英文摘要	Due to the strong heterogeneity of the karst ecological environment and the complexity of soil conditions, soil quality (SQ) evaluation has not been widely used in karst vegetation restoration areas, and there is no unified consensus on the SQ restoration status in the region. This study takes the karst vegetation restoration area in southwest China as the research object and constructs a soil quality index (SQI) by quantifying multiple soil properties to explore the impact of different vegetation restoration strategies on SQ. Nineteen soil quality indicators, including the soil physical and chemical properties and microbial characteristics, were measured as the total data set (TDS). Different indicators selection methods (total data and minimum data set) and scoring methods (linear and non-linear) were employed to evaluate the influences of various vegetation restoration strategies (NR, natural restoration forest; ZB, Zanthoxylum bungeanum forest; TG, pure Tectona grandis forest; CK, cultivated land as control) on soil quality in karst rocky desertification areas. The results showed that soil moisture content (SMC), soil organic carbon (SOC), total calcium (TCa), and bacteria quantity were determined as the minimum data set (MDS) for estimated SQI based on principal component analysis. Among the four SQIs, the nonlinear scoring method had higher values than the linear scoring method, and SQIW-NL performed better in estimated SQ (R-2 = 0.819). All SQIs showed that NR > ZB > TG > CK, with no significant difference between different vegetation restoration strategies. However, all SQIs were higher than CK. Regardless of whether it was natural restoration strategies or artificial afforestation strategies, both could enhance the SQ in karst rocky desertification areas. Natural restoration strategies were superior to afforestation, yet without significant differences. Tailored vegetation restoration strategies could be implemented in karst rocky desertification areas based on the needs of agricultural production and ecological functions when conducting vegetation restoration.
