The Yixing Yuantianjian small watershed is a provincial soil erosion key management area in the hilly region of southern Jiangsu. It has been implemented national control project for management, which typical and representative region. important to quantitatively evaluate quality under different land use modes then select suitable ecological restoration measures promote economic construction watersheds Used four types (forest land, garden arable abandoned land) as research object, 13 physical chemical property indicators were screened based on principal component analysis, correlation analysis Norm value calculation construct minimum data set (MDS) evaluation. results showed that variability was higher than study area. MDS affected by are sand content (Sand), total nitrogen (TN), available (AN), potassium (AK), porosity (TSP) bulk density (BD), provide valid information with high accuracy. index areas Jiangsu SQI forest (0.83) > cultivated (0.74) (0.66) (0.46), at medium level. AN factor limiting this watershed. This can scientific basis enhancement

Soil quality degradation induced by erosion significantly inhibits sustainable development worldwide. For assessment of soil variations in an area with a heavily fragmented micro-landscape gully erosion, 16 indicators were tested laboratory settings and selected principal component analysis (PCA). Meanwhile, prediction was conducted the random forest (RF) model its derived from 3-dimensional structure landscape (resolution, 0.01 m) obtained unmanned aerial vehicle (UAV). During RF modelling, 80 % Quality Indices (SQIs) estimated PCA randomly as training data, remaining used to validate result. The optimal SQIs shown include Mnd, bulk density, silt content, cation exchange capacity (CEC). Additionally, PCA-calculated SQI ranging 0.33 0.85 decreased decreasing elevation erosional area. Moreover, spatial predicted satisfied accuracy (R2 = 0.83 ∼ 0.86; RMSE 0.03 0.04) comparable SQI. Overall, variation attributed (13.4 24.1 %), slope gradient (8.0 13.4 relief amplitude (9.8 12.9 terrain roughness index (10.3 11.9 %). This study confirmed excellent performance for prediction, also indicated that ultra-high-resolution (0.01 (UAV) competent tool areas complicated microtopography limited availability sampling.
