Evaluation of Urban Park Service Quality Based on Factor Analysis

Urban park is an important component of urban public green space which provides leisure, recreation, activity place, etc. Urban park service quality was evaluated by quantitative method in this paper to provide scientific evidence for renewal and development of urban park. 5 urban parks in Xinxiang, Henan province, China were selected as evaluation samples, and 13 indexes were evaluated, including plant landscape, cultural experience, activity place, ecological environment, road design, topographical management, fitness facilities, water landscape, service facility, night landscape, landscape aesthetics, information mark and shelter landscape. Then the data were analyzed by factor analysis. Results: the information contained in the 13 evaluation indexes had considerable repeatability. Therefore, 5 main factors including landscape elements, sports and entertainment, cultural quality, ecology and night scene and traffic facilities were extracted which accounted for 80.881% of total variation. The number of factor variables was far less than the number of index variables, which reduced the complexity of evaluation and indicated that factor analysis had good dimension-reducing effect. Based on the results of factor analysis, not only the contribution rate of each index and each factor in the park service quality evaluation, but also single factor scores and comprehensive scores in different parks could be obtained, which facilitated the analysis and comparison of service quality of different parks. Our work can provide support for urban park renewal, reconstruction and development, thereby promoting the urban park service quality.
