The science communication community believes that the front-line researchers should be encouraged to take active part in science communication activities. However, how front-line researchers understand scientific communication will directly affect their actual participation and concrete action. Investigation in front-line researchers shows that they have different dimensional demands of science communication. Concerning those demands, popularization of science, promotion of science and technology, and news publicity are three relatively mainstream ideas, which have very clear pragmatic motive. The paper analyzes the multi-dimensional influence of this pragmatism appeal on science communication action, and proposes that on the basis of respecting the multi-dimensional appeals of front-line researchers, they should be encouraged to carry out multi-level science communication practice in combination with the concrete reality, so that it would be of great benefit to the healthy development of science communication in China.
