Abstract: In order to explore suitable vegetation restoration models in arid valley areas, the arid valley areas in the upper reaches of the Minjiang River basin was selected as the research object, two types of land preparation were set up, i.e. level-terrace soil preparation and scale-shaped pit soil preparation, and different coverage treatment and fertilization types were carried out in each land preparation type to study the impact of different vegetation restoration measures on the characteristics of vegetation diversity. The results showed that level-terrace soil preparation was generally more beneficial to the increase of plant species number than scale-shaped pit soil preparation. The community species diversity index of different restoration measures was different in different degrees. Compared with the control, different restoration measures generally reduced the diversity of shrub species and improved the diversity of herb species, which might be related to short restoration time and different life forms. Due to the short restoration time, the plant communities of different vegetation restoration measures were in an unstable state. In general, the level-terrace soil preparation was better than that of scale-shaped pit soil preparation, stone was better than plastic film and sun-shading net, formula fertilizer was better than organic fertilizer, and level-terrace soil preparation + stone + formula fertilization restoration measure were more conducive to the improvement of diversity and community stability, which was a better restoration measure in this area.
