Confined by its own and external factors such as limited scale, fragmentization and circle layer structure, the dissemination faces certain limitations. From the perspective of foraminifera knowledge popularization in China, this paper sorts out the development period and dissemination channels, reflects on the limitations, and puts forward targeted suggestions on the coordinated development between scientific popularization and public life, circle layer culture, and scientific innovation. It is expected that on the basis of following the dissemination law of minority scientific knowledge, the study would promote the positive development of its popularization by using the methods that fit its own characteristics and dissemination space.
