Abstract: In this paper, the dynamic changes of species composition, diversity, and coverage of aerial sowing plant communities in the Hunshandake Sandy Land were investigated continuously for 4 years by means of space-time instead of time, in order to reveal the law of vegetation restoration under aerial measures, and to provide the basis for maintaining the stability of vegetation in the aerial area. The results showed that:(1) The control area and the initial area of the aerial sowing were dominated by one or two year old herbaceous plants. With the increase of aerial time, the perennial species increased and gradually replaced the primary and secondary herbs. (2) The Pielou index was the highest after 4 a succession, the Partrick index was the highest after 9 a succession, and the Shannon-Wiener index was the highest after 10 a succession. During the succession process, the three indexes changed with different discipline. (3)The population of Hedysarum laeve reached its peak after 8 a succession (68.33%), and the community kept stable for long term; The population of Artemisia sphaerocephala population reached its peak after 3 a succession (10.17%), and the population quitted after 11 a succession; The population of Astragalus adsurgens Shadawang' reached its peak after 4 a succession (12.67%), and the population withdrew after 9 a succession; The coverage of Ulmus pumila var. sabulosa population increased slowly with the linear trend. Therefore the vegetation can be quickly restored in the Hunshandake Sandy Land under aerial measures, and it is conducive to natural vegetation succession. It is necessary to consider the restoring force of sand land before aerial seeding in the Hunshandake Sandy Land.
