Abstract: 2-year permanent plots of mixed stands of Cunninghamia lanceolata and broadleaved tree, formed by planting Altingia gracilipes and Schima superba of middle subtropical common sight evergreen broadleaved native soil species, were observed. Under the canopy of sprout land of Cunninghamia lanceolata, the function of water conservation was strengthened, the soil fertility was raised, the condition of forest microclimate was improved ,and the combustibility was dropped after transformed mixed stand of Altingia gracilipes and Cunninghamia lanceolata, and mixed stand of Schima superba and Cunninghamia lanceolata Cultivated evergreen broadleaved native soil species under canopy of Cunninghamia lanceolata was an effective biological measure for improving quality of ecological setting of Cunninghamia lanceolata and for improving scientific management of second growth and low yield stand of Cunninghamia lanceolata.
