This is\u00a0becoming increasingly possible via the automated analysis of\u00a0remotely-sensed data. Here, we\u00a0quantify loess landforms using an\u00a0object-based image analysis (OBIA) method and use this classification to\u00a0describe the spatial variability of loess landforms. Quantitative\u00a0indicators are used to drive the spatial variability analysis of loess\u00a0landforms and explain their spatio-temporal evolution. Moreover, the\u00a0hypsometric integral (HI) and topographic interpolation are employed to\u00a0investigate\u00a0soil erosion\u00a0and development patterns of loess landscape. Results show that the OBIA\u00a0method classified loess landforms to an accuracy of 88.7 %. The derived\u00a0metrics in terms of the area, slope and complexity of landform shape\u00a0allow the determination of the spatial structure of the loess\u00a0landscapes. The HI value of the entire\u00a0basin is 0.486, representing the\u00a0mature stage of landform development, with relatively severe surface\u00a0erosion. Correlation analysis of HI values and related indicators in the\u00a0sub-basins shows that HI is poorly correlated with the area proportion\u00a0\u00a0of loess landform types and the total erosion volume in the basin but\u00a0shows a relatively strong correlation with the volume of erosion per\u00a0unit area.
