It was a typical instance of task promoting science development in 1950s. This paper， as the startup part of the practice on prevention and control of aeolian desertification and the development of desert science in China for 70 years， brief retrospect the consideration and practice of the strategic， perspectiveness and practicability on exploiting prevention and control of aeolian desertification from the central and provinces government’s departments to the scientific research units， universities and the team of scientists and individuals. Thanks to the efforts of work together， mutual support and joint research from the national policy and budget support， task-oriented and target acquisition to government management agency in different levels， department of railways and forestry， Chinese Academy of Sciences and universities， the practice on prevention and control of aeolian desertification and the development of desert science in China came to start the course of development.
