The purpose of this paper is to deeply explore the community participation model and its effect in the design of rural human settlements. In today's society, the living environment in rural areas has been paid more and more attention, and how to achieve better design through the participation of community residents has become an important issue. Through comprehensive literature review, case analysis and field investigation, this study systematically discusses the impact of different community participation models on rural human settlement design under the guidance of AHCI standards. In the literature review part, this paper first reviews the relevant research on rural human settlement design and community participation, and emphasizes the role of community participation in improving design quality, promoting community development and protecting environment. In the part of research methods, the methods used in the research are introduced in detail, including data collection, case selection and analysis methods, so as to ensure the scientific and reliability of the research. Then, the paper discusses four models of community participation: low-level community participation, collaborative design, community autonomy and participatory planning. With the support of specific cases and data, the advantages and disadvantages of each model are analyzed, as well as its application in rural human settlement environment design. Then, this paper discusses the effect of community participation model on the design of human settlements. It analyzes how community engagement affects various aspects of design from the perspectives of community identity, sustainability, social cohesion, innovation and diversity, and the balance of power. Through case analysis, the paper demonstrates the positive impact of community participation on design, such as enhancing residents' sense of identity with the design scheme and promoting the formation of social cohesion. Comprehensive case analysis and literature review, the paper discusses and analyzes the model and effect of community participation. The results show that the choice of different community participation models should be flexibly determined according to the specific circumstances and needs of rural areas. At the same time, community participation can promote the sustainability of community development while improving the quality of design. In short, this paper provides an in-depth study and comprehensive analysis of the community participation model and effect in rural human settlement environment design, and provides theoretical and practical support for achieving better human settlement environment design. Future research can continue to deepen the comparative study of different community engagement models to better guide practical design practice
