Abstract: In 2020,at the Jiangle state-owned Forestry Farm in Fujian Province,high-quality Cunninghamia lanceolata and Liriodendron chinense were selected as the species for clearing and renovating pine forests,creating a mixed forest of L. chinense and C. lanceolata and high-quality C. lanceolata stands. The growth,stand quality,and soil physicochemical properties of the stands were investigated and analyzed in 2023. The results showed that in the mixed forest of L. chinense and C. lanceolata,with a mixing ratio of 2 L. chinense and 1 C. lanceolata,an initial planting density of 2500 plants·hm^-2,and a row mixed pattern,the structure of the 5-year-old mixed forest in the early stage of canopy closure was relatively stable. L. chinense showed strong growth adaptability and effectively promoted the growth of C. lanceolata. The tree height,breast height diameter,and individual volume of C. lanceolata in the mixed forest increased by 6.51%,11.78% and 28.99% respectively compared to pure C. lanceolata forest,and the volume was significantly higher than that of pure C. lanceolata forest,which was 1.53 times that of pure C. lanceolata forest. The soil quality of mixed forests had been improved. Compared with pure C. lanceolata forests,the chemical properties of soil pH,soil organic matter,total nitrogen,hydrolyzed nitrogen,available phosphorus,and available potassium in mixed forests had increased by 11.40%,11.12%,38.50%,21.84%,65.03% and 21.41%,respectively. The physical properties of soil moisture in mixed forests had been significantly improved compared to pure C. lanceolata forests,especially in terms of soil water retention and aeration performance. The research results could provide reference and inspiration for the transformation of pine forests in northwest Fujian.
