Research on Evaluation System and Optimization Strategy of Community Garden Based on IPA Method: A Case Study in Wuhan, China

The intrinsic attributes and service functions of community gardens (CGs) are closely related to the stage of national development and social needs. With the gradual implementation of China's urban micro-renewal policy, many CGs have been gradually developed, but they still face problems such as poor operation and low participation, which urgently require us to carry out site-based research under China's actual national conditions. Constructing a human's perception value-oriented evaluation system and summarizing the optimization strategies according to the evaluation results can provide more systematic and targeted practical guidance for the construction of CGs in China. We developed a set of evaluation metrics for CGs based network text analysis, literature analysis, and expert opinions and collected 245 questionnaires from 20 existing CGs in Wuhan as a study sample. Using the Importance-Performance Analysis (IPA) method, we conducted statistical analysis of data for each type of CG. The results show that "Mosquito impact", "Facility maintenance", and "Social experience" are essential parts of residential-type community gardens (Resi-CGs) that are easily overlooked; that the users of commercial-type community gardens (Comm-CGs) consider that "Mosquito impact" is a serious deficiency; that campus-type community gardens (Camp-CGs) need to be optimized with regard to the aspects of "Crop stewardship" and "Leisure facilities"; and finally that there is no significant trend in the key improvement indicators of company-type community gardens (Comp-CGs) and the indicators like "Fitness and recreation experience", "Crop diversity", and "Aesthetics" need to be improved. According to the above results, we put forward specific optimization strategies to provide development guidelines and practical guidance for the future construction of CGs.
