This paper investigated the status of science popularization (S-P) by scientific and technical worker. The results show that they have a positive attitude and strong sense of responsibility towards S-P, but their frequencies of participation in S-P activities are not high, and there exist a phenomenon of contrasts between their thoughts and practice. The main influencing factors leading to this phenomenon include their time, energy, funds as well as lack of assessment. Meantime the responsibility of science popularization and the sense of self-worth are both the important driving forces. They pay more attention to broadcast science spirit and scientific rationality, and believe that they should enhance S-P ability, and establish a multi-party mechanism to promote S-P. This paper suggest: Perfecting the evaluation and reward system of scientific and technological projects, scientific and educational units as well as their workers; broadening the channels for carrying out S-P, as promoting the S-P work on new media, self-Media and informatization; Focusing on the content of S-P, vigorously propagating scientific spirit and enhancing public's rationality on scientific issues; Eestablishing professional voluntary S-P organizations in scientific research institutes and universities, focusing on positive guidance and incentives, and cooperating in many ways to form a joint force for S-P; Complete the emergency mechanism of S-P and improve the S-P capacity of scientific and technological workers.
