The work aims to summarize the modification technology for fast-growing Chinese fir to provide references for the development and application of modified Chinese fir. By combing the relevant research literatures on the modification of fast-growing Chinese fir, the existing researches had been classified into reactive modification and non-reactive modification. The research status of Chinese fir modification was analyzed and evaluated by integrating the modification methods, modification mechanism and the changes of wood properties. The research methods and research status of the modified fast-growing Chinese fir were summarized and the future development of Chinese-fir modification was pointed out, for the purpose of providing help for further study on the Chinese-fir modification, so as to expand the application range of fast-growing Chinese-fir. In recent years, China has made some achievements in terms of Chinese-fir modification technology, but still lacks the comprehensive modification technology, which requires further study by the science researchers.
