The dynamic changes of plant community structures at different restoration stages in the aerial-seeding region in Otindag Sandy Land were studied,aiming to understand the restoration characteristics and change rules of vegetation restoration. From 2013 to 2017,vegetation survey tests were conducted in 11 aerial seeding areas in the Otindag Sandy Land. Correspondence analysis,correlation analysis,and Mann-Kendall trend analysis were used to analyze stages of vegetation restoration in the aerial seeding area and to discuss the status and role of each functional plant in the community based on a functional perspective. The results showed that it was divided into three recovery stages across 19 years. Moreover,after aerial seeding,the degree of dependence among the following seven functional plants of rubs/subshrubs,perennial weeds,annual/biennial weeds，perennial leguminous forage,perennial gramineous forage and annual/biennial gramineous forage,was decreased gradually.Community stability was increased by the number of recovery years. Dominant function type of vegetation restoration was not consistent in different restoration stages,resulting in timing management could be employed at different stages. Consequently,the succession stage and overall development trend of plant community are more conducive to the recovery and reconstruction of the vegetations in degraded sandy land.
