment of each sample country park were obtained.The results of quantitative analysis showed that jinyinhu National Urban Wetland Park had the highest comprehensive evaluation score,while Jiufeng National Forest Park had the lowest.Jinyinhu National Urban Wetland Park had the highest recreational function score,while Jiufeng National Forest Park had the lowest.The score of landscape aesthetic function was the highest in Jinyin Lake National Urban Wetland Park,and the lowest in Dugong Lake National Wetland Park.Longling Mountain Ecological Park had the highest ecological environmental function score,while Jiufeng National Forest Park had the lowest.According to the score of each index layer,combined with the actual situation,the reasons affecting the three categories of functions of the country park are analyzed.The analysis results show that the traffic conditions and the degree of complete facilities have a great impact on the leisure function.Green visual ratio has great influence on landscape aesthetic function.The ecological environment is mainly influenced by land cover type.In addition to the quantitative study of the country park conditions from the objective perspective,the paper also conducts high-frequency word analysis,feature word classification and emotion analysis of the network text from the subjective perspective,so as to get the attention of tourists and the overall satisfaction of tourists.According to the analysis of the classification of feature words,the highest word frequency is generally the perception of park image,including park characteristics and types,etc.A few park evaluation results show that the word frequency of recreation activities is higher,which reflects the prominent leisure and recreation function of the park.After analyzing the emotion of the network text,it is concluded that fuhe Country Park and Jinyinhu National Urban Wetland Park have the highest degree of visitor satisfaction,while Jiufeng National Forest Park and Qinglongshan National Forest Park have the lowest degree of visitor satisfaction.In addition,the satisfaction degree of tulip theme park is relatively polarized,and the analysis result may be related to the charge of ticket.Finally,through correlation analysis of satisfaction and index data,factors affecting recreation experience of country parks were obtained,and suggestions were put forward to facilitate subsequent suggestions and optimization strategies for the construction and development of country parks in terms of facilities management and resource mining.
