The mass media is the main front of the science popularization. In recent years, China's science popularization has shown a good trend of development. But at the same time, some problems still exist, such as the lack of professionalism in the science popularization, the difficulty in balancing the scientific correctness and the readability, and the insufficiency of dissemination of scientific methods and scientific spirit. The main reasons are as follows:the insufficient support to the science popularization of mass media from the whole society; the difficulty in transforming the discourse system of mass media and the scientific discourse system; the weak scientific foundation and social responsibility of some mass media practitioners. In order to improve the science popularization ability of mass media, it is suggested to increase the support for media science popularization through multiple channels, strengthen the cultivation and the training of media science personnel, and improve the quality of media science popularization through the whole process.
