During the development of rural settlements, the loss of distinctive rural characteristics, caused by the contradiction between urban expansion and the ideal of pastoralism, has attracted widespread attention from researchers worldwide. To effectively understand the development and trends of the Research of Features and Characteristics of Rural Settlements (abbreviated as RFCRS), this paper uses the knowledge mapping software CiteSpace to conduct co-citation analysis, research collaboration analysis, keyword clustering, and keyword co-occurrence. The study analyzes the basic concepts, the literature distribution characteristics, research clusters, key issues, and development trends of RFCRS. The research found that the current key issues in RFCRS include “Eco-logical services and environmental protection of rural settlements”, “Sustainable planning and architectural design issues of rural settlements”, and “Human settlement environment and service facility construction of rural settlements”. This paper predicts that future RFCRS research trends will focus on the study of landscape features and characteristics based on ecology, climate, and aesthetics; study of architectural features and characteristics based on characteristic factors and hierarchical structure; and research on rural revitalization based on sustainable development principles. The paper also offers four priority research suggestions for researchers from different disciplines.
