Public participation in community-organized disaster mitigation activities is important for improving disaster mitigation capacity. With data from 260 questionnaires, this study compared the current status of public participation in model disaster mitigation communities and nonmodel communities in a geological-disaster-prone area. Three community-organized disaster mitigation education activities were compared cross-sectionally. A binary logistic regression was used to analyze the effects of attitude, perceived behavioral control, disaster experience, and other key factors on the public’s choice to participate in community disaster mitigation activities. The analysis results indicated that model communities had higher public participation in two efforts, evacuation drills and self-help skills training, and lower participation in activities that invited them to express their feedback than nonmodel communities. The influence of attitudinal factors on the decision to participate in disaster mitigation activities had a high similarity across community types. The public participation in model disaster mitigation communities is influenced by factors such as subjective norms and participation cognition; the behavior of people in nonmodel communities is influenced by factors such as previous experience with disasters, perceived behavioral control, risk perception, and participation cognition and has a greater potential for disaster mitigation community construction. This study provides practical evidence and theoretical support for strengthening the sustainable development of disaster mitigation community building.

Abstract. Giving full play to the public's initiative for geohazard reduction is critical for sustainable disaster reduction under a government-led top-down disaster governance approach. According to the public's intention to participate in geohazard mitigation activities, this study introduces the analytical framework of the theory of planned behavior (TPB), with attitudes, subjective norms, and perceived behavioral control as the primary explanatory variables, with three added explanatory variables: risk perception, disaster experience, and participation perception. Survey data obtained from 260 respondents in Jinchuan County, Sichuan Province, China, are analyzed using structural equation modeling and combined with multivariate hierarchical regression to test the explanatory power of the model. The results indicate that attitude, subjective normative, perceived behavioral control, and participatory cognition are significant predictors of public intention to participate. Disaster experience is negatively associated with public intention to participate. In addition, the extended TPB model contributes 50.7 % to the explanation of the behavioral intention of public participation. Practical suggestions and theoretical guidance are provided for strengthening geohazard risk management and achieving sustainable disaster reduction. In particular, it is concluded that, while correctly guiding public awareness of disaster reduction activities, policymakers should continue developing participatory mechanisms, paying attention to two-way communication bridges between the public and the government, uniting social forces, and optimizing access to resources.

Since the proposal of the rural revitalization strategy, "livable", "suitable for work", and "beautiful" have become the development goals of rural areas in the new era, among which the improvement of rural living environment issues has become an inherent requirement for rural revitalization. This article is based on the provincial and municipal regions of the Yangtze River Delta region, constructs a performance evaluation system for rural human settlement environment governance, and uses the entropy weight method to explore the influencing factors of rural human settlement environment governance performance in the Yangtze River Delta region.
