In this era of actively advocating the construction of social and cultural civilization, cultural architecture and space have been attached importance to and played a more important role. The library 4.0 era brings about that the library, as an important carrier of cultural space, has acquired new functions and meanings. The functions, forms and services of the library are greatly different from those of the traditional public library. The community library has become the "living room" of public life and the "third space" of the city. People's functional needs for libraries are no longer limited to reading, and their behaviors in libraries are becoming more and more diversified. In order to meet the needs of public behavior, the library reading space forms a composite trend, the boundary of the space becomes blurred, and the space functions are compatible. This paper introduces the theory of environmental behavior to explore the relationship between people from the perspective of library public behavior and psychological characteristics. Thus, a space environment suitable for the diverse psychological needs of readers can be created, and the reading space will be more suitable for the needs of contemporary readers.The researchers analyzed and summarized the literature and cases related to the library space, analyzed the development trend and existing problems of the community library, and introduced the theory of environmental behavior and elastic space design into the space design of the community library. Through understanding the reading and communication behaviors of the users in the community library, this paper explores the internal relations of each space in the library. Through the investigation of users' behavior and psychological needs, this paper interprets the resilient space design of the library, which aims to break the inherent form of the library, explore the potential function of the space deeply, and enhance the resilience of the space.This paper is divided into six chapters. The first chapter, the introduction part of the thesis, the reasons for the choice of the argument, the purpose of the research, the background of the research, the status quo of the research are summarized, and the research object, content and scope of the paper are explained. The second chapter is the theoretical investigation of community library, environmental behavior science and resilience design. This paper explains the history and development of the community library, and analyzes the relationship between users, space and furniture based on environmental behavior. These arguments guide the research direction of the thesis and the design strategies and principles of the library. In the part of library behavior research, it summarizes the characteristics of the activities, behavioral needs and psychological needs of the library behavior subjects, and takes the behavior and psychological characteristics of the public as the starting point of the following research. In the part of library behavior research, this paper summarizes the characteristics of library behavior subject's activities, behavioral needs and psychological needs, and takes the behavior and psychological characteristics of the public as the starting point of putting forward the design strategy. In addition, the problems about resilience design are discussed, and the changes and development of the concept of resilience are described. This paper explains the characteristics, causes and influences of the resilient space of community library. Finally, the correlation between community library and resilience space design is analyzed. The third chapter, through the case analysis of the resilience design of community library space characteristics, from the space planning. Spatial interface. Move line and furniture to wait for 4 respects to undertake narrative. The fourth chapter analyzes the user satisfaction, demand, preference and other data of community library by means of questionnaire survey. Fifthly, through case analysis and questionnaire survey, this paper summarizes the composition, space design and model of the resilient space in the community library, and expounds the influence of the resilient space design on the community library. Chapter six, the last chapter summarizes the research results of this paper, and points out the shortcomings of this study. The author puts forward some opinions on the development trend of community library in the future.
