Abstract: Cunninghamia lanceolata is an important industrial tree species in Shizong County. However, the continuous planting of pure forest for several generations has shown the decline of woodland fertility, the decline of tree quality, and the inability to achieve continuous high yield and increase income, which seriously affects the depth development of the wood industry. Based on the analysis and description of the main contents of the implementation of Chinese fir mixed forest and the relevant important technical measures for the success of the mixed forest, combined with the development goals and current situation of the forest industry in the county, this paper summarized the suitable forest mode for the implementation of Chinese fir mixed forest and put forward measures and suggestion for the implementation of Chinese fir mixed forest in view of the existing problems in the development in order to provide reference for the future development of Chinese fir mixed forest.
