To investigate the spatial and temporal changes and causes of ecosystem services （ESs） in Taiyuan City, six ESs indicators were selected based on five periods of land use data from 2000 to 2020, while ESs were assessed using multi-source data with the help of the InVEST model and the revised universal soil loss equation （RUSLE）.
