Abstract: In order to further understand the effects of different interplanting patterns on the growth and soil of Cuninghamia lanceolata plantation, pure Cuninghamia lanceolata pattern and Phoebe zhennan-Cuninghamialanceolata interplanting pattern were tested respectively. The results showed that the average tree height of Cuninghamia lanceolata in interplanting mode was slightly lower than that in pure forest mode（18.53 m）, which decreased by 0.09%, and there was no significant difference between the two. The average DBH of Cuninghamia lanceolata in interplanting mode was significantly higher than that in pure forest mode（24.98 cm）,which was 10.13% higher than that in pure forest mode. The highest soil water content（227.13 g/kg） was obtained at the sampling depth of 20～40 cm in pure forest mode. The maximum water holding capacity（553.71 g/kg） was the highest at the sampling depth of0～20 cm in interplanting mode. The maximum capillary water capacity（411.38 g/kg） was obtained at the sampling depth of 20～40cm in pure forest mode.
