Based on Landsat TM data from 1992 to 2017, the second-class survey data of Jianshui County forest resources and the monitoring data of rocky desertification in Yunnan Province, with Mann-Kendall mutation analysis and trend analysis, the temporal and spatial variation characteristics of vegetation and the restoration of vegetation in different rocky desertification restoration models in Jianshui County of Yunnan Province in the past 25 years were discussed. The study found that during the 25 years, the vegetation cover of Jianshui County showed an overall upward trend with an average growth rate of 0.065%/10a. Since 2008, the growth rate increased from 0.077%/10a to 0.475%/10a. The area of vegetation cover in Jianshui County showed an increasing trend, no significant change, and the proportion of reduction trend was 55.32%, 34.44% and 10.24% respectively. For different restoration models, within the restoration time range of ten years, there was not much difference in the effect of vegetation restoration under the pure ecological forest mode and the mixed ecological forest mode. Within the restoration time range of 25 years, the mixed ecological forest mode vegetation restoration rate was obviously better than pure ecological forest restoration mode, and the advantages were mainly displayed in the later stage of restoration. In terms of species selection of pure ecological forest model, broad-leaved forests and alders had better restoration effects in the short term; in the long run, Yunnan pine and Che sang-tzu were better restoration species. In the mixed ecological forest model, the coniferous mixed forest restoration rate was the best both in the range of ten and twenty-five years, indicating mixed ecological forest model is a better mixed model. The study revealed the effects of different governance models on vegetation restoration, and provided a theoretical basis for optimizing

ecological restoration methods in rocky desertification areas.
