In order to study soil nutrients and soil quality of different ecological restoration models in karst rocky desertification area of Guizhou Province, Zhenfeng-Beipanjiang River Demonstration Area of rocky desertification control in the Southwest Guizhou Autonomous Prefecture was chosen as the study area. Soil quality comprehensive index method was used to evaluate soil quality under four different ecological restoration models such as Zanthoxylum bungeanum, Lonicera japonica, Juglans regia and abandoned cropland. And the distribution of soil physical, chemical and microbial indicators under different ecological restoration models was analyzed. The results proved that the soil nutrient enrichment in 0-5 cm surface soil of the four ecological restoration model plots was obvious, and the overall nutrition index showed the downward trend with the increase of soil depth within 20 centimeters; compared with the abandoned land for a short period of time, the soil physical properties of fileds of Zanthoxylum bungeanum, Lonicera japonica and Juglans regia were better, the nutrient contents were higher, and the soil microbial biomass was significantly improved. The soil quality comprehensive index decreased in the order:Zanthoxylum bungeanum (0.671) > Lonicera japonica (0.664) > Juglans regia (0.597) > abandoned cropland (0.589), which indicates that Zanthoxylum bungeanum and Lonicera japonica have good effects on soil quality improvement, and play a positive role in improving soil environment in rocky desertification control.
