Abstract: 【Purpose/significance】The application of experimental method in the field of library and information research in China is gradually increasing, but there is a lack of systematic review of the application of experimental method. This paper combs and analyzes the research papers on the application of experimental method in the field of picture and information in China, providing reference for the future related research【. Method/process】Based on the data source of 216 research papers using the experimental method, the application status, application characteristics and existing problems of the experimental method are deeply analyzed by using the method of bibliomet‐rics and content analysis【. Result/conclusion】This paper puts forward the optimization strategy for the application of experimental method in the field of graphics from five aspects: attaching importance to the rational interpretation of the method, broadening the application scope of the method, ensuring the reliability and validity of the research, promoting the depth of the research, and strengthening the reflec‐tion on the use of the method【. Innovation/limitation】This paper probes into the practical application of the experimental method in the field of library and information research in China and puts forward some improvement measures. Follow-up studies can further expand data sources, improve the integrity of research, and promote the development of experimental methods in this field.
