Abstract: Multi-ethnic villages are grass-roots residential units where multiple ethnic groups, multiple religions, and multiple cultures converge. Taking Wangjiajing Village in Haiyuan County, Zhongwei City, Ningxia Hui Autonomous Region as an example, this paper dissects the most qualitative research methods in the past, and studies the interaction space of ethnic groups from the perspective of humanization. By investigating the spatial behavior of ethnic groups, using environmental behavioral spatial cognition research methods, interviewing and recording local people, interpreting the spatial cognition map of the Hui and Han ethnic groups, and analyzing the path of ethnic public space and differences, it is concluded that the spatial characteristics of the Wangjiajing ethnic group 'lives together in the valley, living next to each other, tolerance of space, and coexistence of symbiosis', and the ethnic group's spatial identification of 'I in you and you in me' in a harmonious and symbiotic environment of multi-ethnic groups. This paper analyzes the spatial characteristics of this type of village in depth, explains the relationship between human and environmental space, hoping to provide new ideas for the current practice of rural transformation in multi-ethnic areas.
