In order to enrich the afforestation tree species in semi-arid area of west Liaoning, introduction trial of Pinus sylvestriformis was conducted. The results indicated that Pinus sylvestriformis was blooming and seeding since 14-yearold. Compared with Pinus sylvestris var. mongolica planted in local area, growth speed of Pinus sylvestriformis was slower in initial stage, but exceeded Pinus sylvestris var. mongolica gradually in 10 years. Height increment of Pinus sylvestriformis reached 95 cm per year, and showed higher adaptability and stability.
