%X This dataset aims to explore the impact of climate change and human activities on soil multifunctionality in arid regions of China. By searching relevant literature from Web of Science and China National Knowledge Infrastructure from 1900 to May 2023, 841 field studies covering 18189 sets of observational data were selected. The data includes indicators related to soil function, climate data (such as annual average temperature, precipitation, nitrogen deposition, etc.), ecosystem type, soil depth, and treatment intensity. Construct a predictive model using the H2O AutoML package to analyze the impact of future (late 21st century) climate change (temperature, precipitation, nitrogen deposition) and human activities (such as cultivation, grazing, and returning farmland to forests) on soil multifunctionality. The data quality was confirmed through 10 fold cross validation and multiple evaluation indicators (such as R ² and RMSE), and the results showed that the constructed model can effectively predict future changes in soil multifunctionality, with high reliability and accuracy.
