Based on modern ecological theory, this paper starts with the analysis of the information transfer content, process and characteristics of the library's public opinion information service, and explores the library public opinion information service ecosystem model. The library public opinion information service ecosystem takes the specific public opinion information service as the main content, and takes the activities of the information service as the development basis to realize the communication, interaction and sharing of the public opinion information among different subjects. The system consists of three elements, the main body of public opinion information is the core element, the ontology of public opinion information is the intermediate platform, and the public opinion information environment is the influencing factor. The system has analysis, service, and feedback functions. The forward information transfer and feedback information transfer realizes the bidirectional flow of information interaction between different public opinion information subjects.
