We investigated the development of soil aggregates on temporal and spatial scales. By analyzing the time of publication, countries and regions of publication, and keywords, we can grasp the research direction, hotspots, and trends of soil aggregates. In the last decade, the main research directions in soil aggregates have focused on the mechanisms of soil organic carbon on the stability of soil aggregates in the context of climate change and the role of soil aggregates in mitigating soil erosion, wind erosion, and heavy metal pollution. Hot topics in research on soil aggregates are the mechanisms by which different land management regimes or land use practices affect the stability of soil aggregates and the role of soil aggregates in the carbon cycle. Meanwhile, research on soil aggregates has been highly concentrated at low and middle latitudes and altitudes, with insufficient attention being paid to high latitudes and altitudes. Future research on soil aggregates must be conducted in the context of climate change. First, we studied the mechanism of interaction between soil aggregates and soil organic carbon to give full play to the carbon sequestration potential of soil aggregates. Second, its relationship with soil moisture was studied and its impact on the water cycle at different scales was explored. Third, we conducted further deep and extensive research at high latitudes and altitudes.
