Abstract: Public satisfaction is the main base to measure the service quality of urban parks. In this study, six factors influencing the service quality of urban parks, namely, place environment, landscape environment, culture environment, eco-environment, traffic environment and facilities environment, were screened and been subdivided into 18 impact indexes. Three-hierarchy Analytic Hierarchy Process (AHP) model consisting of target layer, factor layer and index layer was established and the service quality was selected to be the target layer. Three urban parks of Zhengzhou, Henan Province, namely, People’s Park, CBD Park and Zijinshan Park, were the objects to be evaluated and 150 visitors of each park were surveyed about their satisfaction degree with quality service. Super Decisions (SD) software which can perform the AHP calculation, was used to obtain the weight of elements of each layer relative to the elements of the previous layer as well as the sequencing of total weight. Survey data of public satisfaction were combined with element weight to obtain the factor score and comprehensive score of service quality of the three parks. The result indicates that the service quality of CBD Park is the highest and can provide service of high quality to the public. Thus, CBD Park can be used as the model for the renovation and new parks’ construction.
