The survey analyzes the adaptability of Langfang Yang introduced in Hexi Corridor and Longzhong Loess Plateau. The results showed that the seedling survival rate, seedling growth rate, afforestation survival rate and tree growth rate of Langfang poplar were higher than those of the native species Populus alba. In addition, it can be safely winterized everywhere. Its fast-growing nature, salinity-resistance and barrenness are obvious. It can be popularized in a large area in semi-humid areas of Gansu and in Sichuan-Sichuan irrigation areas.
