Abstract: Sequoia sempervirens has been introduced for over 20 years in several provinces of Eastern and Southwestern China. In this study, investigations were made of the growth features of clonal seedlings of Sequoia sempervirens introduced in Miyi county, Sichuan province. The results displayed that the plants had a healthy growth, without diseases, insect pests, deadwoods or spike tops. There were more sprouts at the altitudes of 1 480 m~1 500 m. The data analysis result showed that the 9 years old Sequoia sempervirens had 3.35 m tree height and the average DBH of 5.52 cm at the altitude of 1 480 m~1 540 m. The best individual had the tree height of 8.4 m and DBH of 16.69 cm. Compared the growth condition in Miyi with that in Kunming, Guizhou and places of origin at United States, the results showed that the Sequoia sempervirens had a strong adaptability, and could grow in different introduced sites, but growing better in Kunming and Guiyang. According to the analysis of Sequoia sempervirens growth condition at each introduction point with different ecological environment (temperature, water and soil environment), the results showed that the Sequoia sempervirens could not adapt to drought environment, liked the soil in warm climate area with moderate rainfall and larger humidity, and it had a stronger insect resistance and could be introduced in south substropical areas such as the Anling River valleys and Miyi areas in Sichuan, and could be used as a garden greening and precious industrial timber species.
